Time dependence of information entropy of a dynamical system driven by quasimonochromatic noise
准单色噪声驱动的耗散动力系统的信息熵演化

The quasimonochromatic noise(QMN) is thetruly 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.
