如果一个序列,一方面它是可以预先确定的,并且是可以重复地生产和复制的;一方面它又具有某种随机序列的随机特性(即统计特性),我们便称这种序列为伪随机序列。(If a sequence is predefined on the one hand, it can be produced and replicated repeatedly; on the one hand, it has a random sequence of random properties (i.e. statistical properties), which we call a pseudorandom sequence.)
