摘要
本文介绍利用介电特性进行水果品质检测的现状和电介质及介电特性的基本概念,并并提出基于介电特性的检测装置、测试原理,以及测试需要设置的主要参数。以苹果这一水果品种为例,对其进行了介电特性检测,测试结果表明,利用此方法进行品种识别,识别率在93%左右。
The actualities of nondestructive inspection of fruit quality by means of dielectric property and the essential idea and parameters of dielectric property were presented briefly.The equivalent model of medlum loss,the nondestructive inspection equipment based on dielectric property and the principle of experiment were given. The equipment was used to inspect apples in low frequency and the result showed that in the range of proper frequency,the parameters of apple dielectric property varied with frequency. Therefore the parameters could reflect the quality of apples on the whole.
