The scaling of current-voltage characteristics is
investigated for a two-dimensional silver-sheathed
Bi-2212 tape wire under the magnetic field parallel to the
$c$-axis. It is found that the current-voltage curves are
approximately scaled on two master curves by normalizing as
predicted in the scaling theory.
The results are compared with the theoretical
analysis based on the flux creep-flow mechanism in which the
distribution of flux pinning strength is taken into account.
It is found that the theoretical result approximately
explains the experimental result on the scaling behavior and the
transition line. A discussion is given on the dynamic
critical index.
