一、前言一九五八年我国第一台钢中硅、锰、磷三元素自动分析仪[材研-1型]的问世,在化学分析界产生了强烈的反响。迄今湿法分析自动化已提到议事日程。十几年来各工矿企业结合自己的具体情况曾先后制成各种类型的硅、锰、磷三元素自动分析仪,并在生产上发挥了巨大的作用。 I. Introduction In 1958, the advent of the three-element automatic analyzer of silicon, manganese and phosphorus in China’s first steel [material research-1 type] produced a strong reaction in the field of chemical analysis. To date wet automation has been mentioned on the agenda. For more than a decade, various industrial and mining enterprises have made various types of automatic analyzers of three elements of silicon, manganese and phosphorus according to their own specific conditions and have played a huge role in production.
