【摘要】A stochastic dissipative dynamical system driven by non-Gaussian noise is investigated. A general ap-proximate Fokker-Planck equation of the system is derived through a path-integral approach. Based on the definition of Shannon's information entropy, the exact time dependence of entropy flux and entropy production of the system is calculated both in the absence and in the presence of non-equilibrium constraint. The present calculation can be used to interpret the interplay of the dissipative constant and non-Gaussian noise on the entropy flux and entropy production. 【总页数】6页(1561-1566) 【关键词】
