为了更广泛地宣传马克思主义、列宁主义、毛泽东思想,及时地传送毛主席的光辉形象,以及促进电视事业的普及,上级有关部门于一九七○年把研制油膜光阀外光源大屏幕投影电视机的任务交给了我们。研制这种电视机是一种难度高、综合性强的新技术,它对国防建设、工业和科学研究等方面,都具有重要的作用。这种电视机,国外从研制到能够提供使用花了约二十年时间,至今也只有为数不多的国家能够生产。他们把生产这种电视机,吹嘘得神乎其神,什么“特殊的阴极”、“特殊的油膜”、“特殊的××”等等,借此提高价格;又严密封锁资料,妄图垄断。
In order to promote Marxism, Leninism and Mao Zedong Thought in a broader manner, transmit the brilliant image of Chairman Mao in a timely manner, and promote the popularization of television programs, relevant departments at higher levels began to develop the large-screen projection television Machine tasks to us. The development of such a television set is a highly difficult and comprehensive new technology that plays an important role in national defense construction, industry and scientific research. This type of television set, which took about 20 years from the development to the provision of the use abroad, has so far been able to produce only a few countries. They have brazenly brazenized the production of such television sets, what “special cathodes”, “special oil films” and “special XX” to raise prices; and severely blocked information in an attempt to monopolize.
