"The tape drive has a large storage capacity and relatively low price, but we all know that it is a sequential memory. If the computer is required to randomly read a certain part of the data, the tape may have to idle for more than ten seconds to several minutes to find that part. The tape corresponding to the data."
"Hard disk—that is, magnetic disk memory. It is similar to random access memory. Its storage capacity is close to half of that of contemporary tape drives, but its price is dozens of times lower than that of magnetic core memory of the same capacity."
"Starting from the T54 computer, each type of computer will be equipped with disk storage as standard. The disk storage capacity installed on the T54 computer is 10M."
"Of course, due to the limited volume of the computer cabinet, and we are unwilling to increase the volume of the computer cabinet, the T54 does not have a built-in tape drive. If there are still users who need tapes for data backup, it is recommended to buy the latest external 25M Tape Drives."
……
It took Tang Hua several minutes to introduce the biggest selling point of the T54 - the hard drive.
Sure enough, the audience began to discuss with a bang.
Don't worry, the network card hasn't played yet...
In the center of the exhibition board, the screen of the slide projector was replaced with a simple cartoon. In a huge Soviet-style office building, the staff were laboriously moving documents, materials, books, and... tapes in various rooms upstairs and downstairs.
Then the screen continued to change, this time showing the structure of the computer local area network, each T54 computer stretched out the network cable and connected with the hub.
This is not just a blueprint, the two T54s on the venue are connected.
Tang Hua didn't operate it himself, and asked the participants to choose two representatives who could use the computer to use the T54 computer.
The T52, T53 and T54 computers all have a similar dos-like interface, so the operator has no difficulty using them.
Because the LAN connected by the network card is a short-distance network, the code rate of the direct connection of the communication cable is much higher than that of the telegraph line, and the maximum connection rate can reach 14Kb.
File transfer between computers, simple dialog windows...
Operations represent experimenting with new features of the T54 computer one by one.
In the end, the two operatives started the "Battle of Cubes" battle.
Tang Hua saw that the trial was almost done, so he changed to another slide projector film, which still had the structure of a computer local area network, but besides the T54 computer, there was also a large iron cabinet connected to the network.
"This is a data storage server that can be connected to the network and accessed by other computers in the LAN. Each T54 computer has a hard disk with a storage capacity of 10M, and this data storage server has eight 8M hard disks to form a storage array. "
"Of course, this is the data storage server with the largest configuration. According to the data requirements of various government departments, you can also choose the version with 6 hard drives or 4 hard drives."

"The development speed of computer and electronic technology is measured by index, but its price is not. Computer is the most cutting-edge product, but we have tried every means to improve its cost performance, because this is also the basis of scientific and technological progress. A kind of performance." Tang Hua said about the price, "Although the computing speed has increased by 40%, and it has network functions and large storage capacity, the price of each T54 computer is the same as that of the T53, and the price of each computer remains at 70 rubles."
“当一个用户购买的T54计算机数量大于或等于4台时，我们赠送集线器和网线系统。数据存储服务器，8硬盘版的售价是110万卢布，6硬盘版的售价是90万卢布，4硬盘版的售价是70万卢布。”
"In order to celebrate the great victory of China and the Soviet Union in North Korea, and to witness the friendly exchanges and cooperation between China and the Soviet Union," Tang Hua threw out the last easter egg, "Since it is difficult to upgrade the operating system of T50 and T51 computers, and its performance has already appeared to be backward. , so we also launched a trade-in activity for the T54 computer. You can use a T1 computer to discount 51 rubles, so that you only need to pay another 10 rubles when you buy a T1 computer. T54 computers can also be discounted to 60 rubles .”
……
"Tang Hua, what you said just now seems to have loopholes," Ambassador Zhang Wentian said quietly to Tang Hua at the end of the conference, "Did you forget to emphasize that only one old computer can be exchanged for a new one with money? Seven old T1s are here, and you want to take away a brand new T1, what should you do?"
老旧的T51其实不值10万卢布。确切地说……T50和T51计算机在国外售价是50万卢布，国内售价是50万人民币（45.5万卢布），而且其中超过一半的钱还是补贴-上缴利润的转账游戏。
In other words, even a brand new T51 computer three years ago was worth around 13 to 4 rubles.
Tang Hua: "They will never do it. If you bought a T51 unit to go back to use, it is absolutely impossible to throw away the computer. Not to brag, when the computer is generally used in a department for two or three years, suddenly it is impossible for them to work normally without the computer. Therefore, in the end, one old computer must be exchanged for one new one. Some departments even want to buy more computers.”
Ambassador Zhang: "Then these computers are purchased, are they going to be shipped back to China?"
Tang Hua: "Of course. Domestic Tsinghua University, Electronic Information University, and several electronic colleges and junior colleges all lack teaching aids. These computers can be brought back to China and refurbished, and they can be used by these schools for a few years to cultivate more advanced students. A lot of talent."

