摘　　要：本文就测量试品介质损耗角正切(tgδ)时,测量结果受各种因素的影响,造成实测值与实际值产生误差,甚至出现负值的原因进行理论分析,从而为现场测量tgδ的结果分析和解决方法提供参考。In this paper,we analyzed the reasons for the deviation between measured value and actual value and even why negative value appeared when we measured tgδ because of various of factors that can be responsible for the measurement. In this way,we can offer reference for analysis of field data and solutions.

关 键 词：TGΔ 负值 分析
