摘要:

The velocity and attenuation of sound at 1 mc/sec. were measured in helium at pressures as low as 0.1 mm Hg (sound frequency about twice mean collision rate). The observed dispersions are very large and agree well with those predicted by existing theories except at very low pressures where uncertainties are introduced by lack of gas purity.
