| 摘 要： | 本文讨论了化工工程计算中常见的超方程的迭代计算方法。由于这种方程经常有多个解,但只有一个是有工程意义的。本文结合换热器计算讨论迭代法的应用,通过对超方程的数学分析,对迭代方法进行了改进,将迭代法和二分法相结合,获得了正确结果。同时讨论了牛顿迭代法在应用中应注意的问题。并根据Excel程序单元格内编辑公式的功能,讨论了Excel在迭代法中的利用。

| Abstract: | Solution of super-function in chemical engineering was discussed.The super-function often has more than one solution,but only one is reasonable in engineering.The discussion of iteration in the paper is based on calculation of heat exchanger design.The combination of iteration and dichotomy is proposed in the dicusion based on mathematical analysis of the super-function.The application of Excel program is also discussed since it has compiling function of equation. |
