摘要
证明了模n 剩余类环中元x 具有周期的充要条件是n/gcd( x ,n) 与gcd( x ,n) 互素,给出了 T 是Z/( n) 中某元的周期的充要条件.
It is proved that an element x in the residual ring Z/(n) has a period if and only if n/ gcd (x,n) and gcd(x,n) are relatively prime.Some necessary and sufficent conditions under which T is the period of some elements in Z/(n) are given.
