What Ye Duzheng drew was the 2 of diamonds.
Zhu Kezhen: "Sorry, I have the final say this time."
"I'll give you the pen, and you'll write the article." Ye Duzheng handed over the pen, turned around and left with a dark face.
……
"Xiao Huang, when the history of China's meteorology is written here in the future, you must not write about the current scene. Skip it, and you must skip it." Tu Changwang now turned his back to the crowd, with his arms stuck to the wall, and his forehead stuck to his arms , now no one can see what color his face is.
Huang Peichang: "Okay, Director Tu."
Tang Hua bared his teeth and smiled behind him: "Director Tu, you don't write the history of meteorology, but we will definitely write this story in the chapter on supercomputers in the history of computer development."
……
"Look, this is what the Shanghai Institute of Computer Science and the National Meteorological Administration have concocted."
Two days later, newspapers with weather forecasts were delivered to everyone's homes in Shanghai.
Zhou Xuan: "Is this a great achievement?"
Tang Hua: "If this forecast is accurate, it will be great."
Zhou Xuan: ...
Tang Hua: "Weather forecasting is actually like doing math problems. For example, if we predict what the weather will be like tomorrow, we only need to calculate where the clouds will float in the sky in 24 hours. There are 10 problems in total. But If you want to predict the weather in the day after tomorrow, you have to do 30 questions, and the weather in the day after tomorrow has to do 90 questions. For every extra day of calculation, you have to solve twice as many math problems. To predict the weather in 15 days, you have to do 1 million More than 4 million questions require a very powerful computer."
……
There are still 11 days left between the day when the newspaper was published and the weather forecast for spring rain in Huainan.
On the morning of March 3, it began to rain lightly under the gloomy sky in Shanghai.
"Mr. Zhu, Mr. Zhu, it rained on the 3rd in Shanghai. Will the rain drift northward, from southern Jiangsu to northern Jiangsu, and on the 10th to Huai'an?" Tang Hua called Zhu Kezhen early in the morning.
"That's not the case. There's no inevitable pattern between this and that. I'm still tracking the weather data for the last two days. If there's any news, I'll definitely go to the computer office to find you."
"Oh, so that's what it is."
At 10 o'clock in the morning, Tang Hua's family of three came to the bank of Huangpu River holding umbrellas.At the wharf a few hundred meters away, China's first [-]-ton ship, the "Jiangshe" freighter, has completed its outfitting and is going to sea for the first time today.
It took only three months for the "Jianshe" ship to go from the official design to the drawing. It was so fast because the Ship Design Institute had computers and ancestor-level CAD software. "Wheel of Victory", which is an enlarged version of "Wheel of Freedom".Afterwards, the Soviet Union slightly enlarged it and replaced it with Soviet power and electromechanical equipment. The "Jianjian" then referred to this revision of the Soviet Union.
The design period of "Jianshe" was three months, and the berth period was also three months. After launching, it took almost a year for outfitting.
Everything is difficult at the beginning. Of course, many problems will be encountered during the construction of the first destroyer and the first [-]-ton ship. After solving these problems, you will be more proficient in continuing to build in the future.
A grand celebration ceremony had been held when the "Jianshe" was launched, and there was also a celebration ceremony for today's maiden voyage, but Tang Hua thought it was better to look at it from a distance--you can see it more clearly if you look farther away.
“建设”号是1956型货轮的首船，全长169米、自重6000吨、载重13500吨，单台重油锅炉+单台6000千瓦蒸汽轮机，最高航速17节。
Makino Shigeru has been nagging since the "Jianjian" was launched, saying that the design is conservative.The self-weight is 5600~5700 tons, but three or four hundred tons of steel were added to increase the safety factor. During the outfitting and testing, it was found that the main structure of the ship is very solid, and its structural strength is actually excessive.
But this is not a big disadvantage for the "Jianshe", because after the delivery of the ship, it mostly runs coastal freight and short-distance ferries between Chinese ports and Rajin, North Korea. This kind of ferry can save a lot of cargo The fuel oil actually made up for the adverse effect of the "Jianshe" ship's self-weight slightly exceeding the standard.
"Dad, why is the bottom half of this big ship red?"
Tang Hancheng asked the question.
"Because the ship is now empty and has no cargo, a small strip of its red bottom is exposed on the water," Tang Hua said.
This is the maiden voyage, and the "Jianshe" basically travels empty, leaving the Yangtze River estuary and turning around in the sea before returning.If it doesn't fall apart at sea, when you come back and go to sea again, you can pack up the goods a little bit.If everything is still normal and there is no abnormal deformation when the hull is loaded with cargo, then it will transition to a fully loaded state and finally deliver the ship.
