布尔网络动态特性的研究已经成为国内外基因调控网络研究的重要课题.介绍了布尔网络动态行为的相关概念和最新进展,并采用计算机模拟布尔网络的动态演化过程,用消除趋势波动分析(DFA)方法分析了布尔网络的长程相关性动态特性.结果发现:绝大多数布尔网络呈现1/f波动;长程相关性值α与网络的连通度k有关,并随着灵敏度数值S的增加而减小.
It was introduced the dynamic behavior of the Boolean network ralated concepts and the latest progress, by using computer to simulate Boolean network dynamic evolution progress, and eliminate the detrended fluctuation analysis(DFA) method to analyze the dynamic characteristics of long-range correlation of Boolean network. Moreover, the DFA method was used to study the dynamic behavior of long-range correlation. The result showed that most of the networks emergence i/f fluctuation, and the fluctuation scope a of the network had to do with the connectivity k; When the noise increased, the long-range correlation value decreased.
