摘　　要：针对化工计算中经常出现无法对方程组直接联立求解的情况 ,探讨采用两种试算法。试算过程中初值的设定及修正是该法的关键。文章分别以流体流动和传热过程为例 ,讨论了计算过程较为简单 ,仅适用于关联各变量的方程可转化为单一对应关系的简单迭代法 ,以及可普遍适用于各种试算过程 。Tria and error solution is usually used in the calculation of chemical engineering when the solution can not be obtained through solving equations directly,the key of the method of trial and error solution is the setting and revision of the initial value.This paper,citing examples of fluid flow process and heat conduct process respectively,discusses simple interactive method with narrow scope of application and drawing method with common application.

关 键 词：试算法 初值 简单迭代法 作图法 化工计算
