How will we know if it's okay?

我们怎么才能知道它靠谱呢
It's got to be continuous.

曲线必须是连续的
We're not going to have a problem with that

这完全不是个问题
because the computer is tracing it out this way;

我们使用的方法就能保证曲线是连续的
it's not going to be discontinuous.

不可能不连续
But the main thing is that it doesn't diverge,

最关键的问题是它不能走岔了
that it doesn't go to infinity.

它不能奔向无穷去
Okay, so let's just guess twenty-one kcal/mole.

现在我们就假设总能量是21千卡/摩
Why not?

有何不可呢
Okay, now you can already tell me something about

现在你们已经能想到
what the curve is going to look like.

曲线大概是什么样子了吧
Notice that at those two distances, between these two distances,

注意看这两点间总能量的大小
