Causal lottery system

Occasionally replying to a few messages, today I started to reply to messages like before, even more than before, it's like a storm, okay!This crazy swiping of the screen has attracted all the fans who followed him to be stunned. They were so moved that they burst into tears and began to brush the topic #知道先生回回#. After this, Ding Lang's Weibo fans have increased a lot, and his influence has gradually increased. I broke through the original small circle and walked towards a broader sky【Hope.

Ding Lang originally had some character points, and with such a crazy brushing method, the character points soon reached 1000, reaching 1100, and finally he was able to draw a lottery.

It is distressing to say that a prize draw with [-] points of character value is very distressing, but Ding Lang has already figured it out before. The causal lottery system is originally that the ones that fall from the sky are all earned by him, and he has drawn a lot of them before. Skills, calligraphy and so on, I didn't dare to think about it before.He silently said "enter the lottery space", and the next second his consciousness entered the lottery space.

"The host's remaining character value: 1100 points, the lottery can be drawn: 1 time, do you want to start the lottery now?"

"Yes."

The options dial appeared again, and the lucky draw officially began.

Finally, the pointer stayed on the "survival skills".

The only survival skill that Ding Lang really drew before was medical skills, and military boxing was something that was only given when the system was upgraded.It seems that there are relatively few survival skills in the lottery.

He pressed the button of the slot machine with some expectation.

Then his face turned dark again - what is Shaolin broomstick skill...

The broom skill sounds great when you hear it...

Let me go to what the hell is that!

"Shaolin Broom Kung Fu is one of the authentic traditional equipment of Shaolin Temple. It is a movement created by Shaolin monks in daily life. It is very practical to practice every move. The enemy will take the lead."

Explain systematically and professionally.

So after learning the rhythm of becoming a sweeping monk...

Ding Lang swallowed the pill with some grief and indignation. From now on, he can eat the pill with a broom ←← after smoking Bajie, he didn’t want to take a broom to test his new skills immediately, it was indeed out of the system space There is no place to practice... But there is no broom in the system space.

Out of the space, Ding Lang stretched his waist, it was rare that he wanted to go to Zheng to reward himself with a delicious meal.

As soon as he said it, he turned off the web page he had been browsing for a day, and walked to the rented grocery room.

Because the business is getting bigger and bigger, the kitchen behind the store has also been expanded, and now the grocery room is not used very much, only some over-bought materials will be stored there, but at the beginning he signed it for a year The lease agreement, so those bakeware drawers and things are still there, and he can use them when he needs them.

On the way, Ding Lang went to the supermarket to buy some ingredients.

Speaking of which, when he got the skill of cooking at the beginning, he still felt cheated in his heart, but now he really realized the benefits of cooking, especially after breaking through the S-level cooking skill.

After working hard for a while, no matter what, you have to make time to cook a delicious meal to reward yourself, right?

This time he ate alone, so he didn't have to worry about other people's tastes at all, he just had to cook what he liked.Buy less ingredients, and a smaller portion of a dish will do.

Wang tofu is a must. Now his favorite dish is this dish, but he usually has no time to make it by himself when he is busy. The shops outside either do not know how to make it or the ones are not authentic.Almost every time he eats Wang Tofu, he feels emotional. Thanks to his system, he has won the culinary skills, otherwise he would never want to eat the Wang Tofu made by his grandfather for the rest of his life...

Chicken soup or pork rib soup is necessary for making Wang tofu. Today he bought a chicken and stewed the chicken as soon as he arrived at the grocery store. He read a book on mechanics by himself.

The more you understand this aspect of knowledge, the more you will feel small, and the more interested you are in this knowledge.Ding Lang knew that his physics foundation was indeed good, but it was still far behind Tangert's level. Now is the time to enrich himself, otherwise he can't always expect to win future technology by lottery.The first time he won the aero-engine in Future Technology, he didn't know that the ball represented the inventor's life, so he swallowed it in a daze, and he never used the Future Technology that was drawn later.

The chicken soup has been boiled for two full hours, and he only takes the clear soup, half of which is used to make Wang Tofu, and the other half is used to make boiled dried shredded rice.

