摘要:

The problem of effusion of a dilute gas through a hole by means of van Kampen’s systematic Ω expansion has been studied. In this way, the macroscopic equation as well as the Fokker–Planck equation for the fluctuations around the macroscopic behavior have been obtained and some dubious points in a recent analysis of the problem clarified.
