(一)我们搞净化研究工作是从1961年开始的。当时,正是苏修背信弃义地撕毁合同,撤走专家,妄图破坏我国建设。为了国防尖端工程的急需,上级要我们承担这一光荣任务。净化是采用各种过滤措施,清除室内空气中的灰尘,为生产创造洁净环境的一门新技术。各种精密制造工业、国防尖端工业、高纯材料生产、医药卫生等部门都需要这种技术,以保证产品质量,增加产量。随着我国社会主义建设的迅速发展,净化技术越来越显得重要。如人造卫星和大型电子计算机需用的集成电路,要在一个米粒大小的硅片
(a) We started our purification research work from 1961. At that time, it was Su Shu that broke the contract in an unscrupulous manner and withdrew the experts in an attempt to undermine our country’s construction. For the urgent needs of the state-of-the-art defense project, superiors want us to take on this glorious task. Purification is the use of various filtering measures to remove dust from the indoor air and create a clean new environment for production. Various precision manufacturing industries, advanced industries for defense, production of high-purity materials, and medicine and health departments all need such technologies to ensure product quality and increase production. With the rapid development of socialist construction in our country, purification technology is increasingly important. Integrated circuits such as satellites and large computers need to be on a grain-sized silicon wafer.
