不稳定平衡

In the range ab, the equilibrium is neither stable nor unstable, that is why it is called neutral equilibrium

在ab范围内，这个平衡既不是稳定平衡也不是不稳定平衡，这就是为什么叫做随遇平衡的原因。

本文用负离子配位多面体生长基元理论模型讨论了多型性晶体表面螺旋结构的形成，提出在多型性晶体中配位多面体呈层状分布，配位多面体的面为层的边界，上、下层负离子配位多面体不是呈镜象对称的，在三方晶系和六方晶系的晶体中是沿晶轴a、b错开，上、下两层负离子配位多面体体呈交叉对应，从而达到稳定平衡。

The fluctuation of internal property in a system is an unavoidable disturbance which does not cause change of the state for a stable equilibrium system.

处于稳定平衡态的系统，其内部物性量的涨落是一种不可避免的扰动，不会引起其状态的变化。

Eta Carinae, a star between 100 and 150 more massive than the Sun, is near a point of unstable equilibrium where the star's gravity is almost balanced by the outward pressure of the intense radiation generated in the nuclear furnace.

Eta Carinae，质量是太阳的100到150倍，这是一个不稳定平衡的临界点，也就是恒星的引力通常靠核反应堆所产生的强烈辐射制造的外层气压来平衡的。
