摘要：

We report on the hysteresis and avalanche behavior of He-4 capillary condensing into the nearly cylindrical pores of the porous membrane Nuclepore. Following capillary condensation, withdrawal of the He-4 results in distinct jumps or avalanches where 10(7) pores can be involved in a single avalanche. By using Nuclepore with 2000 Angstrom and 300 Angstrom pore diameters, we find that the avalanche distribution depends on details of the pore structure.
