本文报道了外加直流磁场对超声波在磁流体中传播速度影响的实验结果。测量已进行了各种场强和两个频率的超声波，2和3MHz，并为平行和垂直方向的磁场相对于波的传播矢量。此外，从实验和理论上分析了直流磁场中声速的各向异性。
Experimental results for the influence of an external DC magnetic field on the propagation velocity of ultrasonic waves in a magnetic fluid are reported. Measurements have been carried out for various field strengths and two frequencies of ultrasonic waves, 2 and 3MHz, and for parallel and perpendicular orientation of the magnetic field relative to the propagation vector of the waves. Moreover, the anisotropy of the sound velocity in the DC magnetic field are analyzed both experimentally and theoretically.
