摘　　要：利用粉粒光电分光器对等直径喷嘴中粉粒速度进行了实验研究．在实验的基础上，提出了用实测喷嘴内初始运动参数和出口压强确定喷嘴内粉粒初始速度的方法．结果表明，喷嘴内粉粒速度的计算结果同实测结果基本一致．A study on the particle velocity of gas-particle flow in the nozzle was made experimentally using photoelectric spectrometer of particles. A method to determine the initial particle velocity in constant-section nozzle is thus put forward in terms of measured initial parameters and the pressure at outlet. The results show that particle velocities calculated are in accordance with that measured.
