摘　　要：根据PIVS方法,搭建了适用于脉冲射流的粒度测量系统,提出了相应的粒度测量算法.利用计算机生成的标准粒子图像,进行了算法验证.分别利用该系统和激光粒度仪对小型喷壶的稳态流场进行了比较测量.结果表明:该系统能够得到瞬时粒度图像,可以实现非稳态流场的粒度测量.According to the PIVS method, a particle size measurement system for impulse anti-riots water cannon was set up, and the particle size measurement algorithm was proposed and verified by the standard particle image. The steady field of small scale sprinkling was measured both by this system and laser particle analyzer. The results showed that both the algorithm and the whole system were reliable, the instantaneous particle images could be gotten and the particle size could be measured by this system.
