摘　　要：根据二相流理论讨论了磨料射流中磨料粒子的加速机理和运动规律，按喷咀收缩段为准二维流场，对磨料粒子运动方程进行了求解，并对磨料粒子速度和流场速度进行了比较，从而为磨料射流在实际应用中充分发挥效益提供了理论依据。Based on the two-phase flow theory, the acceleration mechanism and movementpattern of the particles have been discussed in this paper.On the principle of thequasi-tWo-dimenonal flow field in the shrink section of nozzle, the kinetic equation of particles bas bon solved, and a comparison between the velocity of the particles and that of the flow fieldhas also been made. This study has provided a theoretical basis for increasing the efficiency ofthe abrasive water jet in its practical use .
