Chapter 2093 Underwater World
In fact, strictly speaking, this dish is Jiangxi cuisine.However, because Gan cuisine does not have a complete cuisine, Hunan people naturally classify this dish as Hunan cuisine.

Anyway, people all over the world know that Sichuan cuisine is spicy and Hunan cuisine is extra spicy.As for the taste of Jiangxi cuisine, those who have never been there will know.

I don't know why?With the development of the times, women not only have more and more tempers, but also have more and more serious tastes.

Anyway, men in northern Xinjiang can't eat spicy food as much as women.For example, the four women who ate today, although Jing Jing and Rose also like spicy food.However, the degree of acceptance is obviously different.

For example, the chili fried chili, the two of them will never touch it.But Ye Qianqian and Liu Yifei are happy.

Especially Liu Yifei, although her personality is always so weak, but when the chili is in her mouth, it seems that she doesn't feel it.Looking at the rose is also dumbfounded.

Now Yifei is the director of the government office and has always been with the government.She is on the same level as Ye Qianqian, but because both of them are too young, when Ma Rong and the others retire, their qualifications and age will naturally not be able to succeed them.

After Liu Yifei came back from the United States, her personality changed a lot, especially after she married Ye Feng, she became more cheerful.

Of course, her cheerfulness refers to her mood. If she is made to be as pungent as Ye Qianqian, she will not be able to do it.

When Ma Rong and Zhao Linger were assigned, they had already thought about it, and they each found someone with a big difference in personality to complement each other.

Such a restrained Liu Yifei became the secretary of the carefree Zhao Linger.

Naturally, the women couldn't drink like the men, and they just asked for a bottle of pure sorghum as a token.Two or two drinks per person is almost the same as not drinking for them.

It's just that after drinking a glass of wine, Song Danning's eyes suddenly turned red, and he insisted on asking for another bottle.

Among the few people, Song Danning felt the most pressure in his heart. He left his hometown and came here for love.

In the end, my husband didn't see her once a year on a remote southern island.

The moment she walked out of the house, the house in the capital had nothing to do with her.

Although her father-in-law and mother-in-law are very kind to her at present, and her work is relatively smooth.But how long will this day last?
When did Liu Junken change jobs?It is still unknown whether they will change jobs. Could it be that the two of them have been going on like this?until retirement?
Every time Song Danning thought of these things, he felt very wronged.He even thought about joining the army, but Liu Junken's current level is not high enough to join the army.

Seeing that Song Danning was uncomfortable, several other people were also uncomfortable.Don't talk about Jingjing, she used to have a son with her, but now her son is gone too.She said she was a married woman, but they separated without even a wedding photo.

Rose is similar. Zhambul has been in neighboring countries, and both daughters have gone to the capital. She lives alone in the dormitory building, so she is naturally lonely.

Seeing that everyone was a little depressed, Ye Qianqian quickly waved her hands:

"Okay, okay, there are still so many things that need to be done, don't always think about the relationship between children, as if we can't live without men."

Ye Qianqian's words really worked, and everyone soon cheered up.

In fact, Ye Qianqian still has emotions about the job, not because she doesn't like the job, but because she thinks the current practices in the city are too conservative.

According to the current plan, the scale of Junken City will stop here, and in their generation, they only need to keep the current situation.

In fact, Rose and Jingjing are more supportive of the meaning of the city.After all, it is located in the border area, and all aspects will be restricted.

If a modern metropolis is built in such a place, there will definitely be many unsolvable things.

But Ye Qianqian and Liu Yifei don't think so. Only when they are adjacent to the border can they have development prospects. Take a look at Shenzhen and Guangzhou. Which of them didn't have their current achievements because of the coast?

The biggest trade in these cities is foreign trade. Although Junken City is not facing the sea, its borderline is so long, so it naturally has all the conditions for foreign trade.

Moreover, the current foreign trade volume of Junken City is really not comparable to that of ordinary places.Even the coastal cities do not need to give way.

Moreover, compared with the export dividends that rely on resources and cheap labor over there, the output of Junken City is entirely technical products.

The flagship products, automobiles and chips, are at the top of the world.In such a place, what reason is there to control the scale?
Song Danning was a little silent about the debate between them.She is not a person without political intelligence.It's just that the mind has not been fully immersed in the work.