With the completion of the "Jianjian", another sister ship started construction in the 200-meter dock.
Now Chinese cargo ships and foreign cargo ships carrying goods to Chinese ports may be seized by the US Navy at any time in places where China's sea and air forces cannot protect them. Ships and cargo are auctioned for "debt repayment". It stands to reason that a dedicated offshore freighter is more suitable for the short-distance ferry between them.
The "Jianshe" or the 1956-type freighter is a ship with a long range and good seaworthiness, which is a bit wasteful.However, both the State Department and shipping companies said that considering future expectations, ocean-going cargo ships must be built, and the US maritime blockade cannot last forever.
……
Jiangnan Shipyard.
"The 1956-type freighter, the country plans to build 4 ships, this is the first batch."
Cheng Wang, director of the Shipbuilding Industry Bureau, talked about the next work arrangement at the Jiangnan Shipyard.
"Ships 2, 3, and 4 will continue to be built at a rate of six months from now on. After No. 4 ships leave the dock, the 200-meter dock will undergo technical transformation for a period of time, and then build military ships. Military ships The relevant information cannot be released to you yet, but in short, when we renovate the dock, we will have some information to disclose."
The director, secretary, and directors of each branch of Jiangnan Shipyard nodded to express their understanding.
"In 1958, your Jiangnan Factory, and Hudong Zhonghua, each had another task of dispatching 10 key personnel to Dalian, in order to transform the Dalian Shipyard to be capable of building Type 58 destroyers. The Dalian Shipyard was the Soviet Union Those who have been in operation have good hardware conditions and a lot of skilled workers, but what they lack is experience in building destroyers. After all, they have never built Type 56 destroyers, and the comrades you transfer must do their best to help them improve their level."
"So, will the comrades transferred to Dalian return to our factory after the work is completed?" a branch factory manager asked.
Cheng Wang: "It is only a secondment, not a permanent transfer. The Dalian factory must form a talent team by itself, which is the requirement of the Shipbuilding Industry Bureau and the Mechanical Engineering Department."
……
Shanghai Institute of Computer Science.
"Gaoyou Lake! Gaoyou Lake airflow appeared!"
On the afternoon of March 3, a new round of meteorological information was summarized and transmitted to Shanghai. After analysis and judgment, a small-scale and slow-winded air mass was formed over Gaoyou Lake and moved east-south.
But this offshoot air mass drove the National Weather Service team in Shanghai crazy.
Tu Changwang opened the Huanghuai map, and drew an arrow heavily on Gaoyou Lake with a pen.Although I use a lot of force to hold the pen straight, the arrow is still drawn a little wobbly.
"Mr. Zhu, your intuition is correct. The emergence of the Gaoyou Lake airflow has allowed us... to increase the accuracy of the 2.26 weather forecast from 60% to 80%."
Chapter 176, I don't have time to go to the meeting, come here
After the weather forecast was published in the newspapers, the National Meteorological Administration and the Institute of Computer Science had a very difficult ten days.
The calculated 10-15 day weather forecast for the Huanghuai area is not surprising in most areas. It is either sunny or cloudy. There is no rainfall, only the strength and direction of the wind. To be honest, the local people may not be very familiar with this. Interesting, but this early spring rain is an obvious and unavoidable celestial phenomenon.
Therefore, the weather forecast had to mention whether it would rain or not, but what I didn't expect was that the result calculated by the computer was very different from Ye Duzheng's experience. Under the debate, the decision was made by drawing cards to compare the size.
“涂局长，我们不是后来每48小时演算一次天气预报么，难道2月28日和3月2日算出来的结果还是处于混沌状态，3月3日的气象观测数据才给了决定性的证据？”
Tang Hua was very curious. In front of him, Tu Changwang, Ye Duzheng, and Zhu Kezhen looked like they hadn't slept well for several days, and they had heavy dark circles under their eyes.
Tu Changwang: "As a result of the second mid- and long-term weather forecast calculation for the Huanghuai River on February 2, the arrival of the above spring rain was delayed by 28 hours. We were all shocked when the result was calculated."
Tang Hua: "Can something like this happen again?"
Ye Duzheng: "This is meteorology..."
涂长旺：“3月2日我们进行了第三次运算，春雨到来的时间又往回提前了12个小时，也就是说，比2月26日运算结果还是推迟了24小时。”
