摘　　要：通过测量ＰＣ型ＨｇＣｄＴｅ探测器的动态响应，发现在工作温度（７７Ｋ）下，激光辐照后，探测器的电导率产生改变（记忆），电阻变化率提高，这种现象在工作温度下能长期保持．当升温（至室温）后，记忆功能消失．本文对这种现象进行了多方面的实验研究和机理的分析．By measuring the dynamic response in PC type HgCdTe detectors, it was found that at the operating temperature (77K), after laser irradiation, the conductivity of detectors changes (showing memory), and responsibility is raised up. This effect will remain unchanged for a long term at the operating temperature. When the temperature is raised to room temperature, the memory function disappears. Various measurement results were given on this effect and its mechanism was analyzed in this paper.
