if we think about electronegativity as a periodic trend we can just draw our nice periodic table here, and let's separate it into quadrants.

如果我们来思考一下电负性的周期性规律,我们可以把我们漂亮的周期表画在这，然后把它分成四个象限。

When I call or invoke a function, think of it as creating a local table.

当我调用一个函数时，想象一下它是在这里创建了一个局部表。

So, if we look on the periodic table, comparing, for example, s to o, if we have s it's below o, what happens to ionization energy as we go down a table?

那么，如果我们看周期表上，比较，比如，硫和氧，硫在氧下面，当我们沿着表向下看的时候,电离能是怎么变化的？

And, if you laid this out in a table, as Mendeleev did with his cards, you would find that the local maxima all occur roughly in the same horizontal position from the end points of the rows.

如果你们这些放到一张表格上去，像是门捷列夫用纸牌做的那样，你会发现局部的最高点,会出现在同一个水平高度,从这些行的最后一点。

And he says on page 884: A poet writes always of his personal life, in his finest work out of its tragedies, whatever it be, ; remorse, lost love or mere loneliness; he never speaks directly as to someone at the breakfast table there is always a phantasmagoria.

84页他说道：,诗人总写自己的生活，最好的作品总是悲剧，不管是后悔，失恋或孤独;,这是他不会在餐桌上讲的,总是有这样一种幻境。

I regard the last few weeks as politicians deciding we gotta do something to get this off the table of the agenda to something that has a political demand for it What they did, they could have done worse things, they could have done better things.

在我看来，一直到前几个星期,政治家们才觉得自己该做点什么了,不能继续把这件事束之高阁而迟迟不行动,而应当将其转化为一种政治诉求,至于他们所做的一切，已是既定事实，他们原本或许会做得更糟，但也有可能更好，这个很难讲。

I can read as alanine, for example, from this table and if I see a , I know it has to be alanine.

通过查表我知道GCU对应苯丙氨酸,如果我看到GCU,我就知道肯定会是苯丙氨酸

We know that ionization energy is going to increase as we go across the periodic table, so that means carbon has a lower ionization energy than nitrogen which is right next to us.

我们知道电离能会随着周期表,向右而逐渐变大，因此碳的电离能比旁边的氮要低一些,那么就像我说的。

You can see that as you fill up your periodic table, it's very clear. But also we'll tell you a pneumonic device to keep that in mind, so you always remember and get the orbital energy straight.

在你们填周期表的时候，非常清楚但是我们也要告诉你们,一个策略去记住它，所以你们总是记得,并得到连续的轨道能量。

So as we go across the row, and this is my beautiful picture of a periodic table here.

那么当我们沿着行向右走的时候，这是我漂亮的元素周期表。

And we know as we go across a row in the periodic table, what's happening is that z effective or the effective pull on the nucleus is increasing.

而我们知道沿着周期表的某一行向右看，有效核电量,或者说原子核的有效引力是在逐渐增大的。

So this is not even thinking about the other electron shielding, just if we think of the fact, all we need to think about is that the effect of going to a further away n n as we go down the table.

到现在我们甚至还没有考虑,其它电子的屏蔽效果，即使我们要考虑这个因素，我们需要考虑也就是,沿着周期表的某一列往下走，距离会逐渐变远,将起最重要的作用，actually，dominates,这一结果所产生的影响。
