Enthalpy is just u plus p V.

你想要的任何地方。

So we have dH/dT keeping pressure constant, is du/dT keeping pressure constant.

等于偏U偏T，p恒定加上，偏pv偏T，p恒定。

H=qp The u plus p V. Delta H is equal to q V.

括号里面的就是H，等于u+pv，Δ

du/dT constant pressure is the direct derivative with respect to temperature here, which is sitting by itself under constant volume keeping this constant but there is temperature sitting right here too.

偏U偏T，p恒定是对,温度的直接微分，而它本身对体积不变,保持它不变，但是这里也有一个温度,这就是偏U偏V，T恒定。

U It's u, because u is to q plus w right, heat and work, but it's adiabatic. So there's no heat, exchange with the environment, and it's constant volume, so there's no p dV work, right.

什么是零？是U，因为,等于q加w，热量和功，但这是绝热的，所以系统与环境间没有热量交换；,同时它是灯体的，所以也没有pdV形式的功。
