我国为了要广泛了解真空技术在工业上 的应用,除对冶金、冷凉干燥、单晶制备、 真空泵等制造使用工厂外,也参观了真空蒸 馏,真空蒸镀等应用真空技术工业装置和使 用工厂。现在简略汇报如下: (一)真空蒸镀 日本制造真空蒸镀装置的工厂很多,凡 是制造真空设备工厂都生产蒸镀设备, In order to widely understand the industrial application of vacuum technology in our country, in addition to the use of metallurgy, cool and dry, single crystal preparation, vacuum pump and other manufacturing plants, we also visited the vacuum distillation, vacuum evaporation and other industrial applications of vacuum technology and the use of factories . Now briefly report as follows: (a) vacuum evaporation Japan made a lot of vacuum deposition plant, all manufacturing vacuum equipment factory production of vapor deposition equipment,
