摘要：This paper presents a numerical model solving the inverse problem of
   intervals of elastic constitutive parameters,and a perturbation finite
   element technique with interval parameters and a Gridding Partition
   based colony algorithm are employed in the solution process.The impacts
   of nonhomogenity,radius of uncertain intervals,initial guess and data
   noise on the solution are taken into account,and satisfactory results
   are achieved in the numerical verification.
