摘　　要：20世纪90年代以来撞击流领域研究重点转向以液体为连续相。液体连续相撞击流(US)具有有效促进微观混合和存在压力波动的特性,从而有利于超细粉体的制备。实验结果表明,浸没循环撞击流反应器(SCISR)是反应一沉淀法制取超细粉体的一种优越的反应技术装备。The emphasis of investigation on impinging streams has diverted to those with liquid as the continuous phase since 1990s. Liquid- continuous impinging streams （LIS） has two features, promoting micromixing effectively and therein existing pressure fluctuation, which favor preparation of ultrafine powders. Experiments show that SCISR is one of the outstanding equipments in preparation of ultrafine powders by reaction - precipitation.
