以英明领袖华主席为首的党中央一举粉碎了“王、张、江、姚”反党集团·全国人民响应华主席提出的“抓纲治国”的战略决策,高举毛主席的伟大旗帜,继承毛主席的遗志,为在本世纪内全面实现“四个现代化”,在科学技术上赶上和超过国际先进水平而努力奋斗。在这种大好形势下,上海锅炉厂,上海烟华玻璃厂,上海城建局测母总队,同济大学,上海市安装公司等单位和有关部队密切协作,胜利造成了二十米抛物面天线。遵照伟大领袖毛主席“我们必须打破常规,尽受采用先进技术”的教导,在设计天线时,采用了修正卡塞格伦天线;在结构理论分析时,采用了有限单元法;在精度检验时,采用了光学测耸技术。经过测试和使用,天线曲面精度和天线增益均特合设计要求。为便于交流,我们将《二十来天线结构理论分析和光学测全》资料编印出来,供有关单位参考。
The Central Party Committee led by Chairman Hua, the wise leader, crushed the anti-Party clique of “Wang, Zhang, Jiang and Yao” in one fell swoop. The entire Chinese people responded to Chairman Hua’s strategic decision of “grasping the guiding principle and governing the country”, held high the great banner of Chairman Mao and inherited Mao’s Chairman’s will, work hard for the full realization of the “four modernizations” in this century, and to catch up with and surpass the advanced international standards in science and technology. In this excellent situation, Shanghai Boiler Factory, Shanghai Yanhua Glass Factory, Shanghai Urban Construction Bureau measuring mother corps, Tongji University, Shanghai Installation Company and other units and the relevant forces in close collaboration, resulting in a 20-meter parabolic antenna. Following the teachings of Chairman Mao, the great leader, “We Must Break Rules and Adopt Advanced Technology,” we used a modified Cassegrain antenna in the design of the antenna. In the theoretical analysis of the structure, finite element method was used. , Using optical detection technology. After testing and use, antenna surface accuracy and antenna gain are special design requirements. In order to facilitate the exchange, we will “twenty to the theoretical analysis of the antenna structure and optical measurement of” data compiled for reference by the relevant units.
