摘　　要：本文综述了纳米粉体中团聚现象的早期研究与近期进展,简单地介绍了团聚的危害,详细分析了团聚体的分类及形成,并采用DLVO理论和双电层理论对团聚的机理进行了理论分析,列举了一些目前在纳米粉体制备过程中常用的控制方法,并对该研究方向的发展趋势及进一步控制纳米粒子团聚问题进行了探讨。The investigation and progress in the agglomerates of nano-particle powder are overviewed, the bane of the agglomeration is introduced in brief, and the classification and the formation of .the agglomeration are analyzed in detail in this article. The agglomeration mechanisms are analyzed by dint of the theory of DLVO and double electricity layer theory. Some conventional controlling methods used for the nano-particle powder preparation are mentioned. The further research on this field such as controlling agglomeration was referred.