After the two soy products, Ding Lang simply made a beef tenderloin with chilli.Pick off the fascia of the beef, cut the beef into thicker slices, marinate with starch, soy sauce, baking soda, and oil for 10 minutes, and then pat it loose with a knife.

As long as the oil is [-]% hot, you can pour the beef tenderloin into the pan and stir-fry slightly. After the color changes, put it out and set it aside.Leave some oil in the pot, then pour minced garlic and sauté until fragrant, then add Hang pepper and fry, and finally add beef tenderloin and shredded red pepper and fry together, add some cooking wine and oyster sauce, put salt before serving, and you are ready to eat .

Then Ding Lang ate two big bowls of rice with these dishes.

After eating this meal, he took a short rest and went for a walk. He was really full, and he lived to 99 after walking around after the meal!

Ding Lang rested for about a week. During this period, besides reading books for self-study, he also went to attend classes in the Department of Materials Science and Department of Physics. Anyway, they don't have many classes of their own now.

When I saw him coming for the first time, Professor Wu Mian, who was doing the roll call on the podium, was obviously very pleasantly surprised, and Wannian Yan Luo Wang also had a smile on his face——all the students sitting in their seats stopped talking instantly in shock , Sleeping people were also pushed awake——Professor Wu actually laughed! What the hell happened to Nima!

Ding Lang sat low-key in the back row, lowered his head and took notes, hiding his achievements and fame.

Professor Wu Mian is indeed a well-known master at home and abroad. Although he is a bit rigid, his lectures are very good and fascinating. Ding Lang listened with great interest and took many useful notes.You must know that he has a good understanding of metal matrix composites and ceramic matrix composites. Thanks to that dream, although there are many things that can be integrated in materials science, he really doesn't understand other aspects.The two lectures that Ding Lang went to listen to are about energetic materials, which refer to materials that contain energy.

He also went to listen to two lectures in the Department of Physics, and the professor spoke well. After all, he is a teacher of Capital University, and his level is not low.

In general, Ding Lang had a very fulfilling week this week.

When the research resumed, Ding Lang felt that he had a lot of new inspirations because of the week's rest.

Sure enough, the decision to take a break was the right one... He sighed and threw himself into the research again.

Although the research on metal matrix composite materials is still insufficient in Ding Lang's view, both the three assistants and Professor Wu Mian said that this achievement is already very good, and it is completely possible to apply for a patent with this project.

Materials issues are just an appetizer for aero engines.

In 88, the U.S. Air Force first initiated the development and implementation of a high-performance turbine engine technology plan, including NASA, the Air Force, Navy, Army, Defense Research Agency and seven major engine manufacturers participated in this plan, while Europe, Mainly the United Kingdom, including Italy and Germany, participated in the second phase of the advanced core military engine program. Britain and France, a pair of friends who love and kill each other, jointly implemented the advanced military engine technology plan. Russia also has a similar plan. .The goals of these programs are to increase the thrust-to-weight ratio, reduce fuel consumption, improve reliability, and reduce production and maintenance costs.

This sentence is easy to say, but it is difficult to do.Among them, Country M's High Performance Turbine Engine Technology Program (IHPTET) has achieved great success in terms of technology and commercial advantages, and Country M has begun to implement its follow-up program, VAATE.

On the other hand, Huaxia...the gap is indeed quite a lot.

Even though the aviation and defense technology has been vigorously developed in recent years, China's industrial base is much worse than that of country M. In fact, it is already very good to be able to develop to the point where it is today, but... it is not enough.

The author has something to say: In the past two days, it’s best to smoke Nima to replace the current and flexible Xueba who can’t get the 66 engine

The most advanced fighter jet in China - at least it has been successfully developed and has been witnessed, so I have to mention the J-series. On January 11, 1, the first test flight of the J-11 aircraft was quite high-profile, contrary to the attitude of the military in the past. , Many netizens took photos of the test flight, and this high-profile attitude also triggered a military boom at that time.

You know, when the F22 first entered service, the J-10, China's third-generation fighter jet, was released not long ago.

