摘要：

The effects of the He-4 interfacial layer on the average superfluid fraction (rho(s)/rho) and the specularity (S) of quasiparticle scattering of superfluid He-3 were measured as a function of temperature, pressure, and pore size by means of fourth sound propagation. Up to a pore size dependent threshold He-4 coverage, both rho(s)/rho and S remain equal to those for pure He-3. Beyond the threshold, both rapidly increase as He-4 coverage is increased. The enhancements vanish at pressures greater than some critical pressures depending on He-4 thickness and pore size.
