高斯函数的一个重要性质

An important property for the Gauss function

从素数与合数两方面入手,研究阶乘、整除及高斯函数三者间的关系,归纳出高斯函数的一个重要性质:若n是一个正整数,则[(n-1)!/n(n+1)]是偶数.

In this paper, starting from prime numbers and composite numbers, we study the relationship among the factorial, divisibility, and Gauss function, and obtain an important property for the Gauss function, i.e,[（n-1）!/n（n＋1）]is even for an arbitrary integer n.
