when the mathematical model of practical problems is established.it often needs to establish the ordinary differential equations which physical quantities change at any time to solve the equations for the numerical solutions. Because of using various programming languages, it often encounters the following problems: how to solve the problem by various languages? What is the common tool software? How to transmit parameters between programming language and tool software?%在建立实际问题的数学模型时,常需要建立各物理量随某自变量变化的常微分方程组及求解,由于处理问题时使用的编程语言不同,经常会遇到如下问题:各种语言如何处理该问题？有哪些常用的处理工具？编程语言与工具软件的参数传递方法？
