离子平衡近似计算的逐步逼近法

Proressive Approaching Method in the Approximate Calculaion of Ionic Equilibrium

本文对代数学中二分法、迭代法、牛顿法在离子平衡近似计算中的应用进行了阐述。说明了逐步逼近法的操作步骤与使用条件，并对离子平衡计算的精确计算法、逐步逼近法、近似计算法进行了比较与评述。

In this paper, the use of some digital methods such as dichotomy method, iter-ative method, newtonian method in ionic equilibrium approximate calculation is stated. Theoperations and uses of these methods are explained. Finaly the results from accurate calcula-tion progressive approaching method and approximate calculation are compared. It has beenfound that these progressive approaching methods can be used.
