摘　　要：综述了对于超细粉体团聚有重要影响的范德华力、库仑力和空间阻力的研究进展。对引起范德华力变化的颗粒变形、气体吸附和表面粗糙等因素进行了详细的分析,这些因素都有可能导致理论分析结果的巨大差异,在实际应用中应仔细区分主次因素。The development of the research of the Van der Waals force, the Coulomb force and the space resistance, which have an important influence on the agglomeration of the ultra-fine powders, is reviewed. The effects of the powder deformation, gas adsorption and surface roughness on the Van der Waals force are analyzed in detail. All these factors may lead to a great difference in the theoretical analysis result and the primary and secondary factors should be carefully differentiated in the practical application.
