摘　　要：主要综述了3种利用超临界流体制备微粒的方法:快速膨胀法、超临界抗溶剂法和气体饱和溶液法,并着重介绍了这3种制备方法的原理、特点及其在应用方面的进展.The use of supercritical fluids as media for the formation of particles is a recent development. Three kinds of methods to prepare ultrafine particles by supercritical fluids are described, including rapid expansion from supercritical solution, supercritical anti-solvent precipitation and particles from gas-saturated solutions. Principles and characteristics of the three ways and progress in application of supercritical solution precipitation are introduced.
