变量

The basic idea is: split the variables into smaller nonnegative quantities, then, collect the terms and see whether the coefficients all are nonnegative. The method has been used to prove symmetric polynomial inequalities for so many years that the origin is unavailable.

将各变量按一定方式分割成较小的非负量，将变量替换后的多项式合并同类项，然后看是否所有的系数都是非负的。

In this paper, the fundamental problems of the dynamic buckling in cylindrical shells are axial impact, torsion impact and coupling impact. The dual variables in symplectic space are gotten from energy function, and the Hamiltonian system is established.

本文针对弹性圆柱壳在轴向冲击、扭转冲击、轴扭耦合冲击及径向均布压力和轴向冲击载荷耦合作用下的动态屈曲问题，借助于系统的能量构造出问题的原变量和对偶变量，建立了系统的哈密顿体系。

When the Hamiltonian system is introduced into the research of dynamic buckling in cylindrical shells, the problem uses dual variables in Symplectic space instead of variables in traditional Euclidean space. The symplectic eigenfunction expansion method gives out an exact solution space. So many problems are solved, which can not find the solution in traditional methods.

将哈密顿体系引入结构的动态屈曲研究中，其意义在于将结构的动态屈曲研究从传统的欧几里得几何空间进入到由原变量和对偶变量组成的辛几何空间之中，从而使辛本征函数展开的直接解析法得以实施，这样就可以求解许多以往半逆凑合法无法求解的问题，并且所得到的解空间是完备的。

In the practical power system operation,the powers of generators and loads are changing constantly,and the state variables e.
