| Abstract(in English) | It is shown that a three-fluid model, which was successfully introduced to explain microwave characteristics of high-T_c superconductors phenomenologically, is valid also to explain ones for low-T_c superconductors. In this model, two contributions of a residual normal electron in addition to a super and a normal electron in the conventional two-fluid model and of temperature(T-) dependence of momentum relaxation time τfor both these normal electrons are taken into account. Measured results of T-dependence of the surface resistance R_s for a Nb film with T_c=9.3K agree very well with an R_s curve calculated by the present model. Furthermore an improved two-fluid model, which corresponds to the case of n_ |
