It is generally accepted that a hadron is an extensionable object. Naturally, the viewpoint that ahadron can be deformed is expected. In this paper, we discussed this problem. If the motion of a straton in a deformed hadron obeys the harmonic osciallator-potential of the SU (3)--symmetry deviating from spherical, then we can derive the mass spectrum of the family of mesons and baryons with satisfactory. The hadron is of ellipsoidal symmetry and it is predicated that there will exist the Volume and deformation...
