中文摘要：

为探讨库尔勒香梨成熟期间电学特性的变化规律,以整个成熟期间的库尔勒香梨为研究对象,研究了测试频率、测试电压和采摘时间对整个成熟期的香梨电学参数的影响规律,并对电学参数的变化进行了分析。用Excel软件和SAS软件处理数据,结果表明：在测量参数范围内,测试频率对香梨的电感、电容、损耗角正切值等参数影响显著,采摘时间对电感和电容影响显著,且在测试频率≤10kHz时,随着香梨的采摘时间的延长,电感呈现逐渐增大的趋势,电容呈现逐渐减小的趋势。该研究结果可为基于电学特性的香梨成熟度检测提供参考依据。

英文摘要：

In order to investigate the variation of the electrical properties of the Korla Pear during maturation process , Korla Pear during the entire mature time were used .The affect that test frequency , test voltage and picking time on the entire mature pear electrical parameters was studied , the changes in the electrical parameters are analyzed at the same time .EXcelland SAS software were used to process the data , the results show that：in the measurement within the pa-rameters , the test parameters affect the frequency of pear inductance , capacitance , loss tangent value significantly , Pick-ing time significant influence of inductance and capacitance , test frequency less than or equal to 10 khz with the extension of pear picking time , the inductance gradually increasing trend , capacitance gradually decreasing trend .
