摘　　要：通过SEM等手段，建立了膨胀石墨颗粒结构的完整图象，并对其形成机理和影响因素进行了探讨。首次提出了分四级描述的结构模型，评价并总结了前人所提出的结构模型。该模型对膨胀石墨液相吸附机理的研究具有重要意义。： The structure of expanded graphite was studied by using SEM. A full structure model of expanded graphite was proposed, and formation mechanism and affective factors were discussed. A four－ grade pore structure model was brought forward for the first time, while all the previous structure models were evaluated. This model is of great use to the research on liquid－ phase adsorption mechanism of expanded graphite.
