Discarding any assumptions about displacement models and stress distribution, the state equation is established for the axially symmetric problem of orthotropy.
抛弃任何有关位移或应力模式的人为假设，在轴对称情况下导出正交异性体的状态方程。

Based on the dual variables, the Hamiltonian system theory is introduced into plane orthotropy elasticity, the transformation from Euclidian space to symplectic space is realized.