At that time, those pennies on the Internet could be said to be celebrating each other, and they all bad-mouthed Huaxia fighter jets, claiming that Huaxia would not be able to master the F20's integral coating hatch technology within 22 years. I also feel that China is too far behind country M.Unexpectedly, the J-11 was successfully tested in 20, and it was slapped in the face.

The J-20 is code-named "Veyron" and NATO is code-named "FireFang". According to the old standards, it is classified as the fourth-generation fighter, but according to the new standards and the standards of the E country, it is the fifth-generation fighter. It is a double-engine heavy stealth fighter. .As China's fourth-generation heavy-duty stealth fighter, the J-20 integrates the designs of many excellent fighters around the world, including the F-22's diamond-shaped nose, integral gold-coated hatch and bomb bay layout, the F-35's EODAS system and The improved DSI inlet (the J-20 uses the next-generation adjustable DSI inlet), the full-motion vertical tail of the T-50 has also been replaced by the full-motion differential vertical tail of this process, and the rear fuselage of the MiG 1.44 Design, including narrow-spacing dual engine nozzles, wide-spacing outward-sloping double vertical tails and ventral fins (these are all supersonic drag reduction measures).

In general, the basic layout of the J-20 is inherited from that of the J-10, and it also incorporates the excellent designs of a variety of advanced fighter jets in the world. Putting it into use, it will gradually form combat effectiveness in 2017.

However, in terms of engines, the J-20 is still worrying.

The official did not clearly explain the engine problem of the J-20, but the engine used in the first test flight of the "Veyron" does not seem to be domestically produced, and it is estimated that it will be replaced with a domestically produced engine when it is officially assembled into the army.The gap between domestically produced engines and international advanced engines lies in reliability and service life. According to data from a few years ago, the maximum service life of engines in country M reached 3000 hours, 1200 hours in country E, and 800 hours in China.

The new generation of engines must ensure that the aircraft has a high attendance rate. In this regard, domestic engines are worrying.Moreover, in terms of bypass ratio, the domestically produced ones are much higher than those of the M and E counterparts, which is very unfavorable for supersonic cruise.

Some people may be wondering why Huaxia can independently develop rocket engines and successfully apply them, while fighter jet engines cannot be mass-produced just after the technical difficulties have been learned?Even better car engines have to be imported?

In fact, in terms of design difficulty, rocket engine design is less difficult, and rocket engines are disposable, so the service life requirements for parts are very low.Finally, the amount of rocket engines is very small, and it is entirely possible to adopt the method of manual workshops and let senior technicians make them by hand. However, aeroengines must be mass-produced. Whether it is the level of basic industry or the number of technicians, China is not as good as the advanced countries in Europe and the United States.This is also the reason why Mr. Qian Xuesen advocated giving priority to the development of rockets in the 60s.

Moreover, if the thrust of the aeroengine is not enough, it can be made bigger, but the aeroengine of the aircraft is much more compact, so this cannot be done.

Of course, Chinese auto engines are still available. The reason for imports is due to profit factors. Who else is engaged in independent research and development in the domestic auto industry?

According to reports from country M media, in addition to the existing aero engines, Huaxia is developing four new types of high bypass ratio turbofan engines, but only two of them have been disclosed to the public so far.It seems that both the upgraded version of WS-10 and WS-15 may become the aeroengine of J-20.

The technical difficulty of the aero-engine itself has reached the peak of the current human industry, but the development time required is too long, and our basic scientific research is more than ten years behind.Common aviation engines such as the L-15 trainer aircraft, Mi-17 engine, and MBT-2000 all need to be supplied by the UKR. The recent domestic turmoil in the UKR, and the international community has mocked China. The tone of these words Incomparable sincerity seems to be really worried about Huaxia: the turmoil in UKR may cause Huaxia aircraft to face the pain of being stuck in the neck by the engine again!But anyone who thinks about it for a moment can figure out the schadenfreude in this statement.

Even if it is an ordinary aero engine, China cannot mass-produce it, because the country has limited resources in this area, and we are still very weak in terms of high-tech industrial foundation.Moreover, China's engine research, to put it bluntly, is completely alone, behind closed doors, and the difficulty and cost of research and development are quite high.

