说明：  利用中心极限定理产生标准正态分布随机数，并进行检验；编制一个界面，产生（0，1）均匀分布随机数，并检验其主要统计量性质。(Central limit theorem using the standard normal distribution random number generation, and tested the preparation of an interface, resulting in (0,1) uniformly distributed random numbers, and verify the nature of the main statistics.)
