Abstract
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.
