支持公历、农历及公历转农历使用公式法（不是查表法）的日历控件，完全自主开发。- A fair experience, the lunar calendar and the male experience transfer the lunar calendar use formula law (is not Zha Biaofa) the calendar controls, completely independently develops.

可以识别图片中火焰区域，目前支持jpg和bmp格式图片。主要根据火焰的颜色来识别，同时结合火焰的边缘轮廓特征。对于视频中的火焰识别，已经在界面中添加了接口，后续还需要完善，识别的算法是一样的，需要解析视频后，将每一帧作为一个单独的图片来识别

kmeans聚类算法，在数据挖掘当中的应用，可用于时间序列数据的聚类，并能够显示聚类中心曲线，和聚类所用时间。代码简单容易实现。
