摘　　要：研究了从Gray-Scott系统中提取二值伪随机序列的方法,提出了一种改进的二值化方法,解决了利用GrayScott系统设计二值伪随机序列生成器的关键技术。通过大量的测试和分析说明得到的二值序列随机性能良好,改进的二值化方法有效。This paper studies the method of distilling binary pseudo-random sequence from the Gray-Scott system. As the key technology of designing binary pseudo-random sequence generator, an improved binarization method is proposed.The vast tests show that the randomness of binary sequences distilled from the system is good, this fact shows that the new binarization method is effective.
