And as an added incentive for you to pay attention, I'm going to warn you that this particular simulation will appear in the final or a variant of it.

作为提高你们注意力的激励，我要警告你们,这个特殊的仿真程,或者它的变种会再期末考试出现。

And so, there is the distinction between fixed schedules versus ratios, variable schedules and ratio versus interval.

因此，在固定时程与变化时程之间,以及在比率与间隔之间，存在着一些区别。

So let's find out what the time is.

现在来解方程

Keep in mind we do have this p orbital here and it's coming right out at us. And this p orbital is here, but it's empty, it doesn't have any electrons in it, that's why we don't have to worry about it in terms of getting our electrons as far away from each other as possible.

他们程120度角互相远离,这样它们离得最远，记住我们这里确实有个p轨道，它朝向我们，这里有个p轨道，但它是空的,里面没有电子,这就是为什么我们在考虑。

Real life for both humans and animals involved cases where the reinforcement doesn't happen all the time but actually happens according to different schedules.

在现实中，人类和动物,并不总是不停的得到强化,但实际上强化则是根据不同的时程出现的。

The way the physics works is you will find some laws of motion in mathematical form, you put in the initial conditions of whatever, you solve the equations, and the answer that comes, you have no choice.

在物理问题中,你可以用数学方法得到运动定律,你代入初始条件,然后解方程,获得答案,你别无选择

And fixed versus variable speaks to whether you give a reward on a fixed schedule, every fifth time, or variable, sometimes on the third time, sometimes on the seventh time, and so on.

固定与变化则是相对于,你是否根据固定时程给予奖励而言的，每五次就给予奖励，或者是变化的，有时候在第三次上给予奖励，有时候则在第七次上给予奖励。
