| 摘 要： | 从推广匹配问题解的角度再次引出了一种新的离散型分布──匹配分布，得到与候劲在１９９０年的结果相同：对于正整数ｎ，数列是一个离散型概率分布；并利用二阶Ｓｔｉｒｌｉｎｇ数给出了匹配分布的高阶原点矩以及一些数字特征，从而完善了侯劲在１９９０年的讨论．

| Abstract: | A new discrete distribution-marching distributinn was derived from extending the solution of matching problem, the same result has been obtained as Hou Jin's in 1990: For a positive integer, the sequence of number is a discrete probability distribution. The higher-order origin moments and some numerical characteristics of matching distribution were given by using 2- order Stirling number, thus the 1990-discussions of Hou Jin was imporved. |
