| 摘 要： | 针对Visual Basic 6．0内部随机数发生器，按无初始化、序列初始化和变量初始化等方法产生随机数序列，并对序列的均匀性和独立性进行实验．统计检验表明：该发生器性能优良，无初始化和序列初始化性能相近，其均匀性被拒绝的概率约l0％，独立性被拒绝的概率约30％．如果产生每个随机数时都以当前时钟对发生器进行初始化，所得序列的均匀性略有改进，但独立性不能通过检验．

| Abstract: | Non-randomized, series-randomized and every-single-variable randomized approaches are applied to verify the property of internal random function in Visual Basic 6.0, focusing on uniformity and independence. The statistical result indicates that the overall property of the internal function is pretty good. The properties of non-randomized and series-randomized series are much close, showing about 10% and 30% abandon rate of uniformity and independence respectively. If the function is randomized before every single variable is generated, uniformity is a bit better. However, the independence is deteriorating dramatically to be refused. |
