文章介绍库尔特计数仪的电阻法计数原理。根据库尔特计数原理采用单片微型计算机技术,天津大学精密仪器厂研制出无水银控制系统,用于检测静脉滴注用注射液中不溶性微粒的微粒检测仪。与Colter—ZM型计数仪进行对比测试,主要性能指标已经达到库尔特九十年代初的水平。
The article introduces the Coulter counter counting principle of resistance. According to Coulter counting principle using single-chip microcomputer technology, Tianjin University Precision Instrument Factory developed mercury-free control system for the detection of intravenous infusion of insoluble particles in the particle detector. Compared with Colter-ZM type counter, the main performance index has reached the level of Kurt in the early nineties.
