As far as we know, there is no systematic method available in the references for the exact controllability of semilinear systems so far.

我们方法的关键是将半线性系统的精确能控性问题转换成它的线性化系统对偶系统的能观性估计。

In detail, it has more strict antitheses in sentence structure; mingles more rhythmic sentence in sound structure; uses the skillful changing rhythm in rhythm structure; and employs more accurate allusion in modification.

其中比较突出的是：在句式上，对偶更精严；在声律上，杂以更多的律句，律化程度更高；在韵式上，娴熟的转韵技巧；在修辞上，用典更多、更精切。

Analysis of tube-in-tube structure of variable cross-section in torsion;2. By assuming the structure to be continuous,the Hamiltonian dual system of coordination analysis is established for tube-in-tube structure s,in which the shears and flexures of the inter and the outer tubes are considered as Timoshenko beams.

在结构连续化假定的基础上，将内筒和外筒视为铁摩辛柯梁，同时考虑内筒和外筒的剪切与弯曲变形，建立了筒中筒结构协同分析的哈密顿对偶体系，导出了相应的状态空间方程，其系统矩阵具有辛矩阵的特性，可用精细积分法求该体系的高精度数值解。