What Ding Lang wants to do is not just break through key technologies, he also wants to improve the level of basic scientific research in the country.

In this case, even if Ding Lang had the memory of Tangerte, it would not be enough.

No matter how talented and out-of-this-world Tangerte is, he is only one person, and compared to the outside world, he is more focused on himself.It is very difficult for Ding Lang to realize his dream—no, it can be said to be a fantasy.

Perhaps now the ceramic matrix composite material he has researched and the metal matrix composite material he is about to complete can be gradually put into mass production. From here, step by step, down-to-earth, we can always see hope.

You know, who can believe that China, which was poor and white 60 years ago, can return to the world's big stage today, has a complete industrial system, can send people to the sky, and can dive into the deepest seabed...?But Huaxia did it.

This must be thanks to those who underestimate Huaxia's defense against China. If it weren't for them, the stubborn Huaxia people would not simply kick away those countries that ignore him or simply give him a blank look, and focus on independent research and development.

I have to say that Ding Lang is a top student, and a very spiritual one.

Perhaps it is because of the memory of Tangerte, a genius at the top of science and technology, that his vision is much wider, which allows him to draw inferences from one instance and master the other in self-study courses, and his learning efficiency is quite high.In the process of self-study, Ding Lang even felt that his thinking was diverging, and inspiration flowed like he didn't want money.

Some time ago, the class I listened to in the physics department was about electromagnetism. When talking about electromagnetism, Ding Lang thought of microwave ovens.Microwave ovens are convenient and quick, and many people have them. It’s good to go in and turn them around a few times when hot dishes and rice are hot, and they can also be used directly for barbecues. Its radiation is relatively large.

In fact, the basic process of microwave oven production is not difficult, and the cost is not high. If the problem of radiation can be well controlled, it will definitely cause a sales boom in developed countries.

Ding Lang was a little inspired in this regard, so now that he has his own laboratory to use, he directly wrote this project on the schedule.For this research, he went to the market and bought several popular or relatively high-end microwave ovens, intending to take them apart to have a look.

Not only the microwave oven, Ding Lang's inspiration also flashed on his own profession.

After all, he is still a student majoring in computer science. If there is no flowering inside the wall, he patronizes the redness outside the wall. It is not beautiful after all!

That day he went to Longteng to look for Huang Ziqing. It happened that Huang Ziqing was in a meeting and he didn't want to disturb others, so he sat in the office and watched others through the blinds.

Longteng's entrepreneurial spirit is still good, and there is no such thing as fishing at work - anyway, the online game department can maintain the operation of the game at work, and the forum department works to manage and manage forums, delete posts, and the task of the video group is probably to watch some netizens. The uploaded video... If you say that you are serious about going to work, there is really nothing to fish for.

Ding Lang felt bored after watching it for a while, so he simply used Huang Ziqing's computer to play minesweeper.

Just then, he heard someone arguing outside the office.

quarrel?At work?

Although all the cadres of Longteng's various groups have gone to the meeting room to open the door at this time, everyone can relax a little bit, but there is no need to be so... bold, right?

The two members of the video group were arguing vigorously, while he leaned against the door and listened to someone's corner.He noticed that not only him, but many people outside had noticed the movement over there.

Ding Lang listened for a while, and it turned out that two people were fighting non-stop for the position on the front page of the website.One said that the sideshow of the 3D blockbuster directed by a certain director was extremely exciting, and the other said that I fell asleep after watching that crap movie!In short, no one would give in.

The quarrel was quite boring. Ding Lang was not interested in listening to it anymore, but his heart was ready to move—3D movies were developing rapidly. In the class a few days ago, the teacher also mentioned the production of special effects for movies. Majored in electronic engineering, but it can also be related to post-production special effects, and he is quite interested in this.

However, it is not necessary to use post-production special effects as a research object.Probably because he pushed himself too hard some time ago, the effect was not as good as a good combination of work and rest. Now Ding Lang has completely devoted himself to research, and basically controls his daily working hours, except for class, eating, and research. In addition, there is always some personal time for listening to lectures.

