摘要：

It is shown that the master equation for a superfluid Helmholtz resonator is ω2=un2ALV, where ω is the angular-resonant frequency, un is alternately the velocity of first, second, and fourth sound, A is the cross-sectional area of the neck of length L, and V is the volume of the resonator. The fourth-sound resonance occurs when the resonator is packed with a porous medium which locks the normal fluid component. Experimental results on such a resonator are in agreement with this result. © 1968 The American Physical Society.
