In this case, it's called the ionization energy, plus whatever kinetic energy we have left over in the electron.
在这种情况下,它就是电离能,剩余部分将转化为,出射电子的动能。
So we can now take this expression and rewrite it under the condition of du is equal to zero.
我们利用这个公式,并在du=0的条件下将它重写。
And if you just look at the numbers, you can see how it cuts in from one side and then the other side as it keeps narrowing that range until it gets down to the place where there are at most two things left, and then it just has to check those two to say whether it's there or not.
你能看到他是如何不断的,从一个大的范围被拦腰劈开,知道最终只剩下两个数字,然后就只需要,比一比就知道结果了,将它同线性查找比较下。
What he does as you know is takes over a company and shakes them up and in some cases is accused of stripping their assets.
就像你们知道的那样,他所做的,就是接管一个公司然后将其整顿改组,同时,在有些情况下,剥削它的资产。
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。
