摘　　要：以塔里木大学香梨园的香梨为材料,在不同夹持力和电极尺寸下,研究香梨电学特性并联等效电感、并联等效电容、品质因数、阻抗随夹持力和电极尺寸变化间的规律。结果发现,随着夹持力的增加,不同电极尺寸下测量获得的并联等效电感逐渐增大、增大幅度先大后小;并联等效电容、品质因数、阻抗均逐渐减小,减小幅度先大后小,各曲线变化情况大体一致。在不同电极尺寸下,随着夹持力的增大并联等效电感逐渐增大;并联等效电容、品质因数、阻抗逐渐减小,各曲线变化情况大体一致。综合分析:夹持力和电极尺寸的变化对香梨电学特性有一定的影响,而夹持力对电学特性的影响比较显著。研究结果可为库尔勒香梨电学特性的检测研究提供理论依据。This research used fragrant pear garden of tarim universitythe as materials.Under different clamping forces and electrode sizes,the change rule of law of parallel equivalent inductance,parallel equivalent capacitance,quality factor and impedance varying with electrode size and clamping force is studied.The results showed that with the increase of clamping force,the parallel equivalent inductance measured with different electrode sizes gradually increases,and the increase amplitude is large at first and then small;The parallel equivalent capacitance,quality factor and impedance all decrease gradually.The decrease range is large at first and then small,and the variation of each curve is generally consistent.Parallel equivalent inductance increases with the increase of clamping force at different electrode sizes;The parallel equivalent capacitance,quality factor and impedance gradually decrease,and the variation of each curve is generally consistent.Comprehensive analysis shows that the changes of electrode size and clamping force have a certain impact on electrical parameters of xiangli,and the clamping force has a significant impact on electrical parameters.The results can provide theoretical basis for the detection of electrical characteristics of korla pear.
