在恒温过程中，借助箱内控温器自动控温，不用人工管理。

During the constant temperature process, the temperature will be controlled automatically by the temperature controller in the oven, without manual operation.

从第三点到第四点，这也是一个理想气体的，恒温过程，这次不用你们集体回答了。

Now going from three to four right, so we have another isothermal process for an ideal gas, so I won't try to make you sing again so soon.

从一点到二点的，的积分。，from, one, to, two, of, p, dV。，这是理想气体，恒温过程，好的。

So it's, this is just the integral PDV And it's an ideal gas, isothermal, right.

So we're going to start at one, T1 and this is going to be in isotherm at temperature T1, and all the paths here are going to be reversible.

我们从一开始，这是个绝热恒温过程，温度是，所有路径都是可逆的。
