Let's assume, for sake of argument, the thing I'm looking for is bigger than this. In that case, I'm going to throw away all of this, I'm going to hit that bottom line of that code.

让我们假定不是，假定要找的元素,比这个大，在这样的情况下，这些都擦掉，我要运行到代码的最后一行。

Pulling this lever or pushing the button would actually rotate the paper enough so that you'd be on a new line and it would also move the little imprinting head that prints the letters of the alphabet and such all the way to the left.

拉杆或按下按钮会让纸翻一下,这样你就能在新的一行上打字了,同时移动打印字母的,压印头,这样也能移到最左边。

Similarly we see as we go down the table, so as we're going from one row to the next row, so, for example, between helium and lithium, we see a drop; the same with neon to sodium, we see a drop here.

同样地，我们来看看沿着周期表往下走，当我们从一行到下一行时，比如，从氦到锂，我们看到了一个下落;,从氖到钠也一样，我们看到这里有个下落。

The next line says if the weight of i is greater than a w, well then I know I can't put it in.

下一行说的是,如果i的重量比a，w大，好吧，我知道我不能把它放进去。

So this first line of code, and some of this again we'll be rehashed but at least you can delight in the awkwardness that is this demonstration.

因此，第一行代码，有些地方我们需要重新处理下,但至少看到这次,笨拙的演示你会很高兴。

Available at the Harvard Coop. Alright, next line.

在校园里可以买到，好的，下一行。

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。

So if you've ever seen or used an old school typewriter, you might recall that when you're typing something out on an old mechanical typewriter, - when you like hit the char-- when you hit the enter key to move the head back to the left hand side to the next line or you would pull down some lever, it was really a two part process.

如果你们有谁曾经看过或用过老式打字机，可能还记得，当你在,这种老式打字机上打字的时候，当你-,敲入回车键，跳转到,下一行的最左边，或者,拉一下杆，这个需要两步走。

Even though this looks like what the out-- this looks like the output you want, "Oh, hi world" and then everything else should go on the next line.

即使这样看起来和你-,想要的输出“Oh，hi，world“没啥两样“,仅仅只是把其他代码往下挤了一行。

- There's no backslash n -- that would have forced the cursor on to the next row.

但没有“反斜杠n“,反斜杠n是用来使光标移到下一行的。

If n is greater than zero, I decided I would say, "You picked a positive number, backslash n," so put the cursor on the next line, else if n was not less than zero, I say, "You picked a negative number, backslash n."

如果n比0大，我就决定来说：,“你选择了一个整数，反斜杠n“，所以你把光标,放在下一行，另外如果n不小于0，我说：,“你选择一个负数，反斜杠n“

let's look at the next one here, first or is that second line?

或者说是下一行，好的，如果last减去？

You can imagine having many lines of code where all of a sudden your closed quote is on the next line all the way on the left.

你可以想象一下，这有很多行代码,突然一个后引号,移到下一行最左边。
