测量了吸附在多孔Vycor玻璃上的/sup 4/He膜的超流密度随温度的变化。薄膜的转变温度范围从0.1至1.5 K进行了研究。除了在5 × 10 ~（-3）/T/sub c/的量级上的小的舍入之外，这些膜的超流密度在类似于大块氦的转变附近遵循幂律。
The temperature variation of the superfluid density has been measured for /sup 4/He films adsorbed on porous Vycor glass. Films with transition temperatures ranging from 0.1 to 1.5 K were studied. Apart from a small rounding on the order of 5 x 10/sup -3/T/sub c/, the superfluid density of these films follows a power law near the transition similar to bulk helium.
