However, the thing to remember is, when you look at heats of reaction under those conditions it's all well and good.

相反，需要记住，当你需要知道反应中放出的热量时,这些量是很有用的。

So again, when we check these, what we want to see is that our z effective falls in between the two extreme cases that we could envision for shielding.

所以当我们再一次检查这些时，我们想看到的是,有效电荷量处于两种极端案例中,这两种极端案例。

I tie a spring to my back and I anchor it to the wall and see how much the spring stretches before the two forces balance.

我把弹簧一端系在背后,另一端固定在墙上,观察两个力平衡时弹簧的伸长量

But you know, when people eat pancakes it may not be this extreme, but still, there are a lot of things that-- where the portion sizes are misestimated.

但当人们吃薄煎饼时可能没那么夸张,但仍然,量非常大,每日摄入量被完全错估了

At least I don't have those. But what I've done is to excerpt some of the texts earlier in the term-- and actually there's so that it's a little bit lighter after break, when we're doing those long novels.

至少我没有列出那些,但我已经做完的是,在放假前当然会有稍多的阅读量，假期过后我们再读那些长篇小说时就会轻松一点。

And when we're talking about the amplitude of the wave, we're talking about the deviation from that average level. So, if we define the average level as zero, you can have either a positive amplitude or a negative amplitude.

当我们讨论一个波的振幅时,我们说的是偏离平均位置的量,如果我们把平均位置,定义为零的话，那幅值不是,正的就是负的，有时候人们在。

So it looks like not too many more than half of you got this correct, so make sure you can look at your periodic table and figure out how to think about ionization energy in terms of z effective, not just in terms of memorizing what that trend is.

看起来只有一半多一点的人,做对了，所以请大家务必做到能够通过观察周期表,并在考虑电离能时,从有效核电量的观点出发，而不是仅仅依靠记住这个规律。
