孔口孔径测试介绍论文

Such a force can be used to probe the pore-mouth size, while the closure of the pore mouth can be probed by gas flux variation.Our preliminary tests on the new method with model samples are promising, and the results are well supported by those obtained by SEM, metallography, and the conventional bubble point method. Due to the convenience and effectiveness of this novel technique, we expect that the new method will be of wide use in the surface analysis of porous materials.
