中文摘要：
采用微波反射光电导衰减法设计了测试少子寿命的演示实验装置.实验装置主要由脉冲激光源、微波发射接收和数据采集处理系统等部分组成.该实验可以直观地演示非平衡载流子随时间的衰减过程,定量给出少子寿命、扩散系数和扩散长度.
英文摘要：
A minority carrier lifetime demonstration device was designed based on the microwave reflected photoconductance decay method.The demonstration device constituted of pulse laser source,microwave transmitter and acceptor,and data collecting and processing system.Using the demonstration device,the decay process of non-equilibrium carriers was visually demonstrated,and the minority carrier lifetime,diffusion coefficient and diffusion length were calculated.
