Live broadcast of my blind date with Miss Dai, sister Zhou was arrested

On the barrage in the live room.

The fans of Dai Xiaomei immediately began to curse at those black fans.

Although those people are all from Weibo.

But when it comes to things like swearing, the group of people watching the live broadcast are more capable.

After a while

On the barrage in the live broadcast room, most of the black fans from Weibo were scolded and dared not speak up.

remaining people,

It was too late to send a message to refute, and was banned by the housing management.

"Okay, I'm here today."

Dai Xiaomei saw that the time was almost up, so she said to the water friends.

The water friends were naturally ridiculed when they saw this.

You are not stupid.

This woman is clearly a husband and slave, and she is obviously going to find her husband.

"Old woman, you are too much!"

"It's hammered!"

"Hmph, falling in love really affects the live broadcast, what time is it?"

"It's not that old woman who stays with us all day anymore."

"If you have a boyfriend, forget about your brother."

"That's right!"

"Sad."

"Take it off and go for a while."

"Oh, I hate Professor Ye."

"I miss the days when Xiao Yuan was here."

"Hahahaha, I think Mr. Dai can rest. Didn't Professor Ye broadcast live today?"

"exactly."

"That's a great suggestion."

"I thought so too, haha!"

"........."

Looking at the news on the barrage, Dai Xiaomei is not feeling well.

These guys, why don't you be so direct!

"You people."

Dai Xiaomei said angrily: "My husband is replacing me and Xiaoyuan, and I will broadcast it occasionally, do you understand?"

"It doesn't matter, I'm off work, I'm off work, I'm going off work!"

"goodbye!"

After saying these two words, little girl Dai didn't say anything, and decisively downloaded the broadcast.

What an international joke!

She won't stay and continue the live broadcast.

Watching Xiaomei decisively downcast.

The water friends in the live broadcast room did not say anything other than a few complaints.

........................

After the live broadcast, the little girl naturally went to remove her makeup and wash her face.

After she finished washing, it was already an hour later.

turn on your phone,

She saw a lot of news on it.

Most of them are from acquaintances.

Yu Shuang, sister Zhou and others simply called directly.

Opening one at random, she listened to the voice inside, and it was Wang Boluo.

"Boss Dai, check Weibo quickly, Professor Ye has posted on Weibo!"

"My God, what are you doing, big sister? (Zhao's)"

"Why don't you reply to the message!"

"The entire Weibo has exploded now, and your husband's Weibo is the number one most searched!"

Look at these messages.

Dai Xiaomei was dumbfounded.

She quickly opened Weibo and read it.

as predicted.

Ye Tian's long Weibo article is now the number one most searched Weibo article.

【What is a real feminist fork】

Just by looking at the title, Dai Xiaomei knew it.

My boyfriend must have done another shocking thing.

Otherwise, such a thing would not have happened.

Thinking about it also makes me feel helpless.

Even those celebrities in the entertainment industry have to work hard to be in the trending searches.

In the end, when I came to my man, it was as if I was eating and drinking, it was so easy.

People are really different.

PS: Ask for flowers, ask for evaluation tickets, ask for rewards, ask for automatic subscription! .

Chapter 282 Submarine Pump Jet Propeller (for automatic subscription)

Dai Xiaomei quickly forwarded Ye Tian's Weibo.

For her, this multiple-choice question is not difficult.

On one side are those inexplicable women's rights, and on the other side are their own men.

Unless Little Sister Dai is crazy, how could she stand by them.

But she still went to ask Ye Tian specifically.

"Husband, do you want to post another Weibo to explain this incident?"

Dai Xiaomei asked Ye Tian.

Ye Tian frowned.

Getting ready to speak.

【Ding!God-level selection task trigger]

Ye Tian was taken aback by the sudden voice in his mind.

[Option 60.00: Send a microblog to apologize to female compatriots, and get [-]% of all female favorability. 】

[Option [-]: Ignore the clamor for women's rights and reward submarine pump jet propulsion technology]

What the hell!

