线性回归法代替线性图解法

The Replacement of the Linear Diagram with the Linear Regression Method

本文提出用线性回归法代替线性图解法,并且通过具体实例说明这种代替的可能性和必要性。文中列举的实例分为四个部分:(1)线性回归法代替Gran图解法;(2)半波电位E_(1/2)^-及电极反应电子数n的测定;(3)恒电位电解中耗电量Q的测定及电极反应电子数n的测定;(4)测定金属在汞中的扩散系数的高鸿法等。

The replacement of the linear diagram with the linear regression method is presented in this paper. The possibility and necessity of the replacement have been illustrated by a lot of examples. The examples are divided into four parts, (1)The replacement of Gran diagramwith the linear regression method. (2)Determination of the half-wave potential, E1/2, and the number of electrons, n, in electrode reaction. ( 3 )Determination of the electric charge, Q, which has been consumed and the number of electrons in electrode reaction with controlled-potential method. ( 4 )Determination of metal diffusivity in mercury with Gao Hong method.
