Exploring the Fokker-Planck or Langevin type transport equation from the underlying dynamics, we study by exploiting the numerical simulations whether or not one may expect dissipative motions in a Hamilton system with finite degrees of freedom without introducing any statistical concept. It will be shown that the macro-level transport phenomenon in a finite system can be dynamically established from the underlying Hamilton system, and the nonlinear coupling between two subsystems is decisive for generating the transport phenomenon.
