随机系统的噪声

The Noises in The Stochastic System

对随机系统的研究越来越受到科学家们的重视。研究随机系统就离不开噪声,本文对随机系统的噪声从其分类、起源、测量、关联和传递等方面进行了阐述。并通过一个具体的复杂的随机系统对噪声进行了量化。当不考虑噪声间的关联时,给出了噪声的加法规则。当考虑到噪声的关联时,通过分析级联的调控网络,分析了噪声的关联和传递的机理。最后进一步阐明了随机系统调控网络中噪声的传递和关联的重要作用。

The research on the stochastic system is expected to be of great interest from researchers of different scientific fields.And the noise is very important in the research of the stochastic system.Furthermore,the classification,origination,measurement,correlation and transmission of the noises are clarified in this paper.In addition,the noise of a complex stochastic system is quantified.When the correlation between noises is not considered,the noise addition rule is given.However,when the correlation between noises is taken into account,the mechanism of correlation and transmission of the noises is analysed through a cascade regulated network.Finally,the importance of the correlation and transmission of the noises in a regulated network of the stochastic system is clarified further.