After arguing for a while, there was no result, and several people dispersed.After all, they are people with regular work and rest schedules.

Moreover, the government units have always retained a tradition, that is, group running exercises every morning.

After all, the founders and inheritors of this city are all military cultivators with red seedlings, although because of the needs of the city, they can no longer go to military training with guns every year.

But many traditions must be continued, not only for others to see, but for future generations not to forget their identities.

In the South China Sea, Liu Junken and his submarines are performing missions. The situation in this sea area has always been complicated.

From time to time, ships and submarines break into this area to carry out various reconnaissance or provocative activities.

In addition to patrolling surface ships, our side will also send submarines to patrol. After all, surface ships sometimes cannot detect the situation on the bottom of the sea.

At this time, Liu Junken had been promoted to the deputy captain of the submarine because of his outstanding performance.After all, he graduated from the most excellent military academy, and he has outstanding performance in all aspects. For such talents, the fleet will naturally have to reuse them.

The captain is an old man in the South China Sea, and he is very familiar with this area of ​​the sea, but because of his age and education, he has lost the chance of promotion, and the boarder is considering his retirement.

As an officer, very few are willing to retire, especially at a certain rank.After all, I have been in the army for so many years, and I have fully integrated into this kind of life.

Once you move to another place, there is really no way to integrate into that slow-paced life in a short period of time.

Especially because of professional reasons, it is difficult for cadres transferred from the military to obtain ideal positions. Many outstanding cadres end up in obscurity. After all, they are two completely different systems.

Therefore, the captain has not been in a good mood recently. He has a straight temper, and it can be seen on his face that he is in a bad mood. The soldiers try to avoid him as much as possible.

In the command cabin, Liu Junken was also concentrating on observing the bottom of the sea.This is already at a depth of 600 meters underwater.

At present, the submarine that can dive the deepest known in the world is the Japanese submarine Kaiko. Its diving position is at a depth of 10975 meters at the bottom of the deepest trench in the world, the "Mariana Trench".

The world's first nuclear submarine was the "Nautilus" of the United States. On January 1954, 1, it began its trial voyage for the first time, which announced the birth of nuclear-powered submarines.

There are 6 countries in the world that publicly claim to have nuclear submarines, namely: the United States, Russia, the United Kingdom, France, China, and India.

Among them, the United States and Russia have the most nuclear submarines.The emergence of nuclear submarines and the application of nuclear strategic missiles have brought the development of submarines into a new stage.Nuclear submarines equipped with nuclear strategic missiles are an underwater deterrent nuclear force.

In the eyes of those Westerners, Chinese submarines do not have the slightest deterrent power, and there is nothing extraordinary in terms of diving depth or firepower attacks.

But what they don't know is that the Chinese navy has many high-tech means that are difficult for them to detect, but we are used to keeping a low profile.

Now that we can produce all kinds of special steels in-house, and we have made a leap in engine research, why is it so simple on the surface?
Submarines are very mysterious to most people. In their subconscious minds, they think that it is like a sniper with superior ability, who can lurk somewhere for a long time, observe the enemy's situation through a telescope, and once the target is found, Just kill him decisively.

In fact, this is completely a cognitive error.

You must know that the visibility on the bottom of the sea is extremely low, and the lights have no effect at all, and the lights equipped on submarines are basically used on the sea surface.

In other words, at the bottom of the sea, even if you turn on the light with the strongest light-gathering performance, you will not be able to see the situation outside.

Some people will definitely be unconvinced when they say this, and they will use the example of those who drive the sea to catch precious seafood underwater, because those people all have lights on their heads.

But don't forget, how deep can a personal dive go?Wherever they can go is where the sun shines.You can see blurry shadows even without a light.

But once in the deep sea, the situation is completely different, just like driving in a thick fog, how far can you see?

What's more, it is hiding in a behemoth wrapped in three layers of steel plates.It's no different than a blind man.

To put it bluntly, submarine navigation is like a blind man walking, but the blind man relies on a cane in his hand, while the submarine relies on sonar detection.

The term sonar must be unfamiliar to everyone. In fact, there is a creature that everyone is familiar with, that is, bats.

