So the triple point is liquid solid, gas, all in equilibrium.

气态，固态，三相平衡,你可能会想。

I could have that path be very slow and steady, so that at every point along the way, my gas is an equilibrium.

我可以很慢，很稳定地经过这条路径，因此在这条路径上的任意一点，气体都处于平衡态。

If I've got a gas in a container, the pressure of the gas has to be the same everywhere in the container, otherwise it's not equilibrium.

如果把气体装进容器里，容器内各处气体的压强,应该是一样的，否则它就不是平衡的。
