一、 SX 0 41光栅数显仪开发的背景 用数控及数显技术对现有机床产品进行更新换代,对旧设备进行技术改造已成为我国“七五”期间的一项重要技术政策。我所在总结多年光栅技术经验的基础上,通过与国外技术合作和对国内外样机的对比、分析与消化,跟专门开发大规模集成电路的香港? First, the SX 0 41 grating digital display instrument development background CNC and digital display technology to replace the existing machine tool products, technological transformation of the old equipment has become China’s “Seventh Five-Year” period is an important technical policy. Based on the experience of many years of grating technology, I have analyzed and digested the cooperation with foreign technical cooperation and comparison of domestic and foreign prototypes, and Hong Kong that specializes in developing large scale integrated circuits.
