This story tells that before founding ceremony, Lin Zhiyuan, the first generation engineer in charge of the electric flag-raising device in New China, said during the equipment audit in founding ceremony that the electric flag-raising device could not be foolproof, so he was informed by his superiors that the previous time design of the device could not completely match the total length of the national anthem, and it must be revised and improved before six o'clock tomorrow morning to be foolproof.
With the help of people, Lin Zhiyuan finally completed the remanufacturing of the occlusion device under the great pressure of the first and superior requirements in China, and successfully refined the material of the occlusion device into steel. Regardless of his fear of heights, he climbed to the top of the flagpole as high as 2 1 m and personally installed and welded it, finally allowing the national flag to take off smoothly.
From Lin Zhiyuan, we learned the spirit of abandoning personal interests and caring about national honor; From the people, we have learned the spirit of helping others regardless of personal gains and losses.
The film also tells about the launch of the first atomic bomb in the history of China, the return of Hongkong to the motherland, the victory of War of Resistance against Japanese Aggression and many other important historical events. The great patriotic feelings shown in these events also deeply touched me.
As teenagers in the 2 1 century, we love our motherland, and we should do our best to defend our motherland like countless ancestors in history. Only in this way can we make our country richer and stronger!
More details are as follows:
On the eve of 1 949 65438+1October1founding ceremony in Tiananmen Square, a technician named Lin Zhiyuan served as the designer and installer of founding ceremony flagpole. However, in the flag-raising exercise, the frequency of playing the national anthem with the old tape recorder is different every time. Later, I found a student playing the national anthem with a trumpet in the Conservatory of Music, and the problem was definitely solved.
But all kinds of mistakes and problems are everywhere. When the national flag was raised, the power suddenly went out and the generator was found. Everything seems to be perfect, and my heart is put down. But when the national flag was about to rise to the top, the pulley at the top of the electric flagpole fell off the flagpole. The unexpected events make everyone feel at a loss, and it is getting closer and closer to founding ceremony.
Lin Zhiyuan calmed down and came up with a solution. In order to stabilize the pulley at the top of the flagpole, chemicals such as cobalt, chromium and tweezers need to be mixed and refined. After constant experiments and research, all the problems were finally solved in the last three hours of founding ceremony.
