中文摘要：
通过光电倍增管、电流测试仪、负高压电源、照度计等仪器的组合，设计了分压电路，搭建了模块化的光电倍增管特性测试的实验平台，实现了对光电倍增管暗电流、光电特性、伏安特性的测量．模块化的实验平台组合使得仪器装置具有良好的开放性，有利于学生直观认识掌握光电倍增管的工作原理以及性能参量的物理意义．
英文摘要：
By combining photomultiplier, amperemeter, negative high voltage power supply, illu- minometer and so on, an experimental platform was constructed for the purpose of studying the char- acteristics of photomultiplier （PMT）. Several major parameters and characteristics of photomultiplier had been measured and analyzed, including the characteristic of dark current, current-voltage charac- teristic under different light intensities and photoelectric characteristic. The experimental platform with modular design was open type, which could help student intuitively master the operating princi- ple and performance parameter of photomultiplier.
