一个对Fluent中k-e湍流模型的修正udf程序，c语言(One pair ke turbulence model in Fluent udf amendment procedures)

C++编写的电力系统潮流计算程序，采用牛顿法，并考虑到节电优化编号，5,14,57,300节点验证正确(Power flow calculation program, C++ written using Newton' s method, taking into account the number to the power-saving optimization, 5,14,57,300 node authentication)

说明：  Optics聚类算法 OPTICS没有显示地产生一个数据集合簇，它为自动和交互地聚类分析计算一个簇次序。这个次序代表了数据基于密度地聚类结构。它包含地信息，等同于从一个宽广地参数设置范围所获得的基于密度的聚类(Optics do not show clustering algorithm OPTICS to produce a collection of data clusters, it is automatically and interactively computing cluster analysis a cluster order. This order represents the data to cluster based on the density structure. It contains in information from a broadly equivalent range of parameters obtained by density-based clustering)
