摘要：

We present grand canonical and canonical simulation results for the adsorption hysteresis in cylindrical and slitlike pores. Simulations for cylindrical symmetry were carried out for a continuous potential model, whereas the lattice gas was used to investigate the slitlike pores. In particular, we have studied the effects of pore ends on pore filling and pore emptying mechanism. We find that while the pore filling is unaffected, pore emptying is very sensitive to the presence of pore ends. Our findings confirm earlier lattice gas density functional theo results and indicate that fluctuations do not basically alter the mean field picture.
