In the cave of the Lianyun shipyard, the hull of a brand new submarine has been completed.
With a double titanium hull, they aim to dive to a depth of 500 meters and be able to cruise at a depth of 350 meters.
The latest diesel generators and battery packs, propulsion systems, operating system detection systems, life support systems have been completed.
Preparing for sea trials.
The German-made submarine, named Xia-class 001, has undergone several sea trials and refits, and has been officially handed over to the Navy.
However, the mapping of nautical charts is being carried out in the Yellow Sea.
Dive to a depth of 250 meters.
This is more than a hundred meters deeper than the depth of Japanese submarines, and it is much quieter.
Japan's sonar is backward, and it has always been thought that Chinese submarines will not dare to go to sea.
In fact, it was already locked with torpedoes under them several times.
It's just that there was no attack.
The new submarine is a little smaller than the German-made one.
It's not that it can't be built, but it is thought to be too big, which is not good for deep diving and speed.
As for the attack power, it was achieved by the improvement of torpedoes.
The development of submarines in Japan is in the opposite direction, and their submarines are equipped not only with cannons, but also with seaplanes.
It's huge, but the downside is that you can't dive deep, and the speed is so slow.
The new submarine removed all the mess outside the hull and took on the shape of a droplet.
The hull is made of high-volume casting, which reduces anchoring and welding. to ensure the smoothness of the hull.
This is much better than a German submarine full body rivet.
It's just that the so-called "large volume" is relative to the summer class 001.
The foundry is still being remodeled, and the next submarine will be even smoother.
The shipyard is also conducting welding experiments, and the Xinmin Research Institute has a great advantage in this regard, and another advantage is to carry out a second treatment of the appearance of the casting.
This is the technology brought by the traditional Chinese ceramic craft and the minting of Xinmin coins, and it has rich experience.
As long as titanium alloy materials can withstand high temperatures and do not deform, they can be completely covered with a layer of ceramic.
Of course, not this one.
The Institute of Materials is experimenting with such an alloy formulation.
The Institute of Electronics and the Institute of Physics are working on lasers that can cut castings.
Because it's more accurate than any other cutting method, and it does the least damage to the casting.
The precision machine tool has also been upgraded again because of the use of computers, and precision manufacturing is developing by leaps and bounds.
Because as long as this aspect is improved, it is the overall improvement.
The bicycles that are now exported from the United States are just imitations, and they are still stupid and stupid, just because the materials and processes cannot be reached.
The General Motors plant in the United States saw the Chinese acceptance standards brought back by the business group and said that it was too harsh to be done.
Emissions, in particular, they see as a false barrier that China does not want to buy from the United States.
The Americans, who came to engage in intelligence, discovered that all the construction sites in China were military personnel, although they were in the name of companies.
Even the driver is also armed, heavily guarded, and can't get in at all.
Even scrapped vehicles are recovered, and these soldiers pick up a screw on the ground.
This makes the site exceptionally clean.
This habit of the Chinese is very unaccustomed to the Americans, who have always been big-eyed.
Their cutlery was made of wood, and after eating, everyone did not have a grain of rice in their bowls.
All garbage is sorted and pulled away.
The fallen leaves are buried in the grass by the sanitation workers, and they don't get tired of doing this every day.
If you don't do it, someone will whisper in your ear.
If you throw a piece of paper, it will involve world peace, and you say that it is not terrifying.
Lianyun City is the most beautiful seaport.
Is it just that the Chinese don't bask in the sun on the beach?

They plant trees on the beach, all kinds of trees and grasses.
This makes the whole coast look green.
Not only trees, but also various mosses and ferns.
They looked for species that were tolerant to salinity and flooding, and even paid Americans to bring them back from the Americas and beyond.
A lot of Americans who come to China are doing this kind of business.
They say that the Chinese love trees and that the clothes they wear in their troops are the color of trees.
American crew members are often bullied in China, the Chinese are too mean, and when you fight with a person, you must always prevent their small movements, and you must also pay attention to whether there are other Chinese around.
Because you will be inexplicably put down by the other party's companions.
They don't have rules at all, whether it's male or female.
But if you are polite and follow Chinese rules, the Chinese will be very kind.
Also, in China, don't mess with the old man and women, the status of women in China is ridiculously high.
It is said that the supreme leader did not even care about political affairs for the sake of his wife and children.
Chinese women are also very tough, and you have to be careful when you meet a woman in military uniform.
Because she definitely has the strength to put you down.
China is an ignorant but advanced country.
Their trains are very fast.
From Lianyungang to Xi'an, it takes half a day to arrive.
But if you want to see the scenery, you won't be able to see it in a few years, because you can't see the scenery from Xi'an to Wuhan, trees, trees, all trees.
