研究了不同枸杞品种果实介电参数与测定频率、贮藏时间的相关性，并就此相关性进行了探讨，为下一步研究枸杞果实介电参数与内部品质间的相关性打下良好理论基础。研究结果表明：枸杞果实介电参数值会随测试频率的增加而呈规律性变化，阻抗Z、电感 L、电阻R 值随测试频率的增加而减小；在全频率段，各处理组介电参数值无明显差异性，其显著差异性主要表现在低频阶段。3．98 MHz 频率下，阻抗 Z、电阻 R、介质损耗因子ε″与贮藏时间线性正相关，电容C、介电常数ε′与贮藏时间线性负相关。各枸杞品种的电容 C、介电常数ε′、介质损耗因子ε″随贮藏时间的变化值均存在显著差异性。

The correlation analyse were used to research the relation between electrical properties and test frequency of Lycium chinense varieties .Then , it were also be used to research the relation between electrical properties and storage time.it found the well-kept foundation for research the relation between electrical properties and internal quality of ly -cium chinense.The result showed:The electrical properties changed regularly with test frequency.The complex impendence,inductance, resistance decreased with the increase of test frequency .It showed some difference only in the stage of low frequency among Lycium chinense varieties .The complex impendence , resistance , loss factor were positively correlated with storage time .Capacity , dielectric constant wew negative correlated with storage time .At the same time , capacity , dielectric constant , loss factor showed a big difference among varieties when it been storaged .
