The invention provides a method of characterizing a micropore structure of a porous material on the basis of an imbibition gas-discharging process, and belongs to the technical field of characterization of materials. According to the method, imbibition gas-discharging apparatus disclosed by a patent CN101354333B can be utilized, a dynamics equation controlled by micropore orifice diffusion and surface adsorption is established for the imbibition gas-discharging process of the porous material, and imbibition gas-discharging curves are fitted to obtain equation parameters. The method is used todetermine relative sizes of micropore pore capacity and micropore pore diameters of the porous material, and provide guidance suggestions for preparation and application of the porous material. 本发明提供了种基于吸液驱气过程表征多孔材料微孔结构的方法，属于材料的表征技术领域。本发明利用专利CN101354333B公开的吸液驱气装置，针对多孔材料的吸液驱气过程，建立由微孔孔口扩散和表面吸附控制的动力学方程，对吸液驱气曲线进行拟合，得到方程参数，用于判断多孔材料微孔孔容和微孔孔径的相对大小，为多孔材料的制备和应用提供指导性意见。
