准单色噪声是一类所谓真正有色的噪声.本文对准单色噪声驱动的耗散动力系统的信息熵演化进行研究，文中首先运用线性变换的方法给出了所研究系统的Fokker-Planck方程，然后结合Shannon信息熵定义推导了该系统随时间演化信息熵的精确表达式， 最后分析了系统耗散参数和准单色噪声对系统信息熵的显著影响.

The quasimonochromatic noise (QMN) is the “truly colored” noise, and in this paper the time derivative of entropy for a dynamical system driven by QMN is studied. The dimension of Fokker-Planck equation is reduced by way of linear transformation. The exact time dependence of the entropy is calculated based on the definition of Shannon’s information entropy. The relationship between the properties of QMN and dissipative parameters and their effect on the entropy is also discussed.[1] ［1］Gammaitoni L, Hanggi P, Jung P, Marchesoni F 1998 Rev. Mod.
