It is known that the irreversibility line and the transition
line between the so-called glass and liquid states of flux
lines are different, although those are closely correlated
to each other. This difference is speculated to be
associated with the distribution width of the flux pinning
strength. The two characteristic lines are analyzed as a
function of the distribution width of the flux pinning
strength using the flux creep-flow model for a Bi-2212
superconducting tape. Discussion is given on the difference
between the two characteristic lines.
