Chapter 2288 Undersea World
In fact, strictly speaking, this dish is Jiangxi cuisine. However, because Gan cuisine does not have a complete dish, Hunanese people naturally classify this dish as Hunan cuisine.
Anyway, people all over the world know that Sichuan cuisine is spicy and Hunan cuisine is spicy. As for what Jiangxi cuisine tastes, people who have never been there know a shovel.
I don’t know why? With the development of the times, women not only have a bigger temper, but also have a heavier taste.
Anyway, men in northern Xinjiang are relatively unable to eat spicy food for women. For example, the four women who were eating today, Jingjing and Rose also like to eat spicy food, but they are obviously different in acceptable terms.
For example, the two of them will never touch this hot pepper. But Ye Qianqian and Liu Yifei are willing to accept it.
Especially Liu Yifei, although her personality is always so weak, it seems that she doesn't feel anything when she sees it. Rose is also stunned.
Now Yi Fei is the director of the government office and has been 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 take over their class.
After Liu Yifei returned from the United States, her personality changed a lot, especially after marrying Ye Feng, she became cheerful.
Of course, her cheerfulness refers to her mood. If she becomes as stingy as Ye Qianqian, she will not be able to do it.
When Ma Rong and Zhao Linger were assigned, they thought about it and found one with a big personality difference to complement each other.
Such a restrained Liu Yifei became the secretary of Zhao Linger, who has a carefree personality.
Naturally, a few women could not drink like men, but they symbolically asked for a bottle of sorghum. One person had more than two taels of wine, which was similar to not drinking.
But after drinking a glass of wine, Song Danning's eyes suddenly turned red and she insisted on asking for another bottle.
Among the few people, Song Danning was under the greatest pressure, and he left his hometown and came here desperately for love.
As a result, my husband was seen on the distant southern island not once a year.
The moment she walked out of the house, the home in Beijing had nothing to do with her.
Although her parents-in-law are very good to her and her work is more comfortable, how long will it take to last such a day?
When will Liu Junken change his career? Whether he will change his career is an unknown. Did the two of them keep going like this until they retire?
Every time Song Danning thinks of these things, he feels so aggrieved. He even has the idea of following the army, but Liu Junken's level is not enough at present and he cannot join the army.
Seeing Song Danning feeling uncomfortable, the other people were also uncomfortable. Just stop talking about Jingjing. She had a son with her before, but now her son has left. She said she was a married woman, but she separated without even a wedding photo.
The roses are similar. Jiangbuer has been in the neighboring country. Both of his daughters have gone to the capital. She lives alone in the dormitory building, so she is naturally lonely.
Seeing that everyone was feeling a little depressed, Ye Qianqian quickly waved her hand:
"Okay, OK, there are so many things to do now. Don't always think about the relationship between children. It seems that we can't live without a man."
Ye Qianqian's words really worked, and everyone was excited soon.
In fact, Ye Qianqian is still emotional about work. It’s not that she doesn’t like this job, but that she thinks the current approach in the city is too conservative.
If we follow the current plan, the scale of the military reclamation city will end here. By their generation, we just need to maintain the current situation.
In fact, Rose and Jingjing support this meaning in the city. After all, they are located in the border area and are subject to restrictions in all aspects.
If a modern metropolis is built in such a place, there will definitely be many things that cannot be solved.
But Ye Qianqian and Liu Yifei don’t think so. Only by adjoining the border can there be development prospects. Look at Shenzhen Stock Exchange and Guangzhou, which one has achieved its current achievements because of the coastal areas?
The biggest trade in these cities is foreign trade. Although the military reclamation city is not near the sea, its border line is so long that it naturally has all the conditions for foreign trade.
Moreover, the current foreign trade volume of Military Reclamation City is really not comparable to that of ordinary places. Even coastal cities do not need to make too much money.
Moreover, compared with the export dividends that rely on resources and cheap labor, the output of Junken City is completely technical products.
The flagship products of automobiles and chips are even at the top of the world. In such a place, what is the reason to control the scale?
