And if you have your calculator all set up as you love and you don't want to change it, then maybe you should just go and get an $8.00 scientific calculator that doesn't have any of the graphing functions, because you don't actually need them, so that's a better option for you, you can do that as well.
如果你的计算器里已经按照你的喜好编好了,而你又不想改动，那么或许你可以,去再买一个八美元的科学计算器,它没有任何绘图功能，因为实际上你也用不到这些，所以这对你来说是一个更好的选择，你也可以这样做。

Then we would be able to change our equation to make it a little bit more specific and say that delta energy here is equal to energy of n equals 6, minus the energy of the n equals 2 state.
第一激发态，我们就可以把方程,变得更具体一点，能量差,等于n等于6能量，减去n等于2的能量。

It expands. You change your constraints on your system, you heat it up some more, then you take the heat source away, and you put it back in contact with the atmosphere. And you cool it a little bit, change the constraints, cool it a little bit more, and heat, and you've got a closed cycle engine.
让它与大气接触冷却,改变约束，使它继续冷却，然后又再次加热,这就是循环热机，我们以前也研究过，更复杂的机器。
