对豆瓣书籍中的证券相关经典书籍进行收录并按照如下算法计算的结果从高到低排名
weighted rating (WR) = (v ÷ (v+m)) × R + (m ÷ (v+m)) × C
R = average for the movie (mean) = (Rating) - 单本书籍的得分
v = number of votes for the movie = (votes) -单本书籍的有效评分人数
m = minimum votes required to be listed in the Top 250 (currently 25000) -入选top250榜单所需最低的有效评分人数
C = the mean vote across the whole report (currently 7.0) -所有书籍的平均分
计算时设置m=500,C=7.5
