摘要：

It is shown experimentally that the superfluid fraction ρsρ is continuous and finite at the point at which superflow vanishes in unsaturated helium films. It follows that there is a region of superfluidity without superflow. In addition it is shown that the behavior of the partial molar entropy may account for the disappearance of superflow without requiring that ρsρ vanish. © 1969 The American Physical Society.
