伽师瓜介电特性与其糖度的关系

Relationships between the Dielectric Property and the Brix of Jiashi Melon

为了解伽师瓜的糖度及成熟度对其介电特性的影响,研究了在10 k Hz射电频率下不同成熟度样品的损耗角正切值、品质因数等介电特性参数与糖度值的关系。考虑其个体重量不同等因素,引入单重正切值和单重品质因数作为评价伽师瓜介电特性的新指标,分析并指出了伽师瓜的糖度与重量及其单重正切值和单重品质因数的关系,并进一步探讨了射电频率对其单重正切值和单重品质因数的影响。

In order to investigate the influence of the Brix on the dielectric properties of the Jiashi melon,the loss tangent value,quality factor and other relative dielectric parameters of Jiashi melon with different maturity were studied at the radio frequency of 10 k Hz.Considering the difference of the individual weight of Jiashi melon,the unit weight tangent value and unit weight quality factor were introduced as new indicators for evaluating the dielectric properties of them.The relationships between the unit weight tangent value and unit weight quality factor and the brix of Jiashi melon were analyzed subsequently.Further,the influences of radio frequencies on the unit weight tangent value and unit weight quality factor were discussed.
