由于半导体工艺的发展,提出了加工制造大型方形管道的迫切要求,但过去一直没有真正解决这个问题。在学习无产阶级专政理论的热潮中,我们乘推优会战的东风,用“两论”(矛盾论、实践论)为武器,运用优选法,经过多次试验,终于成功地制成了任意尺寸的方形石英管道,从而满足了工艺的要求。过去加工方形石英管道的办法是先将直径为100毫米的园形石英管切成环,再加热坦成平板,把石英板切磨好后,再烧焊成型。这种加工方法存在不少缺点:
Due to the development of semiconductor technology, the urgent requirement of processing and manufacturing large square pipes has been put forward. However, this problem has not been solved in the past. In the upsurge of learning the theory of the dictatorship of the proletariat, we took advantage of the Dongfeng campaign of “pushing forward the superiority of the battle” and used the “two arguments” (contradiction theory and practice theory) as the weapon to optimize the dictatorship of the proletariat. After many tests, we finally succeeded in making any size Square quartz pipe to meet the process requirements. In the past, the method of processing square quartz pipes was to cut a circular quartz tube with a diameter of 100 mm into a ring, then heat and flatten the flat quartz plate, cut and grind the quartz plate, and then weld and shape. This processing method has many disadvantages:
