摘　　要：本文介绍用电子和正电子束流测试单通道电子倍增器的高压坪曲线、脉冲幅度分布和效率曲线;还用电子束流测试了阈电压和坪起始电压随电子能量的变化、增益随工作电压的变化、脉冲幅度与电子能量的关系、脉冲幅度和计数率随束流强度以及本底随工作电压的变化关系。The high-voltage plateau curve, pulse amplitude distribution and efficiency curve were measured with electron and positron beams. The variation of threshold voltage and plateau starting voltage with electron energy, the variation of gain with high-voltage, the relation between pulse amplitude and electron energy, the variation of pulse amplitude and counting rate with beam current, and the variation of background with high-voltage were also measured with electron beams.
