Abstract：
The master equation is solved numerically for the mass drift and fluctuation of three reaction channels. The driving potential is calculated by means of the D. Myers' mass formula plus shell and paring corrections. The results indicated that the lack of mass drift in the range of zero to a considerable energy loss in heavy ion collisions could be explained by the transport theory. Due to small mass mobility coefficient the mass does not drift considerably during a short time interval. The effect of the shell structure in the driving potential is obvious for the mass relaxation in the low energy loss region.
