The stuff that's inside the reacting volume, and whatever's right around it there inside the big box, it's all going to heat up.
都会升温，对吧？,在反应容器里的东西,以及大箱子里的任何东西，他们都会变热。
-
So as you can see, as we escalate the problem difficulty, the difference between the good method and the not quite as good method gets bigger and bigger and bigger.
如你所见，当我们处理更复杂的,问题的时候，优良的算法,和并不那么好的算法之间的,差异会变的越来越大，这一点很重要。
-
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。
-
Think of anything else with the density goes down when it freezes, and think about where we would be if that wasn't the case.
想想有没有其他的物质,在降温时密度会变大，再想想如果不是这种情况,我们将会怎么样。
-
Diffusion mixes things very well, but as the size gets bigger, diffusion becomes very slow.
扩散作用使物质充分混合,但随着细胞变大后,扩散作用就捉襟见肘了
-
We're going to drop the pressure, the volume is going to go up.
我们会降低压强，体积就会变大。
-
When it was louder, the arm was moving to the right.
当声音变大的时候，手臂在向右移动。
-
But notice unlike a for loop, if you want to declare a variable or increment or decrement to variable, you've got to do that yourself.
但请注意不像for循环，如果你想声明一个变量,或者变大或变小一个变量，你需要自己完成。
-
- And we can think about why -- essentially we have fluorine and now we're adding another electron. So you can picture that fluorine is going to get larger in this case And that would be true for all of the negatively charged ions.
我们可以想一想这是为什么-,本质上来讲我们现在给氟原子加上了,另外一个电子,因此大家可以想象在这种情况下氟将变大,而且这对于其它负离子也是成立的。
-
What we really want to worry about is, as the size of the problem gets larger, how does this thing grow? How does the cost go up?
随着问题规模的变大，解决问题花费的代价是怎么增长的,因此我们将会主要地讲讲？
-
How does this thing grow as I make the problem size big?
也就是说当问题规模变大的时候,算法计算的时间会怎样增长？
-
Would it increase or decrease z effective?
它将变大还是变小呢？
-
This is because even though z, the atomic number is still increasing, we are also getting further away from the nucleus.
从有效核电量方面来想一想为什么，这是因为，尽管，Z，原子序数依然在变大，但我们同时也在离原子核越来越远。
-
So if we compare l increasing here, so a 3 s to a 3 p to a 3 d, what we find is that it's only in the s orbital that we have a significant probability of actually getting very close to the nucleus.
我们比较当ｌ变大的时候，从３ｓ到３ｐ到３ｄ,我们可以发现只有ｓ轨道,有很大的概率,非常接近原子核。
-
And when you're switching n's, you're actually getting quite a bit farther away.
而当你改变，n，的大小时，实际上每一步你都会变远了很多。
