摘　　要：用发光二极管和光敏电阻及相应的电路组成测试系统,可将管道内的固相颗粒浓度转换成电信号,将该电信号和微机的A/D卡相连,可实现高速、连续、多点、在线测量管道内固相颗粒的浓度。The particle concentration of two-phase flow in vertical tubular leacher may be converted to electric signal through a metrical loop which consists of photie diode and photoresistor. This signal was linked with the analog-digital converter which was inserted in microcomputer, then the continuously, high speed, multiple points and on-line sampling of particle concentration was resolved.

关 键 词：停留时间分布 浸取器 固体颗粒
