产生符合一定分布的随机数的方法是，先产生(0，1)均匀分布的随机数，然后通过一个适当的变换方法得到所要求分布的随机数。常用的均匀分布伪随机序列发生器有线性同余发生器和线性反馈移位寄存器两种。-That meet certain distribution of the random number is first generated (0,1) uniformly distributed random number, then an appropriate transformation method requested by the distribution of random numbers. Uniform distribution commonly used pseudo-random sequence generator has a linear congruential generator and two linear feedback shift register.
