压汞过程中汞滞后体积早已为人们发现,当压力还原时,孔内依然保留部分汞,汞滞后体积依赖于多孔材料(例如大孔离子交换树脂大孔吸附树脂或分子筛等)的孔结构。
Mercury hysteresis volume has long been found in the process of mercury intrusion, when the pressure is reduced, the hole still retains part of the mercury, mercury hysteresis volume depends on porous materials (such as macroporous resin macroporous resin or molecular sieve pore structure).
