The Mathematical Model for Capacity Grain Moisture Measuring Apparatus of Medium Changing Type

本文从介质变化型电容谷物水份测量仪的实际出发,在众多的因素中分析确定出模型的输入、输出变量。根据实验所得的数据,利用二元回归模型,求出模型参数,并讨论了模型的可靠性和精确度。最后由实验验证模型的正确性,从而为该类系统的设计提供一条可行的途径。

Considering the actual conditions of Capacity Grain MoistureMeasuring Apparatus of Medium Changing Type,the paper analyzes a numberof factors and then ascertains the input and output variables for themathematical model.According to the data obtained through experiments theparameters of the model are derived by using multiple regression with twovariables,and the model's reliability and accuracy are then discussed.Finally,the rightness of the model is proved by experiments presenting afeasible way to design this type of systems.