Song Danning was a little silent about the debate between them. She was not a person without political wisdom. She was just that she had not been able to fully immerse herself in her work.
After a while of argument, there was no result, and a few people parted. After all, they were all people with relatively regular schedules.
Moreover, the government agencies have always retained a tradition, which is group exercises every morning.
After all, the founders and inheritors of this city are all well-known military reclamationists. Although due to the needs of the city, they can no longer go to military training with guns every year.
But many traditions must be continued. This is not only for whom to show, but for future generations not to forget their identities.
In the South China Sea, Liu Junken and his submarines are carrying out missions, and the situation in this sea area has always been relatively complicated.
From time to time, ships and submarines break into this area and conduct various reconnaissance or provocation activities.
In addition to patrolling surface ships, we will also send submarines to cruise. After all, surface ships sometimes cannot detect the situation under the sea.
At this time, Liu Junken had been promoted to the deputy captain of this submarine because of his outstanding performance. After all, he graduated from the best military academy and performed very well in all aspects. For such talents, the fleet naturally had to reuse them.
The captain is an old Nanhai and knows this area very well. However, due to age and education, he lost the opportunity for promotion. He is considering his retirement issues.
As an officer, few people are willing to retire, especially to a certain level. After all, after struggling in the army for so many years, they have completely integrated into such a life.
Once you transfer to a local area, you really can't integrate into that slow-paced life in a short period of time.
Especially due to professional reasons, it is difficult for military-to-military cadres to obtain ideal positions. Many outstanding cadres end up missing. After all, they are two completely different systems.
Therefore, the captain has not been in a very good mood recently. He is straightforward and in a bad mood, he can tell from his face that the soldiers try their best to avoid him.
In the command cabin, Liu Junken was also observing the seabed with all his attention. This place was already 600 meters underwater.
The most well-known submarine in the world that has been researched to dive is the Japanese kaiko submarine. Its dive is 10,975 meters deep at the bottom of the "Mariana Trench" in the world.
The world's first nuclear submarine was the US Nautilus. Its first trial voyage began on January 24, 1954, and it announced the birth of a nuclear-powered submarine.
There are six countries in the world that publicly claim to own nuclear submarines, namely: the United States, Russia, Britain, France, China, and India.
Among them, the United States and Russia have the most nuclear submarines. The emergence of nuclear submarines and the use of nuclear strategic missiles have brought the development of submarines into a new stage. Nuclear submarines equipped with nuclear strategic missiles are a nuclear force for underwater deterrence.
In the eyes of those Westerners, Chinese submarines have no deterrence at all, and there is nothing extraordinary in terms of diving depth or fire attack.
But what they don’t know is that the Chinese navy has many high-tech means that they are difficult to detect, but we are used to being low-key.
Now that our various special steels can be produced by themselves, we have already made a leap in engine research. How could it be as simple as it seems?
Submarines are very mysterious to most people. In everyone's subconscious, they think it is like a sniper with superb abilities, who can lurk somewhere for a long time, observe the enemy situation through a telescope, and once they find the target, they will decisively kill them.
In fact, this is a completely cognitive mistake.
You should know that the visibility of the seabed is extremely low, and the lights do not play any role at all. The lights equipped by 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 strong light concentration performance, you will not be able to see the situation outside.
Someone will definitely be dissatisfied with saying this and will show the examples of sea-driven people catching precious seafood underwater, because those people have lights on their heads.
But don’t forget, how deep can an individual dive? Where they can reach are places where sunlight can shine. Even without using lights, you can see the shadow of Mohu.
But once you reach the deep sea, the situation is completely different. Just like driving in a heavy fog, how far can you see?
What's more, he was hiding in a giant wrapped in three layers of steel plates. He was not at all different from a blind man.
To put it bluntly, submarine sailing is like a blind man walking on the road, but blind man relies on the cane in his hands, while submarines rely on sonar detection.
Everyone must be a little unfamiliar with the statement of sonar. In fact, there is a kind of creature that everyone is familiar with, which is bats.
