摘要:
当研究分支点的失稳时，理论上特征值数与其自由度相同。体系的总势能Π是位移ｙ的实对称二次型，可用图解方式明确地表达在不同荷载阶段其能量特征与数学特征一一对应的关系，对二次型的几个定义域赋予明确的物理意义。
Abstract:
When the disability of the branch point, the theoretical characteristic value is the same as its freedom. The general energy of the system is a solid secondary type of displacement. It can be clearly expressed in a diagram to clearly express its energy characteristics and mathematical characteristics in different load stages. It gives clear physical significance to several definition domains in the secondary type.
