龙格-库塔法是工程中常用的求解微分方程的一种方法.而且具有四阶精度,因此应用很广泛.改程序给出了其源代码.-Runge- Kutta method is commonly used in engineering solving a differential equation methods. But with four bands precision, it is widely used. Changed its procedures is the source code.

PQ分解法潮流计算程序。既可以用于高压输电网的潮流解算，又可以用于低压配电网的潮流解算，还可以同时解算输电网 加配电网的混合潮流问题。-PQ decomposition process flow calculation. Both high-voltage transmission networks can be used to calculate the trend, but also can be used in the trend of low voltage distribution network solver, but also at the same time increase the supply grid solver distribution network issues mixed trend.

用C 语言编制了末端设置阀门的简单管道在阀门开启和关闭的情况下的管道一维特征线法计算程序，计算开始需输入管道的有关参数，如水库水位、流速、管道分段数、流速或者流量、管道糙率、波速等等。输出结果中包含管道末端阀门的压力、流速以及管道其他断面的流速和压力变化

这是关于文件操作的一个题，由题意可知，该题解决起来应该分为三个部分。第一部分即从in.dat中读入数据，第二部分即实现排序的算法，最后应该实现将排序的结果输出到out.dat中。-This is the document on the operation of a title, and that Italy, we can see that the solutions to the problem should be divided into three parts. The first part from in.dat read into the data, the second part of that is to achieve the ranking algorithm, the final order will be to achieve the results were exported to out.dat.
