摘　　要：随机数在现代生活中,特别是在系统仿真中起着重要的作用。利用自然特性来得到随机数不太实用。因此,需要研究产生伪随机数的方法来满足不同的需求。首先研究生成均匀分布和白噪声伪随机序列的方法,然后给出了根据均匀分布随机序列产生任意概率分布的伪随机数序列的算法。并根据这些算法进行了建模仿真,且对仿真所得的伪随机数序列进行了统计分析,结果表明符合概率分布要求。Random number becomes much more important role in the daily life especially in the system simulation. But it is hard to get the random number from the natural phenomenon. According to the necessity to get pseudorandom number on the system simulation, Uniform distribution and white noise at first are studied . Then random number of the random probability distribution was got based on the uniform random number, the whole model was simulated and the simulation result is reasonable.
