利用智能ＬＣＲ测量仪和平板电极系统，用无损检测方法测定了桃子在储藏过程中电特性的变化。结果表明：在１２Ｈｚ～１００ｋＨｚ的频段内，桃子的最佳测试频段为１５ｋＨｚ以下，此时桃子随着储藏时间的增加，等效阻抗增大而相对介电常数和介质损耗因数减小；当桃子开始腐烂时，电特性数值出现了一个大的反复 Using intelligent LCR meter and plate electrode system, the electrical characteristics of peaches during storage were determined by nondestructive testing. The results showed that the optimum test frequency range of peach was below 15kHz in the frequency range of 12Hz ~ 100kHz. At this time, the equivalent impedances of peaches increased with the increase of storage time while the relative dielectric constant and dielectric dissipation factor decreased. At the beginning of decay, there was a big repetition of the electrical characteristics
