声辐射压被认为对于微重力下的固体 4He 实验非常有用。我们观察到声波对 4He 固液界面的操纵。我们在垂直于两个换能器之间的平坦界面的方向上施加声音脉冲。在低温下，界面沿声音方向移动。我们还检查了当声音平行于界面应用时界面如何移动。使用高速 CCD 相机记录声音脉冲期间和之后的界面动态。
Acoustic radiation pressure is thought to be very useful for solid 4He experiments under microgravity. We observed the manipulation of a 4He solid–liquid interface by an acoustic wave. We applied a sound pulse in a direction perpendicular to the flat interface between two transducers. At low temperatures the interface moved in the sound direction. We also checked how the interface moved when sound was applied parallel to the interface. The interface dynamics during and after the sound pulse were recorded with a high speed CCD camera.
