英文摘要：

The advantages and applications of micro or nano - sized SiO2 were introduced. The mechanism and proeess of preparation of SiO2 in reverse mieroemulsion were described.Collecting from the literatures, the adjustment and control methods for particle size and morphology by changing the microemulsion parameters were summarized. The development foreground of preparation of nano - sized materials by reverse microemulsion were prospected.
