The theoretical formula about vacuity in vacuum tube and pore-water pressure at the observation point was obtained in this paper by using equation of gas state and equilibrium equation.

The theoretical analysis on bubble mass transfer process was made by the non reversible thermodynamics. Non steady state, steady state and equilibrium state and changing regulation were discussed.

运用不可逆热力学原理，对气泡传质过程进行了理论分析，讨论了非稳态、稳态、平衡态的差异及其变化规律。

They do badly in a crisis, however, because their “dynamic stochastic” element only amounts to minor fluctuations around a state of equilibrium, and there is no equilibrium during crashes.

然而，一遇到经济危机，它就难以为继了，因为其“动态随机”要素仅能说明均衡状态附近的微小价格波动，在危机来临时却无均衡状态可言。

So that's a big help. And equilibrium happens when there isn't any possible change of state that would satisfy this.

这个非常方便，当所有的变化,都无法满足这个公式的时候,系统就达到了平衡。
