本文给出了含水纸页的电导率测试实验的方法和结果，拟合出了电导率随水份变化的两段数学模型。尤为重要的是，归一化的电导率－水份关系数学模型对于不同种类、不同规格的纸页，在不同的温度、湿度等环境条件下，具有相同的电导率转折点。这一实验结果，对于诸如纸页、布匹、粮食、烟草、茶叶、棉花、土壤、煤炭、泥料和陶瓷等物品水份含量的电导法测定［１］有着积极的指导意义。
In this paper, the method and result of the conductivity test of aqueous paper sheets are given, and two mathematical models of conductivity change with moisture are fitted. More importantly, the normalized conductivity-moisture relational mathematical model has the same conductivity turning point for different types and different specifications of paper sheets under different environmental conditions such as temperature and humidity. This experimental result has a positive guiding significance for the determination of the moisture content of articles such as paper, cloth, food, tobacco, tea, cotton, soil, coal, mud and ceramics [1].
