God-level Xueba system

[The host has a lucky draw chance for mission rewards! 100 points can be actively redeemed for a lucky draw!Probability of lottery draw: 90% garbage; 9% projects in the basic auxiliary zone; 1% projects in the high-tech zone]

Yan Xin rolled his eyes.

The probability of getting garbage is too damn high, right?
"Pump it, smoke it!"

Anyway, I was praised today, so I don’t smoke for nothing!
A huge turntable appeared in front of Yan Xin's eyes, and the pointer swished up a second later, Yan Xin stared at the red high-tech zone with full expectation!

"High-tech! High-tech!"

Yan Xin's parents thought the child had been stimulated by something, so they yelled in the room.

But the college entrance examination is approaching, and this kid has been working hard recently, maybe it's because of too much pressure?
Of course Yan Xin was under a lot of pressure!
This big turntable has inertia!This is also the most likely cheating phenomenon when drawing a lottery!
The pointer gradually slowed down, Yan Xin stared at the system panel!

But to Yan Xin's disappointment, the pointer moved slowly over the high-tech zone, and then stopped at the trash!

[Congratulations to the host for getting the trash! 】

[Get a small bag of Ollie for biscuits, I hope you will not be discouraged!come on! 】

Grass you XXXX!

Yan Xin watched a small bag of blue chocolate sandwich biscuits suddenly appear in her hand, and couldn't help her mouth twitching.

As expected of garbage!
Give Lao Tzu a snack, it turns out to be a pirated brand of Ollie biscuits!

Oreo cookies want to hit someone!

Forget it, it's useless to set gas with a system, it's more important to do business!

Watching Ollie give the biscuit in front of her eyes, Yan Xin tore open it and took a bite.

I do!

Not to mention, it tastes good!

It seems that getting garbage is not necessarily a bad thing, at least you can taste the snacks pirated from the system!
"Open the system panel!"

Yan Xin hummed helplessly.

【Task: To be released】

[Reminder: After mathematics, Chinese, English, and comprehensive science reach the full level, the system will update in real time according to the next learning task of the host!]

Looking at the prompts on the system panel, Yan Xin felt that it was time for the next step of learning.

After all, there is no limit to learning. If you want to become a master, you must prepare one step ahead!
After the last simulated competition, Yan Xin understood that what she had to study hard now was of course the university knowledge.

According to Yan Xin's understanding, apart from advanced mathematics and English CET-[-] and CET-[-], the rest of the university's basic courses are professional courses.

Like those amateur courses: college students' mental health, college students' safety education, situation and policy, military introduction, etc., Yan Xin feels that it is completely unnecessary to study now.

However, professional knowledge is more important.

Such as machinery, environment, materials, chemistry, biology, food, advertising, finance, etc., are the most popular majors at present.

And these professions will branch out in different directions.

For example, materials majors are divided into materials science and engineering and materials engineering; chemistry majors are divided into physics and chemistry, organic chemistry, inorganic chemistry, etc.; biology majors are divided into gene direction, protein direction, cell direction, fermentation direction, etc.

There is no difficulty for Yan Xin when learning these professional courses.

After all, college students can pass the final exam as long as they pass the exam.

Therefore, the most popular sentence among college students is long live the pass, so that they don't have to pay for re-education.

From this point of view, the knowledge of various professional courses is not very attractive to Yan Xin.Rather, the research value of these professional directions is more worthy of Yan Xin's pursuit!
What attracted Yan Xin the most was naturally the research fields of these professions.

If you want to make a difference in the research field, you must publish valuable scientific research papers in international journals.

Looking at the current publication of Longxia's SCI journal literature, the data shows that Longxia's current SCI articles are indeed quite a lot, and the number will rank first in the world in 2020!

But the impact factor of Long Xia's published literature is very low!It even ranks among the bottom in the world!
This also exposed from the side that although Long Xia is very strong in publishing SCI journal papers, he still rarely produces new and practical things.

To put it bluntly, it means changing the soup without changing the medicine, treating the symptoms but not the root cause.

Research results have no real meaning!
Yan Xin thinks this is one of the reasons why Long Xia's technology has been stagnant!

Looking at the various majors on the computer screen, Yan Xin's eyes finally stopped on the material major!

This research direction is a good choice!

Yan Xin looked it up carefully, and found that the research in the field of materials is more mixed than other majors, and there are countless journals that include papers!
And the most famous top journal in materials science is Nature!
In addition, there are Applied Surface Science, Materials Letters, Carbon, Journal of Alloys and Compounds, etc., which are the most influential materials journals in the world.

Like rubber, plastic and ceramics, in terms of non-metallic materials, Longxia is still far ahead in the international research field!

Take ceramics as an example: the earliest unearthed in Longxia is the original celadon about 4200 years ago!However, it is only an intermediate product of the transition from ceramics to porcelain.

However, even though celadon is not real porcelain, it has a long history. According to historical records, celadon was already very mature in its production technology as early as the Shang and Zhou dynasties!

Primitive celadon has a history of more than 1000 years in Chinese history. Although compared with later generations of porcelain, the technology is insufficient, but as a starting point, primitive celadon also played an important role in the development history of Chinese ceramics. The development of ceramics has played a role that cannot be ignored.

Pottery really emerged in Jingdezhen, Jiangxi Province during the Han Dynasty.Jingdezhen ceramics are famous for their white porcelain, known as "white as jade, bright as a mirror, thin as paper, and sound like a chime".Porcelain is excellent in quality, light in shape and diverse in decoration.

In later generations, in order to praise Longxia's porcelain, foreign countries also defined Longxia's English: china and another Chinese translation as: porcelain!
These materials and sayings show to a certain extent that Longxia's ceramics, that is, non-metallic materials, are still recognized by the world!
Compared with non-metal materials, Long Xia's research in the field of metal materials pales in comparison internationally.

In today's era, metal materials are widely used, such as the wings of airplanes, the engines of automobiles, the whole body of ships, large mechanical equipment and so on.

It can be said that metal materials are ubiquitous in our lives.

Once the number of metal materials meets the requirements, people begin to do further research on their comprehensive properties.

Therefore, the hottest thing nowadays is how to improve the properties of metal materials such as corrosion resistance, high temperature resistance, wear resistance, and thermal stability.

Many researchers have proposed methods such as surface modification and changing the phase structure to change the comprehensive properties of metal materials from the macro and micro levels of metal materials.

But the results are not very ideal.

Yan Xin immediately felt that this was a big breakthrough!
If he really develops a new type of metal material that is internationally leading, it will be a qualitative change for himself, and even for Long Xia!

Looking at the data jumping on the screen, Yan Xin naturally had the next learning goal in mind!

That's college basics and metals!
