说明：  这个程序可以算某个特征时间序列的影响因素的相关性。具体是通过比较两个时间序列的曲线相似度实现的。运行该函数前要先输入特征时间序列和影响序列。
(This program can be considered as a characteristic time series of the correlation between the factors. Specifically, by comparing the curve similarity of two time series. Before running the function, we should input the characteristic time series and the influence sequence.)
