通过观察瞬态激励交流切割石英换能器衰减的时间常数和频移，测量了3he - b在19 bar和36、60 MHz时的复声剪切阻抗，以及3he - a在23 bar和12、36、60 MHz时的复声剪切阻抗。
Measurements of the complex acoustic shear impedance of3He-B at 19 bar and 36 and 60 MHz, and of3He-A at 23 bar and 12, 36, and 60 MHz, have been made by observing the time constant and the frequency shift of the decay of a transiently excited AC-cut quartz transducer.
