"What's on the table so far is quite limited and quite short term, when it needs to be large and long term,".

VOA: standard.2009.12.11

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。

Often what you'll see is not a table based on this definition, but something that's called the Pauling definition of electronegativity, but it's exactly the same idea and the same trend as this more numerical way to think about what the meaning of electronegativity is.

通常你看到的表格一般都不是基于这种定义的，而是基于,鲍林定义的电负性，但在意义上是相同的，并且满足同样的周期性规律,当和这种这种更数值化地理解电负性的定义,作对比时。

So this is my grades on the left hand table, but now let's look at what my pair will do, what my pair will get.

我的成绩写在左边的表格里,我们再看看我对手,她会得到什么成绩

Let me start out by putting what I think is a relatively controversial proposition on the table and that's that this investment management business, when stripped down to its bare essentials, is really quite simple.

让我从一个,相对争议的话题开始,投资管理业务,当剥离种种表象追溯到其本质时,其实非常简单

And that's all that's big enough to pass through or small enough to pass through. And if we go up even just one row on the periodic table to potassium, what we actually see is now that it's going to be too large, and, in fact, a potassium solvated with one water molecule won't go through our channel.

就是这样刚好大到它通过,或者说刚好小到它通过,即使我们再沿着周期表往下走仅仅一行到钾离子，我们看到的就将是它的个头太大了，实际上，溶解于一个水分子的单个钾离子,不能穿过我们的通道。
