摘　　要：本文在已知输出的条件下 ,对带 1比特记忆组合生成器进行了条件相关性分析 ,证明了条件相关系数平方和不小于无条件相关系数平方和 。Conditioned on the known output digits, the correlation properties of the output sequence and input sequences of combiners with 1 bit memory are analyzed. It shows that the sum of the squares of the conditional correlation coefficients is not smaller than that of the correlation coefficients. And the necessary and sufficient condition for them to be equal is determined.
