摘　　要：应用变量代换、回归分析法并借助计算机技术 ,对在不同温度下测得的一系列标准溶液结果进行回归拟合 ,建立了关于电动势 E、温度 T和浓度 CF 的一个数学模型。该模型较好地解决了温度对氟测定的影响 。A methematical model pertaining to electromotive force E , temperature T and concentration C F is established by regressive simulation of results obtained from a series of standard solutions under different temperatures and calculations of variable substitution and regression analysis are performed by a computer. The problem of the effect of temperature in the determination of fluorine can be solved by this method.
