本文对微乳液的结构及特征作了概括的论述，着重对Ｗ／Ｏ微乳液制备超细颗粒的研究进行了评述，包括超细催化剂粒子、半导体粒子、磁性材料、陶瓷材料、感光材料等，分析了微乳液滴中超细颗粒的形成机理，讨论了用该法制备超细颗粒的影响因素，提出了这一研究领域的研究方向。

In this paper,the structure and the characteristics of microemusion have been explained generally. The application of W/O microemulsion to synthesizing ultrafine particles(UFP),including ultrafine catalysts, semiconductors, magnetic materials, ceramic powders, photographic films have been reviewed. The reaction mechanism of the formation of UFP in W/O microemulsion has been analysed,and the factors affect the formation of UFP have been discusses. The resrarch directions of this field have been presented.
