摘要
鉴于多数人在化学计算中,对高次方程求解感到困难,本文对多元酸电离和络合平衡中常遇到的高次方程作了例解:先用实验法求出当f(x)变号对x值所在的区间,再用累试法求出根的精确近似值。弦位法和切线法是累试法的捷径。
This paper deals with the equation of higher degree encountered frequently in ionization of polybasic acid and complexing balance for many people feel it difficult to solve it. The auther gets the placed interval of the value of f(x) signs revesal through experiment method and obtains the approximation of the refined calculation of the root through accumulated experimental method, the subtend method and the tangent method are the short cut of the accumulated experimental method.
