摘　　要：为弥补CZT探测器漏电流与结电容间接测量法的不足,采用直接测量法重新设计了测试方案。通过对CZT探测器的测试,给出了更精确的漏电流与结电容的数值,并将之与间接测量法的数据作了相应的对比,为CZT探测器的应用提供了更可靠的依据。In order to make up for the deficiency of the indirect testing methods of the leakage current and the junction capacitance of CdZnTe （CZT） detector, this article adopts direct testing methods of measurement to redesign testing solution. Through the test of CdZnTe detector, we get more accurate values of the leakage current and the junction capacitance and compare them with the values of indirect methods, thus providing more reliable reference for its application in the field of radiation detection.
