是条绝热路径，而上次你已经看到，沿着绝热路径温度和体积，的变化有这个关系。

And you already saw last time there was this relationship between the temperature and volume changes along an adiabatic path.

要实现这点，它就不会是绝热的，对吧，如果我想做到这点，我需要一个加热元件或什么制冷的东西，这样我才能让温度变化。

Now to make that happen, it's not adiabatic, right. If I wanted to do that, I'd need a heating element or something to cool, so I could make that temperature change happen, right.

采用数值差分法可以求解出绝热层内部温度变化规律，从而推出储罐内液体的温度和压力的变化规律。

The equation was solved with the finite difference method and the variation of the temperature in the insulation layer was concluded.