Because this creature is used to moving at night, its vision has long been deteriorated and has no effect, which is used to feel the sea and the sky.
Everyone must be wondering how they can't hit the tree since they can't see anything? This is the wonderful use of sonar.
Bats can make a sound, which is ultrasound, which cannot be heard by our human ears. When this sound wave touches something, it will automatically reflect back, allowing the bats to accurately avoid obstacles.
Everyone must be wondering, one or two obstacles can avoid this thing, what if there are too many obstacles?
But think about it, have bats ever hit the jungle and mountains?
Also, their food is all kinds of flying insects, and even mosquitoes can be captured by sonar. Think about it, will your eyes be bad for that system?
People can accurately catch small flying insects like mosquitoes, so they do not need vision at all.
But don’t think that submarines can run rampant on the seabed with sonar, and there will be many factors.
With radar and sonar system, submarines can avoid underwater obstacles such as reefs.
But in fact, the world under the sea is not as calm as people think. Submarines also need routes to navigate in the sea. Why?
First of all, for our earth, the entire earth's environment is complex and changeable.
The temperature difference between the north and south poles and the equator, the movement of monsoon currents, the movement of the seabed plates, the eruption of volcanic eruptions, etc. will cause different temperature salinity of seawater.
The temperature salinity of the surface seawater and deep seawater in the same water area also varies.
Generally speaking, the upper seawater temperature is high, salinity, low density, low buoyancy is low, and the lower seawater temperature is low, salinity is high, high density is high, and buoyancy is high. At the intersection of two water layers with different densities, this water area is generally called a jumping layer.
The jumping layer has a positive effect on underwater communications and the concealment of submarines, so submarines generally sail in the jumping layer.
However, some sea areas have abnormal jump layer due to factors such as ocean currents and undercurrents, which makes the upper seawater buoyancy larger and the lower seawater buoyancy smaller.
When the submarine sails from the normal jumping layer into such abnormal waters, the submarine's buoyancy suddenly decreases, which will lead to the submarine's passive diving.
This process is relatively fast. Generally, it is too late for submarines to increase buoyancy through drainage or other means.
Often, the deeper the dive, the deeper it will eventually be flattened and crushed by the huge pressure on the seabed, and the boat will be destroyed and people will be killed.
This phenomenon is the submarine's deep drop (the abnormality of the sea water density in the jump layer is called a cliff in the sea). Looking at the entire submarine's history, the deep drop accident occurred due to cliffs in the sea, which may only be the 372 boats of our army successfully rescued themselves, which is a miracle.
Of course, when it comes to the change in seawater buoyancy, we have to mention a famous place.
There is a water area in the sea that produces a large amount of biogas under the sea, and the biogas is released into the sea water to form a boiling phenomenon on the sea surface.
The buoyancy of such sea water is greatly reduced. After the ship arrives in this water, many shipwrecks occur, and this place is the Bermuda Triangle.
In addition to this sea, there is another phenomenon that poses great threat to submarines.
Turbulence is caused when high tide and warm currents violently impact obstacles in shallows or when entering deep water through narrow straits.
Unlike waves, this turbulence is called submersible waves under the sea surface, and the amplitude of this submersible wave ranges from tens of meters to hundreds of meters, and the wavelength ranges from hundreds of meters to tens of thousands of meters.
If a submarine encounters submersible waves, just like a ship on the sea surface encounters a wave, it will be driven by the waves to float up and down.
Of course, if you are carried up by a diving wave, it is best to throw it to the sea at most. If you are led down and fall deep or hit the reef, it will be over.
There are now such submersible waves in the Malay Peninsula and the Sulu Sea in the Philippines, which are detected from satellites, and they occur about every 12 hours.
Of course, in addition to these oceans, there are various internal waves similar to submarine waves caused by many factors such as atmosphere and plate movement, which are also fatal to submarines.
Therefore, ocean surveying is very important, and planning routes to avoid known sea dangers is understandable for submarines.
