摘　　要：针对耦合映像格子模型产生的时空混沌序列的特点,在符号函数二值化法的基础上,给出了一种新的二值化方法。随机性能和相关性检验的结果表明按这种方法得到的二值序列具有优良的伪随机性能及相关特性,说明提出的方法是有效的,而且简单实用。According to the characteristic of spatiotemporal chaotic sequences produced by coupled map lattices model, based on the binarization method using sign function, a new binarization method is proposed. The results of randomness and correlation tests show that the randomness of binary sequences given by the new method is good. Moreover these sequences have good correla- tion. These facts show that the new binarization method proposed in this paper is effective, simple and practive.
