七、常微分方程微分方程是描述化工问题的有效的数学表达方式。在这讲中,介绍常微分方程的数值解法。下一讲介绍偏微分方程的数值解法。我们知道,一阶常微分方程式 Seven, ordinary differential equations Differential equations is to describe the chemical problem of effective mathematical expression. In this talk, introduce the numerical solution of ordinary differential equations. The next one introduces the numerical solution of partial differential equations. We know that first-order ordinary differential equations
