So one thing that distinguishes that equilibrium

我们现在所说的这个均衡与
from the equilibria that we were just looking at is

之前所说的那两个均衡的不同之处在于
sometimes it's weak, whereas the other ones are strict.

这个是弱均衡而那两个是严格均衡
What do we mean by that?

这是什么意思呢
If we deviate away from this exactly mixed equilibrium,

如果改变这个混居的均衡
roughly speaking, a little bit of hand waving here,

注意我的手势和我说的内容
but roughly speaking we're exactly indifferent.

大体而言我们对此并不关心
It's true, that's not strictly true

这一点是正确的但不是完全正确的
because I guess by ourselves moving

因为如果只有我自己搬家了
we're changing the balance a little bit,

我们只能稍微改变均衡
but nevertheless we know if I smooth out the top we'll be exactly right.

如果我悄悄溜走了也就完事大吉了
So at that mixed equilibrium,

这是一种混居的均衡
