This is equal to zero. So this irreversible process this Joule-Thomson process, is a constant enthalpy process. Delta h for this process is equal to zero.

等于0。所以这个不可逆过程,也就是焦耳-汤姆逊过程,是一个等焓过程。

stdio c So somewhere there's standard IO dot C, stdio h somewhere they're standard IO dot H, but, for me, right now, the only file I need to know about is the dot H, -- because what Sharp include really does -- it's what's called a preprocessor directive.

所以某个地方有一个，现在对于我来说它们是，我只要知道那个，h文件，因为Sharp包含的-,叫做预处理指令。

For example, if t* is the time you hit the ground, then t* satisfies the equation h - 1/2 g ^2 = 0.

例如,如果在 t* 时刻落地,那 t* 就满足等式 h - 1/2 g ? ^2 = 0

We also know how to figure out the energy of this orbital, and we know how to figure out the energy using this formula here, which was the binding energy, -Rh which is negative r h, we can plug it in because n equals 1, so over 1 squared, and the actual energy is here.

我们知道如何算出,这个轨道的能级，而且我们知道如何,用这个公式,算出能量，也即是结合能，等于，我们把n等于1代进来，所以除以1的平方，这就是能量。
