This paper divides the equilibrium state of unstable system into two state: one is geometrical stable equilibrium state, the other is elastic stable equilibrium state.
本文将其受力状态分解为两部分，一是几何稳定平衡状态，二是弹性稳定平衡状态。
A state transfer matrix differential equation was derived from the three-dimensional equilibrium equations and constitutive equations of a homogeneous, isotropic linear elastic body.
本文从三维弹性力学最基本的平衡方程和本构关系出发，推导出状态传递微分方程。
