摘要：

We have designed equipment that measures, by means of capillary flow porometry, the pore structure of sheet materials. The equipment measures the influence of superimposed compressive stress on pore structure as well. The bubble point pressure, mean flow pressure, and flow distribution of a battery separator have been measured, and the influence of compressive stresses on these parameters have been observed. Our results demonstrate that the pore structure fur in-plane flow is considerably different from that for flow in the perpendicular direction, and the effect of superimposed compressive stress is appreciable.