Now that he has started to be interested in post-production special effects, besides his professional courses, Ding Lang has also started taking film post-production classes. He still has a little basic knowledge of this, and he still knows how to use FLASH _(:з」 ∠)_ Of course he can do Kong Lianshun-level special effects! [The firm face Ding Lang now has a free schedule, but he feels that there is not enough time. He also understands his urination. He is a little interested in everything and knows a little bit about everything. As a result, his interests are too broad and he doesn't learn well.

The author has something to say: It’s too late every day _(:з”∠)_ Nima, is it because I’m slow in typing? 67 Little calligrapher Su Yiyi

The author has something to say: I'm sorry I just fell asleep while writing... When the capital began to warm up, the class prepared a spring outing.Ding Lang was not interested in this, but after all, it was a class group activity, and he couldn't go alone, so on a Saturday, students from two classes of electronic engineering and Zhao Qian went to a certain park in the capital to play.

It is completely inappropriate to say that it is a spring outing - the park is crowded with people, and there is nothing interesting except for the barbecue in the afternoon. There was an accident while rowing. Ding Lang was looking at the ducks in the water curiously. The only two girls in the electronic engineering class on a boat screamed. It turned out that they didn't know how to row a boat at all, and they were just trying to have fun, but the boat drifted straight to the middle of the lake out of their control. In a panic, the two girls His boat also collided with someone else's. If the other party hadn't reacted quickly and stabilized his boat, it is estimated that the people on both boats would have fallen into the water.

After rowing, the group went to KTV again. After singing the song, they went to rub their hands for a meal. Zhao Qian's treat was the most exciting event of the day.All in all, this so-called class reunion is completely boring.

Miraculously, in that restaurant, Ding Lang met an old acquaintance - Wu Nan.

Obviously, the other party was also very surprised to see him, and after a few words with his friends, he ran over to greet Ding Lang: "Xiao Ding also eats here? What a coincidence, I also made an appointment with my friends to eat the pig's feet here." Soup."

Ding Lang still had a good impression of this chubby uncle who looked rather simple and honest. Hearing his question, he smiled and explained: "Hello, President Wu. It is indeed a coincidence that our class is here for dinner today."

Wu Nan was smiling at this time, looking very friendly. Other students who didn't know him, including Zhao Qian, couldn't imagine that the person in front of him was the chairman of a well-known domestic real estate company and the vice president of the Capital Calligraphy Association— —Perhaps the latter will be more surprising, because Wu Nan seems to have nothing to do with calligraphy.

Wu Nan raised his wrist to check the time, and said apologetically, "We're going to start eating soon, we don't have time this time, next time, I'll treat you to dinner next time, and I just have something to ask our future calligraphy master !"

Ding Lang cleared his throat in embarrassment, pretending not to hear the phrase [Future Calligraphy Master], and pretending to be relaxed, he said, "It's okay, President Wu, go quickly! If there is anything I can help, I will definitely help!"

After Wu Nan left, Liu Jianwei came over and asked who that person was.

"The vice president of the Capital Calligraphy Association, the main business seems to be the chairman of a company...Didn't I tell you last time that I went to the Calligraphy Association exhibition? He helped a lot." Not only that, but there is a paragraph During that time, Wu Nan sent text messages and calls to Ding Lang almost every day, and continued to harass* (harassment, just to persuade Ding Lang to join the Capital Book Association, even if it was just a name. Ding Lang is just For a college student, it is not appropriate to be called a calligrapher. It can only be said to be a rising star in the calligraphy world. For this new star, Wu Nan has spent a lot of effort, even though Ding Lang is just a person who has met him. It's just a calligraphy genius for a few times, but Wu Nan just feels that he hits it off.

