【Abstract】 Based on a special property of prime numbers and its applications reported a prior, an improved method was addressed for generating longer period pseudo random numbers. Examples and congruential schemes of the new method were provided to illustrate its applications. Statistic results show that the new method has advantages of satisfactory statistic properties over the method previously reported and the multiplicative or mixed congruential methods, particularly in view of its long period of M(M-1) , where M is a super prime number.更多还原