Because this kind of creature is used to being active at night, its vision has long been degraded and useless, that is, it is used to feel the sea, sky and night.

Everyone must be wondering, since they can't see anything, how can they not hit the tree?This is the magic of sonar.

Bats can make a sound, which is ultrasonic waves, which are inaudible to our human ears. This sound wave will automatically reflect back when it touches something, allowing bats to accurately avoid obstacles.

Everyone must be wondering, this thing can avoid one or two obstacles, what if there are more?

But think about it, have you ever bumped into a bat flying in the jungle and mountains?

Also, their food is all kinds of flying insects, and even mosquitoes can be caught by sonar. Do you think that this system will be damaged by your eyes?
People emit sound waves from their throats, receive reflections with their ears, and quickly reflect them to their brains, so they can accurately catch small flying insects like mosquitoes, so they don't need eyesight at all.

But don't think that a submarine can run rampant on the bottom of the sea with sonar, there are many factors.

With the help of radar and sonar systems, submarines can avoid underwater obstacles such as reefs very well.

But in fact, the world under the sea is not as peaceful as people think. Submarines also need routes to sail in the sea.why?

First of all, for our earth, the environment of the entire earth is complex and changeable.

Temperature differences between the north and south poles and the equator, the movement of monsoon ocean currents, submarine plate movements, volcanic eruptions, etc. will all cause differences in the temperature and salinity of seawater.

The temperature and salinity of surface seawater and deep seawater in the same water area are also different.

Generally speaking, the upper seawater has high temperature, low salinity, low density and low buoyancy, and the lower seawater temperature has low salinity, high density and high buoyancy. At the junction of two water layers with different densities, this layer of water is generally called the climatic layer.

The climatic layer has a positive effect on underwater communication and the concealment of submarines, so submarines generally sail in the climatic layer.

However, in some sea areas, due to the influence of ocean currents, undercurrents and other factors, the cline layer is abnormal, which makes the buoyancy of the upper seawater greater than that of the lower seawater.

When the submarine enters such abnormal waters from the normal climatic layer, the buoyancy of the submarine suddenly decreases, which will cause the submarine to dive passively.

This process is relatively fast, and it is too late for general submarines to increase buoyancy through drainage or other means.

Often it will dive deeper and deeper, and finally be crushed and crushed by the huge pressure of the seabed, and the boat will be destroyed.

This phenomenon is that the submarine falls deep (the abnormal phenomenon of seawater density in the climatic layer is called sea cliff).Throughout the history of submarines, only the 372 boats of our army may have succeeded in self-rescue in the deep-falling accidents caused by sea cliffs, which can be called a miracle.

Of course, when it comes to the buoyancy change of sea water, we have to mention a famous place.

There is a seabed of water in the sea that can produce a large amount of methane, and the methane is released into the seawater to form a boiling phenomenon on the sea surface.

The buoyancy of such sea water is greatly reduced, and many shipwrecks occurred after ships arrived in this water area. This place is the Bermuda Triangle.

In addition to this phenomenon in the sea, there is also a great threat to submarines.

Turbulence is caused when high tides, warm currents, etc. violently hit obstacles in the shallows or enter deep water through narrow straits.

The difference from ocean waves is that this turbulence is called a submerged wave under the sea surface, and the submerged wave has an amplitude ranging from tens of meters to hundreds of meters, and a wavelength ranging from hundreds of meters to tens of thousands of meters.

If a submarine encounters a submarine wave, just like a ship on the sea encounters a wave, it will be driven up and down by the wave.

Of course, if it is carried up by the diving waves, it is better to throw it to the surface of the sea at most. If it is carried down and falls deep or hits a rock, it will be over.

Now surveyed from satellites, there are such submarine waves in the Malay Peninsula and the Sulu Sea of ​​the Philippines, which appear about once every 12 hours.

Of course, in addition to these oceans, there are also various internal waves similar to submarine waves caused by many factors such as the atmosphere and plate movement, which are also fatal to submarines.

Therefore, marine surveys are very important, and it is understandable for submarines to plan routes to avoid known dangers in the sea.

Therefore, even in the sea, submarines need to follow the route, which is similar to airplanes.