Ding Lang's handwriting was very good. Apart from the huge set that had already been hung in the exhibition hall, there were also a few scattered pieces of handwriting that were sent to the competition that day. They were all Ding Lang's works. Everyone else, including Wu Nan, I prefer the "The Greatest Kindness Is Like Water" written by Ding Lang.In fact, those four words have a momentum completely different from their original meaning, and the font can be regarded as ostentatious to a certain extent, and the words attract people's attention to a certain extent.However, Mr. Qian Yongqing from the Calligraphy Association disagreed. He thought that the word Shangshanruoshui was not suitable for Ding Lang to write.However, because most people agree with "Shangshanruoshui", Mr. Qian Yongqing did not object any more, and Ding Lang has hired a professional mounter to mount Shangshanruoshui with precious wooden materials. Then just pick a place to hang it. good.

Ding Lang is still thinking about the time when he first met Wu Nan. At that time, he was still busy selling moon cakes to earn money to prepare for experiments. Now he has his own laboratory—even though it is said to be his laboratory, it is actually rented. ——But he is now about to get the multi-million experimental fund of the national law!

"So——Ding Lang, you really became a little calligrapher?" Wang Ruiqing's point was always wrong!

The person who was asked was rarely taken aback, and then explained: "I'm just a hobby..."

He Xu smiled: "You can do so well as a hobby, why don't you be mad at someone who learned calligraphy in elementary school?"

Hearing what he said, Ding Lang couldn't help but think of the tragedy that he was never allowed to enter the school and was punished by the teacher, so he couldn't help laughing.

What Wu Nan said to help is very simple.

On his grandpa’s birthday, the old man has always liked calligraphy. Wu Nan also loves calligraphy, so she thought of presenting a special gift on the grandpa’s 70th birthday: letters and blessings from many calligraphers.

Ding Lang didn't know that Wu Nan invited calligraphers who had been famous for a long time, but he was the only one who had gained a little popularity through the exhibition of the Capital Calligraphy Association.He thought that the vice president of the Calligraphy Association, after all, knows a lot of people, and it is even more impossible to worry about all the things or the birthday of the old man, so we are not allowed to relax?You only need to write one page, and Wu Nan will bind all the written papers into a book and give it to the old man.

He Shou's words are not difficult to write. Although Ding Lang has never met Wu Nan's father, he has heard him mention it.

The old man lived through hardships in the first half of his life. Not long after Wu Nan was born, his wife, Wu Nan's mother, died of starvation because of the famine. The old man was the father and the mother to bring Wu Nan up and earn money. For him to go to school, Wu Nan succeeded in the end.

Ding Lang respected such an old man very much.Wu Nan was already a friend in his heart, so there was no need to mention writing for his friend's father.

After much deliberation, he still wrote down the most simple and common sentence - happiness is like the long flowing water in the East China Sea, and life is not as old as Nanshan.

After writing and printing his own stamp, Ding Lang put the paper aside to dry.

Now it is just preparing gifts for the old man, and it will be the time when the old man really celebrates his birthday at the end of the month.Ding Lang was invited by Wu Nan, he respected the old man, and he would indeed attend.

Besides Wu Nan, there are also people asking Ding Lang for words recently.

Last time, the words "Shangshan Rushui" caused a lot of discussion in a small range, and it became popular on a small scale. Someone dug up the "Teacher's Talk" that he took out when he first entered school to participate in the school competition, and found that this was called Ding Lang's young man seems to be an all-rounder in calligraphy, he can write small and large characters, and he can also write upright or jumping characters.

The pair of Shangshan Ruoshui had an offer to buy some time ago, and the other party was quite generous. After all, the name Ding Lang is not well-known in the calligraphy collection circle, but because several masters of the calligraphy association have praised it, the value has increased. up.The man bid [-] yuan for this painting, which is quite a generous price.

Ding Lang couldn't help lamenting that he wanted to earn some money and worked so hard to get up early in the morning to make fresh meat mooncakes. Although he had only done this for a few days, it was already very hard work, let alone Chen Uncle and Chen My aunt is busy all day, from four o'clock in the morning to eleven o'clock in the evening.

As for writing, it's so easy...Someone almost gave it to you with RMB.

Of course, Ding Lang knew that he couldn't say that, but he still felt a little emotional.

Now that the national special funds have not arrived, the [-] can be used to add some experimental equipment first.

