Abstract: For  characterization of rearrangement class of a given function,a simple characterization of the rearrangement class weak closure of the characteristic functions is provided.At the same time,in ideal fluids,another derivation method on the configurations of steady vortices is given.

Key words: rearrangement class, weak closure, steady vortices, measure theory
