This is just an equality. I have a constant pressure dH process. This term here is equal to zero.

这是一个等式，这是个恒压过程，这项等于零，这意味着。

Adiabatic q equal to zero. It's also delta H 0 which is zero. The two didn't necessarily follow because remember, delta H is dq so p is only true for a reversible constant pressure process.

在这个过程中ΔH等于,绝热的所以q等于0，而ΔH也等于,这两个也不一定有因果关系,因为，记住，ΔH等于dq只有在恒压。
