【 摘 要 】

In a modified ideal Bose gas model we derive an expression for the temperature dependence of the superfluid fraction in liquid He-4. This expression leads to a fit formula for the asymptotic temperature dependence that reproduces the data significantly better than comparable formulas. [S0163-1829(99)00906-6].
