摘　　要：蒙特卡罗方法是数值模拟中一个很常用的计算方法,应用范围很广泛,并常常作为数值仿真算法的基准．概率模型和伪随机数发生器是蒙特卡罗法中两个很重要的组成部分,它们决定了蒙特卡罗法的正确性和计算精度．本文提出了一种比较充分的检验方法—三维介质辐射对称性检验法,它可在不同条件下对各种伪随机数程序进行无限制的检验,在更精细的层次上区分伪随机数发生器的优劣,同时还可检验概率模型的正确性。Monte Carlo method is popular in many areas of computational mathematics and is usually treated as benchmark method for numerical simulation algorithms. Probability models and pseudorandom number generators are two important component part of Monte Carlo method, and they influence the accuracy and correctness of the calculation. As a new test method, the symmetrical test method of radiation in three-dimensional media is presented in this paper. Using this method, an unlimited number of tests can be done on the pseudorandom number generator in various conditions. It tests not only the characteristics of pseudorandom numbers, but also the correctness of the probability models.
