摘　　要：提出了夫琅和费衍射和激光多普勒效应相结合的三光束激光散射方法，详细研究并解决了该方法用于同时测量大于５μｍ粒子尺寸和速度时信号串扰问题，并用实验结果证实了理论分析。A three-beam laser scattering method combining Fraunhofer diffraction with laser Doppler effect is proposed. The problem of the signal cross-talk when measuring size and velvcity of particles bigger then 5μm simultaneously has also been analyzed and solved.Experimental results obtained have confirmed the analysis.
