And then we're going to look at that Nash Equilibrium and you're going to think, how does that compare to what I saw in the Cournot case we solved.
最后再看一下那些纳什均衡,你们要去思考,那跟我们学过的,古诺模型比较有什么异同
Now, if we go back to our Carnot cycle which is a set of reversible paths, it's useful to compare this to what happens in an irreversible case.
如果回到卡诺循环,它是由一系列可逆过程组成,我们将它,和不可逆过程的情况相比较。
We're going to compare this with my payoff from choosing 2 against the other candidate choosing 1.

We'll start with talking about the shape, just like we did with the s orbitals, and then move on to those radial probability distributions and compare the radial probability at different radius for p orbital versus an s orbital.
想我们对待s轨道那样,我们先讨论p轨道的形状,然后是径向概率密度分布,并且把s轨道和p轨道在,不同半径处的径向概率做一个比较。
