| 摘 要： | 利用相耦合模型，推导出大雷诺数下悬浮固粒存在于射流区的运动射流的稳定性方程，通过数值计算得到了不同运动速度和不同固粒属性的流场稳定性特征曲线，进而得到了关于悬浮固粒的属性及流场运动速度对流场稳定性影响的结论．这些结论对于运动两相射流的发展认识和工程实际中实施对运动两相射流场的人工控制有重要意义．

| Abstract: | The stability equation of suspended solid particles lying in the inner of moving jet under large Reynolds number was theoretically derived by means of the phase\|coupled model. Then the stability curves for different velocities of jetting device and particle properties were got by numerical computation. Further, several conclusions on the effect of particle properties and natures of flow\|field on the stability of moving jet on the basis of analyses of the obtained stability curves were given. These conclusions are beneficial to learning the development of moving jet containing suspended solid particles and executing artificial controls over two\|phase jet flow\|field. |
