Exploring the Fokker-Planck or Langevin type transport equation from the un
derlying 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 nonlin
ear coupling between two subsystems is decisive for generating the transpor
t phenomenon.
