摘要：
The mechanisms of the adsorption and condensation of benzene in a mesoporous silica gel at 310K have been investigated by SANS. Measurements have been made in situ during an adsorption/desorption isotherm cycle with a specially constructed cell using contrast matching conditions for the condensed fluid. The results are in accordance with a process of multilayer formation and subsequent capillary condensation, which develops around the zones of particle contact in the gel structure.
