Abstract：
The first and second moments of charge (mass) in dissipative heavy-ion collisions of mass-asymmetric systems have been calculated by means of the dissipative dynamic equation coupled to the master equation. The calculated results illustrate very well the experimental drift of the first moment of charge, which cannot be explained by the normal diffusion model. The second calculated moment of charge also agrees with the experimental data very well.