! ! ! !

! ! ! !

Ye Tian was stunned for a moment.

To know.

Nuclear submarines are usually divided into strategic missile nuclear submarines and attack nuclear submarines.

The former uses ballistic missiles as its main weapon and is used to strike strategic targets on land. It is the main component of the national strategic 307 nuclear force.The latter uses torpedoes and tactical missiles as the main weapons to attack surface ships, submarines and important ground targets, and is an indispensable combat force for ocean control.

Because of participating in the nuclear propulsion project before, Ye Tian has a deep understanding of many equipment of nuclear submarines.

According to the information he has read.

A submarine propelled by a pump jet is compared with a submarine propelled by a large skewed propeller.

The biggest advantage is that it can greatly reduce the radiation noise of the submarine propeller and increase the low-noise speed of the submarine.

Take the Yingjiang "Sea Wolf" class attack nuclear submarine as an example. The maximum underwater speed of this submarine is more than 35 knots, and the maximum speed can even reach [-] knots.

The low-noise speed at 30 meters underwater is greater than [-] knots, and the radiated noise is close to the noise of the ocean environment. It is officially called the quietest and fastest submarine in the world by Eagle Sauce.

Ye Tian is very aware of the threat of submarines of this level.

At that time, in order to study my country's nuclear propulsion, he specifically consulted a batch of materials.

In addition,

The military also provided him with some information (acci).

of course.

Mainly nuclear submarines.

Nuclear submarines have powerful attack power, unique concealment and mobility, can stay away from the base for a long time, and have the ability to cooperate with other forces in the naval formation to carry out various combat missions.

Therefore, it has always been the focus of fierce competition among the naval powers in the world.

However, once a nuclear submarine is exposed, it will lose its inherent advantages, be easily tracked and attacked by the enemy, and its survivability will be greatly reduced.

With the rapid development of acoustic detection technology, how to reduce radiation noise and reduce the probability of being discovered by enemy sonar has become a key research topic of nuclear submarine technology.

If Ye Tian remembered correctly.

Propeller noise is one of the main noise sources of nuclear submarines.

and,

Because the propeller is exposed outside the hull, it is easy to radiate noise into the water.

At low speed, the low-frequency line spectrum noise of the propeller has low frequency and high intensity, and can radiate to far sea areas.

At medium and high speeds, the rotational noise increases with the speed, and gradually surpasses the low-frequency line spectrum to become the main noise of the submarine.

Once the blades of the propeller produce cavitation, the noise will be greatly enhanced, and the propeller noise will become the main noise of the submarine.

therefore,

To reduce the noise of a nuclear submarine, the noise of the propeller must be reduced first.

In addition, in order to give full play to the combat effectiveness of nuclear submarines, attack nuclear submarines are gradually developing in the direction of high speed and quietness.

The maximum underwater speed of the new generation of quiet attack nuclear submarines exceeds [-] knots, and the low-noise speed reaches [-] knots.

This poses a new problem for the design of the propeller: if the traditional single seven-bladed large-slope propeller is still used for propulsion, due to the excessive load on the propeller, the blade will cavitate in advance, which will reduce the low-noise speed of the nuclear submarine. .

If the blade area of ​​the propeller must be increased in order to delay the generation of cavitation, the efficiency of the propeller will decrease and the noise will increase.

The information that Ye Tian saw at that time showed that.

In order to find a suitable low-noise propulsion method for the new generation of nuclear submarines, countries around the world have spent a lot of manpower and financial resources, carried out extensive and in-depth research and experiments, and finally formed two different solutions.

One is to use two sets of seven-blade large skewed propellers to divide the total propeller load into two. For example, this propulsion method was adopted on the "Kursk" nuclear submarine.

The other is a brand-new pump-jet propulsion method, which is used by all newly built nuclear-powered attack submarines in European and American countries.
