1·It shows further that solution of the special paradox in classical elasticity is just Jordan canonical form solutions in symplectic space under Hamiltonian system.

结果再次表明经典力学中的弹性楔佯谬解对应的是哈密顿体系下辛几何的约当型解。

2·This paper discusses some canonical forms of similar matrices in a general field F, gives a kind of rational forms in the field and a similar transformation from it to Jordan form.

讨论相似矩阵的一些标准型，给出一般域F上矩阵的一种有理标准形式，提供它变到若尔当标准型的相似变换。

3·In the case of the eigenvalues with the Jordan diagonal canonical form, a parametric method is proposed.

针对具有约当对角标准型的特征值情形，提出了一种求解该二阶振动矩阵方程的参数化方法。
