摘要：

We have carried out QCM measurements for He-4 films adsorbed on porous gold in the crossover region between the superfluidity and the slippage. In relative low areal densities, the resonance frequency increases gradually below T-S due to the slippage of solid film, while the superfluid onset is observed in high areal densities. In the crossover region, we observed a peculiar behavior: The increase in the resonance frequency below T-S is suddenly suppressed at a certain temperature T-D. From these observations, it is concluded that the superfluidity and the slippage of He-4 competes with each other.
