Weather forecasting in this era relies on intuition.It's not the fortune-telling in the Book of Changes, but the intuition formed by meteorological experts who have been in the ocean of data for more than ten years.
The hydrodynamic calculation of the atmosphere can only be used as an auxiliary reference, because the calculation speed is too slow and the calculation accuracy is too low.
If Zhu Kezhen can sort out the atmospheric model and make it into an algorithm that can be calculated accurately, then computers can actually be applied on a large scale.
Of course, the current computer is still far behind the Galaxy I, but it should be able to make short-term weather forecasts for two or three days, and increase the reliability of calculations for medium- and long-term weather forecasts, making the calculation results more informative.
Then there are the Ministry of Geology, the Ministry of Water Resources, and the Aviation Industry Bureau and the Shipbuilding Industry Bureau of the Ministry of Heavy Industry—of course, the ship design institute has already taken the lead in using computer-aided design.
……
"I mainly came to see the prototype of the Chinese machine." Tang Hua said.
"There is only one computer in the whole computer, and all the other prototypes have been distributed." Lebedev and Tang Hua came to the office on the second floor. Here is a T53 computer that looks like a T54.
That's right, T53 and T54 are almost identical in appearance.
That's right, T54 was born 9 months ahead of schedule, because the development of this T54 was not technically difficult.
Or a transistor computer.The number of transistors is still just over [-].
The acceleration of computing speed depends on increasing the main frequency.
But there is one thing T54 is genuine and practical: it has a built-in 10M hard disk in the cabinet.
Last year, a 5M hard disk was released, and this year the hard disk capacity finally surpassed that profiteer IBM in history.And the size of the hard drive has shrunk slightly. The 5M hard disk is like half a gasoline can, and now the hard disk on the T54 is like half a lubricating oil can.
That is, the diameter is about a circle smaller, and the capacity is doubled at the same time.
"Its... system has been updated?" Tang Hua asked.
"Of course. The initial system installed for him already includes the Chinese system."
Tang Hua turned on the monitor switch, and then turned on the computer switch.
When the computer starts, the character strings appear line by line on the screen one after another.When the sixth line appears, the speed at which the characters appear becomes noticeably slower.This line is:
Chinese operating system-T54 version V1.0
Although I have seen the renderings of the Chinese dot matrix display at the Huawei Research Institute in Beijing a few months ago, this is the first time I have seen Chinese pop up on a computer that has been formed.
"When Wang Shoujue and the others saw Chinese characters displayed on the computer for the first time, how did they feel and what did they do?" Tang Hua asked.
Lebedev: "Almost knocked the roof off."
Tang Hua tapped on the keyboard and entered a command to list all the files on the hard disk.
……
Lebedev, the designer of the operating system: "Sorry, the file name does not support Chinese yet."
Tang Hua nodded helplessly, that's all.normal phenomenon.He opened one of the files that looked like a Chinese document.
"We are all from all corners of the country, and we have come together for a common revolutionary goal. We have to walk this road with the majority of the people in the country. Today we have led the base area with a population of 100 million, but it is not enough In order to achieve the liberation of the whole nation, our comrades must see the achievements, see the bright future, and strengthen our courage. The Chinese people are suffering, and we have the responsibility to rescue them. We must work hard. If we strive, there will be sacrifices. People die often. But we think of the interests of the people and the pain of the majority of the people. When we die for the people, we die for the people.”
"Tang, I am very dissatisfied with the Chinese system now," Lebedev protested, "It took me three years to learn Chinese, but this time, many Chinese characters in the Chinese system of the computer have changed. .I'm taking the time to reacquaint myself with the new typeface, which is a little difficult."
Tang Hua: "Well... this is the simplified Chinese characters that the country will implement soon, and the new Chinese Pinyin will be implemented at the same time. The original Chinese character system has more than 2 different glyphs. Our computer and our current storage system can accommodate It is too difficult to have so many character sets and fonts. In addition, the original Chinese character system has many characters with many strokes. When the current display system displays these Chinese characters, they will be blurry and difficult to recognize. Therefore, this version of the Chinese character system only includes commonly used characters. There are 6425 Chinese characters, including about 3000 simplified Chinese characters or radical simplified Chinese characters."
"According to the distribution of simplified and traditional Chinese characters, I am re-learning simplified Chinese characters. Fortunately, most of your simplified Chinese characters have rules to follow, except for a few. For example, this character has changed a lot."
Tang Hua looked at the simplified and traditional comparison table opened by Lebedev, Zhong (Traditional)----Zhong (Simplified)
"Old Lie, shouldn't the crowd be more intuitive? One, two, three, many people together, isn't it 'the crowd'?"