The experiment of metal matrix composite materials is basically like this. Although Ding Lang always feels that something is wrong, the final result is that the performance of the high-temperature, high-performance, high-niobium-aluminum-titanium alloy produced is slightly behind the one in memory. There is no other accident. You can apply for a patent first and then start researching other things. When you have time, you can find the problem slowly.

The reason why ceramic matrix and metal matrix composite materials are studied is to make the temperature of aero-engines higher. Although it sounds simple, it is actually very important. If the related materials are successfully developed, they can directly affect the service life and quality of aero-engines. Safety goes up, and this is obviously the place where domestic engines need to be improved most.For example, the environment of the combustion chamber, high temperature, high pressure, and high efficiency, such a design is very limited by the level of materials. There is still a big gap between domestic materials and imported materials, and in this regard, developed countries also restrict exports to China. It is said that Huaxia is really blind, and it is another thing that needs to be developed from scratch.

Not to mention domestically produced engines, even the engines made in country E are not as serviceable as western engines, and the overhaul time is short. No matter how reluctant you are, you have to admit that the design level and actual industrial level of country M are ahead of China. 20 years or so.

Aviation development technology involves metallurgy, materials, mechanical processing, mechanical manufacturing, thermodynamics, aerodynamics, fluid mechanics, control science, etc., and it is more appropriate to call it the "flower of industry". Three-quarters of all disciplines in upper engineering must dedicate their highest achievements to aero-engines.Leading the world in aero engine technology means that the country's scientific and technological achievements have surpassed other countries.

Materials and craftsmanship are the two fundamental problems China is currently facing.

First of all, we cannot manufacture the materials needed for the core components of aero-engines. The turbine blades of jet engines need high-strength and high-temperature-resistant materials. The turbine blades of modern jet engines usually withstand 300 to [-] degrees Celsius during work. At the same time, it has to withstand the custom of about [-] meters per second, and the huge air pressure brought about by it. In the world, high-temperature and high-performance high-niobium titanium-aluminum alloys are generally used. Now Ding Lang will give this thing to Su. up.

This is so cool _(:з)∠)_ It's so sour, I can't believe it!Simply can not stop!

68 another fund

The author has something to say: I closed my eyes and fell asleep and then woke up after two o'clock_(:з"∠)_I'm sorry these two days are so late,,, try to update before twelve o'clock tomorrow The country has been researching and developing niobium-titanium-aluminum alloys, and it has indeed achieved results in the past two years.A few years ago, there was news that the State Key Laboratory of the University of Science and Technology had successfully tested and high-niobium titanium-aluminum alloys would be put into the stage of industrialization, but several years have passed, and the industrialization has not yet been realized.

Although the version that Ding Lang gave to Su is still slightly different from the version of Tangerte in "Dream", it is not bad at all compared with the current international advanced level, and it is still a step further than the previous achievements of the University of Science and Technology. ——Professor Wu Mian told Ding Lang this.

The results of this experiment obviously shocked the entire Department of Materials Engineering of Capital University. Professor Wu Mian looked at the finished product and was careful when testing the data. I am Huaxia!"

The tearful Professor Wu obviously gave Ding Lang and his three assistants a big shock.

They, who had gradually calmed down from their excitement, also became emotional because of Professor Wu's tears. Everyone's emotions became excited again, and even Ding Lang couldn't help hugging them, laughing and crying.

Looking back, Nima is really embarrassing...

Although Ding Lang himself added some ideas of his own to this study, the experimental track still came from Don Dalter.Walker’s, it’s shameless to cry because of this ＿(:з)∠)＿

But... Seeing the older generation of researchers crying for the progress of the country, I was completely touched.

Different from the ceramic matrix composite material last time, the successful research and development of high-niobium titanium-aluminum alloy is much more conspicuous. Before Ding Lang's patent application materials were ready, personnel from relevant national departments came to the door.

——Of course not here to check the water meter and deliver the courier.

The status of materials science at Capital University in China is very good. Professor Wu Mian is the highest-ranking professor in the current department, and his teacher, Mr. Peng Li, is the father of materials science in China. Member of the Presidium of the Academician Conference of the Huaxia Academy of Engineering.

This time he brought someone here.
