it induces Nash behavior in each sub-game.

它在每个子博弈里会引发纳什行为
I think the battery is going on that.

可能是电池出问题了
Shall I get rid of that.

我可以不用这个吗
Okay, I'm going to shout.

好的我要大声讲了
Can people still hear me?

你们还听得见吗
People in the balcony can they hear me? Yup, okay

在楼上的同学能听见我吗好的
So we're going to have to see if we can sustain Nash behavior

我们要看看我们是否能在子博弈里
in each sub-game.

持续纳什行为
So let's start with the sub-games associated with the second period.

让我们先从子博弈与第二阶段的联系开始
Technically, there are nine such sub-games

从技术方面说根据之前的不同情况
depending on what happened in the past,

可能有九个不同的子博弈
depending on what happened in the first period.

根据博弈第一阶段的不同情况
