long rotating ellipsoid while keeping its volume constant. Firstly，the displacement function is determined by the
principle of minimum potential energy and physical conditions. Then，according to the relationship among elastic
potential energy density，strain and displacement，the elastic potential energy is obtained by integral calculation，
and the beneficial discussion is made.
