Study on LRCBridge for Examination of Tea Quality

摘要: 介绍了采用仪器进行客观、快速、正确测定茶叶品质的方法。包括测试仪器选择、传感器设计、品质数学模型的建立和测定方法。试验结果表明，采用ＬＲＣ数字电桥，对以电容为主要依据的多项电特性参数值的测定，能检测茶叶的综合品质，正确判别率达９４％以上。

Abstract: It is necessary that tea quality can be measured with an instrument. This paper introduced a series of work to solve this problem， including the selection of instruments， the design of a sensor, the establishment of a mathematical model and the measuring method. The experimental result showed that the electric capacity of tea measured with a numerical LRCbridge can be used to evaluate the tea quality, the rate of correct examination is above 94 %.