"Then what is the traditional Chinese?"
"The zhong in traditional Chinese characters is an error in the shape change of Chinese characters. We just corrected it now." Tang Hua said, "From 1600 BC to 1000 BC, China was born in oracle bone inscriptions, which contained the word 'zhong'. The shape of the characters is three human figures. But there is also a variant of the characters in the oracle bone inscriptions. Above the three people is a sun, that is, the crowd below the sun. This writing method was later inherited by the bronze inscriptions and seal script. By the Western Zhou Dynasty in 600 BC In the mid-period, there was a wrong inheritance of the font of "Shangri Xiazhong", and the horizontal sun at the top became the horizontal mesh. This small seal writing method came to around AD 25, and the one among the three people at the bottom changed from '人' has become 'T'. After Lishu, Zhongzi has gone further and further on the wrong path. At the beginning of this century, we discovered the lost Shang Dynasty relics and rediscovered oracle bone inscriptions, from which Guo Moruo deciphered Zhongzi , so decided to add it to the list of simplified Chinese characters.”
"Okay, okay, when it comes to history, all of you can talk about it from the prehistoric era... But at least I have firmly memorized the words." Lebedev admitted defeat, "Don, If you think it's too slow, you can overclock your computer by 1.5 times."
The monitor in front of Tang Hua displayed English and Russian documents, and the screen was full after a few swipes.The speed of displaying Chinese has slowed down significantly, one line, two lines, three lines, and the words are output at a leisurely pace.
When this monitor displays a document, there are only 24 Chinese characters in one line...
"Is overclocking really effective?" Tang Hua looked at Lao Lie.
"of course."
"Then I'll try."
Sure enough, after the frequency went up, the speed of writing words also accelerated.Probably... speeded up by 1.5 times.
……
"Report to the chief, downstairs are the staff who came to register the population."
At the gate of the yard, the guard asked what the two people who came to the door were doing, and came back to report.
Since it was indeed a staff member after checking his identity, Tang Hua still went down.Although the guards could answer and register on their behalf, Tang Hua just wanted to take a closer look this time.
"My family consists of 4 people. Tang Hua is me. I was born on July 1923, 7. My hometown is Luoding, Guangdong. I work as a cadre. Zhou Xuan is my wife..."
Tang Hua told the information about himself, Zhou Xuan, Tang Hancheng, and Aunt Ye. The staff took out a card from one satchel and put it in another satchel.
The first national census in 1953 was the first national census of new China.
This is also the reason why the building was empty when Tang Hua, where Shanghai Computer was located, arrived.
The standard day of the census was set at 1953:7 on July 1, 0, and more than 250 million people participated in the survey and registration work.In order to ensure the smooth progress of the national census registration work, census registration offices at all levels have been formed throughout the country, and a unified, simple and feasible national census registration method has been formulated.Most areas of the country strictly follow this method to conduct direct investigations.However, there are a few areas where direct surveys cannot be conducted, and surveys have been carried out by other means, mainly in remote areas where grassroots elections have not been held and where transportation is inconvenient.
The standard day of the census means "how many people are there in the country at 7:1 on July 0st." The census is not just on July 7st, but will last for a long time. The developed densely populated areas such as Beijing and Shanghai can be completed in about a month. It will take three months to complete the survey in remote areas.
The information asked by the census personnel when they came to the door was "how many people are there in your family at 7:1 on July 0st?" Children born after July 7st will not be counted even though they have already been born.As for the elderly who died after July 1, even though they were gone when the census personnel came to the door, they still had to be registered.
Because Taiwan Province had just been liberated, Wang Zhen specially ordered that when the census personnel came to the door, not two but four people, two of whom were carrying guns.
After the census is over, a spot check will be conducted to determine the error range of the census, and the spot check area will cover about one-tenth of the population.
In order to support this national census, the Bureau of Electronics and Information Industry produced a small batch of "early adopters" T54 computers and T54M medium-sized computers in advance for information processing and transmission of the census.
It just so happened that the Chinese character system was developed by Huawei's workaholics.It happened that the T54 computer had a 10M hard drive.
But 10M hard drives are impossible, and information storage ultimately relies on 25M tape drives.
In 1880, the United States conducted the first census in the modern sense, and it took seven years for the data returned by the investigators to be accumulated and counted.At this time, there are only 7 years left before the next census (the U.S. Congress mandates a census every 10 years).
By the beginning of the 20th century, IBM invented automatic machines, such as punches, to speed up the counting of census data.Later, after each census in the United States, it took about 2 to 3 years for the data to be accumulated and counted.
