离散系统平衡稳定性的能量判别准则

The Energy Differentiation Criteria of the Equilibrium Stability of Disperation System

结合力学系统平衡的三种形式 ,讨论判别力学系统平衡稳定性的静力学准则、动力学准则和能量准则 .给出了离散系统平衡稳定性的能量判别准则的具体形式 .

This article, in the light of the three equilibrium forms of the mechanic system, discussed the stastics, kinetics and the energy criteria of the differentiation of the mechanics equilibrium stability. On the basis of this, it gives the specific forms of the energy differentiation criteria of the disperation equilibrium stability.
