摘　　要：本文以磷酸和磷酸二氢钾混合溶液为研究对象,测量了混合溶液在不同温度下的电导率;研究了电解质溶液的电导率随摩尔比的变化规律。结果表明:溶液的电导率随磷酸与磷酸二氢钾的摩尔比增加而增加,电导率与摩尔比之间的关系可用函数式δ=ln(x+P3)P1×ln(x+P3)+P2表示。The electric conductivity of the mixed liquor of phosphoric acid and potassium dihydrogen phosphate is studied under different temperatures, and the relation is discussed between the electric conductivity and the molar ratio of phosphoric acid to potassium dihydrogen phosphate. The results show that the electric conductivity increases along with the increase of the molar ratio of phosphoric acid to potassium dihydrogen phosphate. The abovementioned relation can be regressed as δ=ln(x+P_3)P_1×ln(x+P_3)+P_2
