k_means
首先从n个数据对象任意选择 k 个对象作为初始聚类中心；而对于所剩下其它对象，则根据它们与这些聚类中心的相似度（距离），分别将它们分配给与其最相似的（聚类中心所代表的）聚类；然后再计算每个所获新聚类的聚类中心（该聚类中所有对象的均值）；不断重复这一过程直到标准测度函数开始收敛为止。一般都采用均方差作为标准测度函数. k个聚类具有以下特点：各聚类本身尽可能的紧凑，而各聚类之间尽可能的分开。(First, a data object from the n choose k objects as initial cluster centers and for the rest of the other objects, according to their similarity with the cluster center (distance), respectively, assign them to their most similar (represented by cluster center) clustering then calculated for each cluster center received a new clustering (all objects in the cluster mean) repeats this process until the convergence criteria begin until the measure function. Standard deviation is generally used as a standard measure function. K a cluster has the following characteristics: the cluster itself as a compact, but separated as much as possible between each cluster.)

说明：用的逐步定线方法，在解决这个问题中并不是一个很有效的方法，我想最好的方法为Dijkstra，但Dijkstra编起来比较简单（已有源程序，只须改变权矩阵），没有再进行练习。程序编制的比一些比赛论文中的要精细一些，但结果不是很好。(The progressive alignment method used in solving this problem is not a very effective way, I think the best way to Dijkstra, but it is relatively simple Dijkstra Code (has source code, just change the weight matrix), no further to practice. Programming than some games should be fine in a number of papers, but the results are not very good.)

电力系统的短路计算过程繁琐工作量大，采用计算机编程计算不但省去了繁琐的人工计算，而且精确度高。我选用matlab作为编程语言，因为Matlab对处理数组有着其它编程语言所无法比拟的优越性。此外matlab中的GUI界面直观简单，而且制作过程并不复杂。(power system short-circuit the cumbersome process of calculating workload, calculated using computer programs not only save a cumbersome manual calculation, and high precision. I use Matlab as a programming language, because Matlab have to deal with an array of other programming languages are incomparable superiority. In addition Matlab the GUI interface is very intuitive and simple, but the production process is not complicated.)
