摘　　要：The cryo-fracture electron microscope was used to study the micro-structure of pesticide microemuisions. The hydromechanical radius (Rh) and the distribution (fRh) of pesticide microemulsions were determined by photo-correlation spectroscopy. This study showed that the Rh was significantly greater when the ratio of surfactants to water (w/w) decreased to 20/31 from 27/26, and a bicontinuous structure was formed when the ratio dropped to 15/36. These results explained the relationship between pesticide properties and the microscopic structure, and provided a good method for studying the microscopic structure of pesticide formulations. 关键词：PESTICIDE microemuision, THERMODYNAMIC stability, MICROSCOPIC mechanism, Cryo-fracture,Photo-correlation SPECTROSCOPY
