100 Hz～3.98 MHz下苹果虎皮病果实电特性研究（Dielectric Properties of Fuji Apple Superficial Scald in the 100Hz～3.98MHz Range）
苹果 虎皮病 电特性
2010/12/29
为了研究富士苹果虎皮病病果电特性的变化规律，探讨利用电特性参数的变化来反映苹果内部的物理化学变化，运用LCR型电子测量仪测定了100Hz～3.98MHz频率、（20±1）℃恒温条件下贮藏1、8、15、22和29d的虎皮病果实复阻抗、电抗、电导、电容和介质损耗系数等电学参数。结果显示：在同一贮藏时间下，随着频率的增加，果实的复阻抗、电抗值在减小，电导值则在增加；而电容和果实的介质损耗系数变化则没...
