Query: Critical Current of the Spin-Triplet Superconducting Phase in
  Sr$_2$RuO$_4$   There have been two different proposals for the spin-triplet order parameter
of the superconducting phase in Sr$_2$RuO$_4$; an $f$-wave order parameter and
the multigap model where some of the bands have the line node. In an effort to
propose an experiment that can distinguish two cases, we study the behavior of
the supercurrent and compute the critical current for these order parameters
when the sample is a thin film with the thickness $d \ll \xi$ where $\xi$ is
the coherence length. It is found that the supercurrent behaves very
differently in two models. This will serve as a sharp test for the
identification of the correct order parameter.
