叙述了用汞压法测定多孔材料的孔径分布、比表面和孔隙率等,讨论了用汞压法测定粉末粒度的原理和实验结果,研究了汞压回线及其在结构分析中的应用。 The pore size distribution, specific surface area and porosity of porous materials were described by using mercury pressure method. The principle and experimental results of measuring the particle size by mercury pressure were discussed. The application of mercury pressure return line and its structural analysis were also discussed.
