摘　　要：采用蒙特卡罗方法对GdZnTe探测器的探测性能进行了模拟计算,结合能量沉积和能量响应曲线特性分析的方法,得到了CdZnTe探测器尺寸变化与入射光子能量和探测效率之间的相互关系,为探测器的设计、实验及应用提供了一定的参考。The characteristic parameters of CdZnTe detector were simulated by Monte Carlo method with the analysis skills of energy deposition and spectrum calculated. The relationship between different crystal sizes of CdZnTe detector and detector efficiency with diverse incident energy of photon was obtained. This study work would provide reference for design, experiment and application of the detectors.
