摘　　要：用60 Coγ源和搭建的电子学测量系统,测量了自制塑料闪烁探测器、3英寸的溴化镧探测器和电子学系统的时间分辨率,得到了圣戈班公司生产的3英寸溴化镧探测器的时间分辨率为(283.2±0.9)ps.Using a gamma radioactive source and a self-made electronic apparatus the time resolution of a 3-inch LaBr3 detector made by Saint Gobain Company （France） was measured. During the experiment, a plastic scintillation detector was used as a trigger, the time resolution of the plastic scintillation detectors and the electronics were measured respectively. According to the measured results, the time resolution of the LaBr3 detector was （283.2±0.9） ps.
