K-means算法是基于划分的思想，因此算法易于理解且实现方法简单易行，但需要人工选择初始的聚类数目即算法是带参数的。类的数目确定往往非常复杂和具有不确定性，因此需要专业的知识和行业经验才能较好的确定。而且因为初始聚类中心的选择是随机的，因此会造成部分初始聚类中心相似或者处于数据边缘，造成算法的迭代次数明显增加，甚至会因为个别数据而造成聚类失败的现象。(K-means algorithm is based on the idea of partitioning, so the algorithm is easy to understand and the implementation method is simple and feasible, but it requires manual selection of the initial number of clusters, that is, the algorithm is with parameters. The number of classes is often very complex and uncertain, so professional knowledge and industry experience are needed to better determine. Moreover, because the selection of initial clustering centers is random, some initial clustering centers will be similar or at the edge of data, resulting in a significant increase in the number of iterations of the algorithm, and even the phenomenon of clustering failure due to individual data.)

关于python学习的一本书，可以参考，是英文版的。(A book on python and computer)

Delphi编写实现的服务器监控程序，监控服务器的网络状态，用有icmp.dll，打开程序后读入任务列表，双击所选任务即可开始，定时使用ping命令对每个主机进行网络连接状态检查，并将结果写入监控日志文件。

这个是一个完整的3Ddemo，通过mascot v3引擎实现。-this is a complete 3Ddemo, mascot v3 engine to achieve.

用godunov方法求解黎曼精确解，帮助理解黎曼问题，了解计算流体力学(Solving Riemann exact solution by Godunov method.Help to understand Riemann problem and computational fluid dynamics.)

c++一群性质相近同的「东西」，如果译名一贯，阅读的感觉就很好。 一贯性的术语，扩充性高，延伸性高，系统化高。-c with a group of similar nature "things", if consistent translation, reading the feeling is very good. The consistency of terminology, scalable, extensible, highly systematized.
