1·Some interesting phenomena are observed which related to acoustic streaming and acoustic radiation pressure.

这些现象与声流及声辐射压力有关。

2·On the contrary, when melt temperature is too low, the melt viscidity becomes intensive, so cavitation and acoustic streaming are in no effect.

如果施振温度过低，熔融合金粘度就会增大，致使声空化和声流效应发挥不了应有的作用。

3·Thus, the relationship between the rotating speed of the motor and some factors, such as the ultrasonic vibration of the stator, the fluid acoustic streaming field and the rotor radius, etc.

将声流场同电机转速联系起来，对电机转速同定子超声振动、液体声流场、转子半径等因素的关系进行了分析。
