  We report a study of nonequilibrium relaxation in a two-dimensional random
field Ising model at a nonzero temperature. We attempt to observe the
coarsening from a different perspective with a particular focus on three
dynamical quantities that characterize the kinetic coarsening. We provide a
simple generalized scaling relation of coarsening supported by numerical
results. The excellent data collapse of the dynamical quantities justifies our
proposition. The scaling relation corroborates the recent observation that the
average linear domain size satisfies different scaling behavior in different
time regimes.