In the State Planning Commission of the Soviet Union, Sabrov tried to bring the topic back to the main topic and continued to discuss the implementation of China's first five-year plan.
"Last year we suggested that you set the annual industrial output growth rate target for the entire five-year plan at 15%, but when formulating the annual plan, the annual growth rate is 20%. The meaning is very clear. When everything is adjusted to the best At that time, the annual growth rate could reach 20%, and your industrial output value growth rate of 20.1% last year was no problem, which is very good.”
"In some years, the national economy and social structure need to enter a short period of adjustment. At that time, the growth rate in the five-year plan will be the year of the trough. There will be both the trough year and the peak year. After the implementation of the last five-year plan, the comprehensive growth If the rate is not lower than 15%, we will reach the target."
The chief accountant nodded.
Sabrov: "Because as the five-year plan is implemented year by year, there will inevitably be some places that have not been considered or not fully considered when the plan was formulated, and these defects may surface. It is impossible to formulate a plan. A five-year plan with absolutely no flaws. When flaws surface, we temporarily slow down the development of an industry to fix them. They must be fixed in time. If these flaws are ignored, it will spread and affect a The industry expands to affect the entire national economy."
Chief Accountant: "After a year of implementation, we feel that the support for agricultural production in the five-year plan is not enough, and the growth of agricultural output value may not catch up with the growth of industrial output value, and the gap between the two is still relatively large."
"The minimum line for the growth of agricultural output value is to ensure that during the implementation of the five-year plan, the increase in urban population will increase the demand for food and food."
"I'm afraid we can't just be satisfied with this minimum line. China... When we started building, China's per capita grain and meat per capita were at extremely low levels, which were one-half and one-tenth of the Soviet Union's respectively. one."
Sabrov: "Then increase the supply of chemical fertilizers, which is the fastest way to increase agricultural output value. In the medium and long term, in addition to the supply of chemical fertilizers, comprehensive water conservancy facilities should also be built, and then agricultural mechanization should be implemented in suitable areas Production. . . Damn, I'm still thinking about computers."
Chief Accountant: "Comrade Chairman,... I seem to have the impression that the State Planning Commission has a logistics director who attended the press conference, and he will tell you everything after he returns from the press conference. Or we can talk about it for five years later. If there is a plan, just ask about the situation of the press conference."
Chapter 35, the first optical fiber communication line
New York Times, February 1954, 2
"The second postwar recession is coming to an end, and the US economy is showing light"
"From June 1950 to April 6, dragged down by the war, government-led investment stimulus projects no longer increased, and the short-lived post-war prosperity disappeared without a trace. The post-war upsurge of the U.S. economy was interrupted by Influenced by the depression of the financial industry, the rate of industrial production in the United States fell by 1953% in 4, and in January 1952, it was expected that the industrial production in the United States would drop by 9.1 percentage points in 1953.”
"On April 1953, 4, Eisenhower, who had just come to power, decisively ended the Korean War. When the world media learned that the military demarcation line in the terms of the armistice agreement was actually closer to the South Korean side, some countries sneered, even though NATO's allies also felt melancholy about the final outcome of the Korean War. However, in the remaining eight months of 10, Eisenhower took the armistice as an opportunity to adopt a number of policies to stimulate the economy and restore growth, turning the military defeat into an economic victory. .”
“1953年4月，美国的失业率达6.2％，非金融企业的资产负债率达到35%。1953年12月，失业率已持续5个月下降，达到4.7%的水准，1954年1月更是降低到4.5%。”
"Due to the good operating conditions of the U.S. economy in the second half of the year, U.S. industrial production may reach a positive growth rate of about 1953% in 1, and the annual GDP growth rate will be 4-5%."
"The defeat of the Russian Empire in the Crimean War from 1853 to 1856 enabled Tsar Alexander II to initiate the 1861 reforms that brought Russia on par with the West in terms of capital and industry. A society driven by military defeat appears to be Development is not alone. The United States lost 3000 square miles on the Korean peninsula, but gained peace and development."
In 1953, China and the United States seemed to have good economic data, but the Soviet Union was not so good.
The industrial growth of the Soviet Union in 1953 was still acceptable. The steel output was 3800 million tons, an increase of 1952 million tons compared to 360.However, in 1953, the grain output of the Soviet Union was at a low point, only 8250 million tons, which was lower than the 1913 million tons of Tsarist Russia in 8600. GDP... The Soviet Union does not count GDP at the moment, and the growth rate is estimated to be less than 4% based on ppp parity.
And even if the grain output is taken into account, by 1955 the grain output of the Soviet Union had exceeded [-] million tons. In Russia, the annual grain output just jumped around with a large amplitude.

"President Lu, the strength of the Central Conservatory of Music is really impressive. The conductors of the Alexandrov Red Flag Song and Dance Troupe are full of praise for you."
The delegation of the Federation of Literature and Art had many exchange activities with the literary and art circles of the Soviet Union in Moscow. Tang Hua spent a week in Moscow and found time to listen to the concert of the Sino-Soviet Exchange Group.
Lv Ji, deputy dean of the Central Conservatory of Music, said with a smile: "It is Ma Sicong who has made great contributions to Yangyin in terms of classical music. As for me, the song I most want to sing in the Soviet Union is the first one just now, "School Song of the Anti-Japanese Military and Political University" But Minister Tang did not play the electric guitar and drums on stage this time, and Marco and I both feel regretful."
Tang Hua: "When I was in Moscow in 46 and 47, I was warned that anyone who played that thing in the big concert hall of the Red Flag Song and Dance Troupe would be thrown out of the concert hall."
Both Marco and Lu Ji laughed.
"This is the old calendar, who dares to throw out the person who won the Gold Star, haha," Marco said, "but "Birch Forest" is really amazing, I thought you were singing a Soviet song when I heard it, In the end, Zhou Xuan told me that it was written by you."
