Query: Free Entanglement Measure   In this paper, based on the classfication of multiparticle states and the
original definition of semiseparability, we give out the redefinition of
semiseparability and inseparability of multiparticle states. By virtue of the
redefinition, entanglement measure of multiparticle states can be converted
into bipartite entanglement measure in arbitrary dimension in mathematical
method. A simple expression of entanglement measure is given out. As examples,
a general three-particle pure state and an N-particle mixed state are
considered.
