The forces must satisfy the conditions of equilibrium and produce deformations compatible with the continuity of structure and the support conditions.

所有力必须满足平衡条件并产生与结构连续性与支承条件相协调的变形。

In those cases, though, you'd have quite a reasonable equilibrium, spontaneously that is there would be a lot of reaction that went if you simply started under practical conditions and let it go.

你也会得到平衡，尽管在这种情况下你得到了一个，自发的，合理的平衡，这是在正常条件下进行的，许多化学反应的情况。

Under certain conditions, the equilibrium analysis is still a kind of powerful tool of analysis.

在一定条件下，均衡分析仍然是一种强有力的分析工具。

So I just want to use that again and again, starting from that, for various different sorts of conditions andderive the criterion for equilibrium in each set of conditions.

所以我将会一遍又一遍地使用这个公式，从这个公式出发，在各种条件了,推导出,任意条件下的平衡条件。
