摘要
We treat not only macro ions as charged colloids but also small ions as counter ions dispersed in a solvent by Brownian-dynamics simulation. The size and charge of particles are changed, while the other parameters are fixed. We compare the simulation results with theoretical results by Tokuyama [Physea A 352 (2005) 252-264]. The results are in good agreements with the theory. Thus, it is shown that the short-time self-diffusion coefficient is decreased as the radius is increased.
