摘　　要：利用整数的偶数因子的个数，推导出了判断任意一个组合数的奇偶性的方法，和计算组合数集合｛Ｃｋｎ｜ｋ＝０，１，２，…。In this article with the number of even factors of an integer a method for deciding odevity of an arbitrary combinatorial number is derived and a calculating formula for calculating number of odd interger in combinatorial numbers {C k n|k=0,1,2,…,n } is also obtained.

关 键 词：组合数 奇数 偶数 奇偶性
