摘要：

The superfluidity for liquid He-4 confined in one-dimensional channels has been studied by means of torsional oscillator. In the present experiments, FSM16 with the channel of 4.7-nm in diameter was used, together with preplating monolayer N-2 film on the channel ( the effective diameter of 4.1 nm). As the channel is preplated, the superfluid transition temperature at 0.1 MPa shifts to a lower temperature from 1.81 K for 4.7-nm channel to 1.69 K for N-2 preplated one. The results show that the superfluidity is suppressed strongly with decreasing diameter.
