The prime exponent p of even perfect numbers n = 2p-1 (2P - 1) was studied. And a conclusion of the hundred place number of even perfect numbers was given by using the C program of Chinese remainder theorem. And several corollaries on the mantissa of even perfect numbers were strengthened.%通过对偶完全数n =2p-1(2p-1)的素指数p的取值情况的讨论,并调用、执行中国剩余定理的C语言程序,给出了其有关百位数字的结论,强化了其一些性质.
