一、引言在伟大领袖毛主席关于“努力办好广播,为全中国人民和全世界人民服务”的光辉指示指引下,经过无产阶级文化大革命,我国电视工业蓬勃发展。电视在巩固无产阶级专政的斗争中发挥着越来越重要的作用。为了适应我国人民在普及电视方面日益增长的需要,我们通过厂校协作,试制了一种采用低屏压的31厘米(以下简称12吋)显象管。这种显象管能直接安装在目前已经大量生产的9吋电视机上使用,所用的最高电压不变、偏转线圈也不变。因此对整机厂来说,12吋电视机需要改变的只是外壳(机箱),而内芯(线路部分)
I. INTRODUCTION Guided by Chairman Mao's great guidance on the brilliant instructions of “working hard to make the radio a success, serving the entire Chinese people and people all over the world,” the television industry in our country thrived after the Great Proletarian Cultural Revolution. Television plays an increasingly important role in the struggle to consolidate the dictatorship of the proletariat. In order to meet the growing needs of our people in popularizing television, we piloted a 31 cm (12 inch) kinescope using a low screen voltage through collaboration between the factories and schools. The kinescope can be mounted directly on the already mass-produced 9-inch TV, with the same maximum voltage and deflection yoke. Therefore, the whole plant, 12-inch TV need to change only the shell (chassis), and the inner core (line part)
