摘要
本文对科学研究和工程应用问题中常见的多约束二阶非线性常微分方程的极值点进行了讨论 ,提出了一种数值解法 .以带有化学反应项的热传导方程为例 ,给出了相应的计算结果 .
The extreme value of second nonlinear ordinary differential equations with constraints which are seen much in scientific reseaches and on engineering projects, is discussed in this paper. A numerical method is introduced to solving this problem. As an example, numerical solutions at extreme value point on a heat conduction equation with a chemical reaction item, are given out.
