| 摘 要： | 本文给出了固体电导率与含水率之间回归一化线性数学模型,不同物质的线性模型仅斜率和截距不同,只要校正即可实现通用性,这与历史认识有差异,测量仪利用网络理论解决了高阻测量问题,利用线性叠加原理实现了温度补偿并提高了测量准确度,利用单片机对模型进行编程计算和校正,从而实现了智能化,采取隔离,滤波,ＷＴＤ等技术,提高了系统的可靠性。

| Abstract: | The normalized linear mathematic model of the conductivity to moisture content is given in this paper. The model of dissimilar mass is difference in slope and intercept,and the generalization can be realized by means of adjust. This idea is differ from traditional ideas. The instrument can measure high resistance by means of net work theory,realized temperature compensation and improved measurement accuracy by means of the principle of superposition, realized the intelligence by means of the single chip microcomputer, improved its reliability by means of the techniques of isolation,filter and WTD etc. |