Even the middle of the bridge was planted with soil.
Their cities and railways do not have dense power poles.
But there is absolutely electricity in the house.
Is there just a city in China?
A lot of Americans who come to China say yes, but it's small, just a few old cities.
Lianyun City is a big city.
Wuhan is just a small city and a big rural area.
It's not that they don't have high-rise buildings, and some of them are much more beautiful and advanced than in the United States.
But it's not easy for you to see.
You've got to cut down those damn trees.
In May, Zhang Chun and Lizhi had to take a train to Kaifeng because the diversion of the Yellow River was about to be completed.
Song Qingling, Li Dazhao, and Mao Shishan accompanied Wu Peifu, who was in a wheelchair, to go a month in advance.
Where Sun Chuanfang stared.
The dam of the Yellow River was blown open by a small opening, and the river water rushed into the ancient Yellow River Road, and the water slowly rose on the wide channel.
This section of the levee was reinforced and needed to be blasted multiple times before the final diversion could be completed.
It takes up to two months, but before the rainy season arrives, it will definitely be completed.
By then, all that was left was the slick concrete aqueduct.
Only half of the aqueduct has been repaired, and the other half will have to wait for the water level of the old river to be lowered.
In addition to the diversion canals during the flood season, there are also water pumping stations during the dry season and the riverbed greening project exposed after the shrinkage of the Yellow River.
The diversion of the Yellow River is very smooth.
From Kaifeng to the boat, down the river, the Yellow River rises quietly in the grass and woods.
Although there is still sediment in the water, it is much less.
After the people of the environmental institute took the water and left it to stand, the sediment was less than one-twentieth.
This is already a tolerable level.
If Shanxi's domestic treatment is completed, water quality will continue to improve.
The boat is still a barge made in Shanxi, and Yan Xishan is still a little proud of this.
Song Qingling joked with him: "Baichuan, I don't think you should stay in Shanxi, it is better to go to Yantai to build a ship, anyway, coal and steel are also transported from Shanxi."

That's an ocean-going ship.
It's not about building small fishing boats. ” "Shanxi, the homeland is hard to leave."
Yan Xishan was eager to try, but he was still reluctant to Shanxi.
"It's hard to leave your homeland."
Sun Chuanfang is not polite: "You go to see my Xuzhou and Lianyun, your eyes are red." ” Jiang Fangzhen smiled: "Why is it yours, I, the district head, haven't left yet." ” "Go to your Shandong.
You haven't taken care of Longhai's affairs.
Sun Chuanfang laughed.
Zhang Chun stood behind Lizhi and helped Lizhi pinch her shoulders, the drastic changes in Lizi's body made her very uncomfortable, and even her bones were having problems.
After coming out, the diet and air were much worse than those of Daoxiangyuan.
"Yan Laoxi should go to Shandong, it's not far from Shanxi.
Mr.
Baili worked hard, Jianghuai Province was in ruins, and it was facing off across the river from the National Control Region, and Lao Jiang was now eyeing him.
It's just that Mr.
Baili didn't have a few days of stable life. ” Song Qingling smiled: "This suggestion is good. ” "Shandong, where are Cheng Qian and Zhang Tian staring, Lianyun and Jinan have air forces, although there are not many planes now, but they are all the establishment of a division.
Lianyun's aircraft factory was completed, and the output came up, so it would be good.
I'm not afraid of Zhang Xueliang and the little devils.
The military port in Weihai should be built.
The Wuhan shipyard could not build a large ship.
It is still possible to produce three or four ships a year of 5,000 tons.
Lian Yun is not in a hurry and lays a good foundation. ” In the sky, a helicopter flew over, and it turned out that Liang Sishun wanted to film the process of diverting the Yellow River, which was a major event for the whole country, and it would be a waste not to publicize it.
The photographer waved the TV flag a few times.
The helicopter hovered a little over the ship's petition and sped away.
Because the helicopter was too noisy, I was afraid that Zhang Chun would get angry.
Zhang Chun said with a smile: "This guy has a cannon hanging on it, and with the infantry, it is a nightmare for the armored soldiers of the Soviets." ” Several people watched the helicopter in the sky go away.
"That's it, it's a waste to give Liang Sishun this girl."
Song Qingling said with a smile.
"To limit it to combat is to have range. with the Army.
Long-range can only be an aircraft carrier, and the Germans, Great Britain and the United States are working on it, but I'm afraid it will take a few more years. ” Jiang Fangzhen smiled bitterly: "Mao Shishan and the guys from the Military Academy have been thinking about this thing for a long time, and now the dream has come true. ”R1152
