巴比伦没有理想,迦太基也没有。
本文前面所提出的问题没有理想的解决方案。
There is no ideal solution to the issues raised earlier in this article.
You're allowed Cv comes out here for this adiabatic expansion, which is not a constant volume only because this is always true for an ideal gas.
绝热过程写下,这个式子是因为它对理想气体都成立,并没有用到等容过程的条件,只用了理想气体的条件。
So, ideally what we did see was, in fact, it does have enough energy with the UV lamp, it wasn't a dramatic shift you saw because we didn't start very high and then it went to that stuck point.
所以,理想上我们所看到的,事实上,紫外灯没有足够的能力,因为我们没有从非常高开始,所以它没有一个特别显著的移动,然后它又回到了黏着点。
It only cares what temperature is. If temperature is constant, there's no change in energy.
如果温度是常数,能量就没有变化,对理想气体。
