I can take a heat pack, like the kind you buy at a pharmacy. Break it up. It gets hot.
买来的热装罐在里面打破,它就变热了。
I have yet to show you the solution to a wave function for the hydrogen atom, so let me do that here, and then we'll build back up to probability densities, and it turns out that if we're talking about any wave function, we can actually break it up into two components, which are called the radial wave function and angular wave function.
我还没有给你们看过,氢原子波函数的解,让我现在给你们看一下,然后再来说,概率密度,实际上,对于任何一个波函数来说,我们可以把它,分解为两部分,分别叫做径向波函数,和角向波函数。
That's what you need for a phalanx, because to maintain the integrity of the hoplite line, you can't have bumps and grooves, and trees and rivers in the way; it will break things up.
而是方阵作战所必备的条件,为了维持重装步兵队列的完整性,就不能在坑坑洼洼,有树林有河流的地方布阵,这会把方阵打散
or at least one mechanism, I shouldn't say -- the only one-- one mechanism for doing that is going to be to add functions is that it's going to provide both of these things, so the first thing it's going to do is, it's going to let us break up into modules.
我们处理这些的机制--至少一种机制,我不会说只有一种,一种机制是在我们的语言中增加函数,函数的关键是它要提供分解和抽象,所以第一件要做的事,就是将代码分解为模块。
So when we write that out, we just write sigma 1 s squared, or we can break it up into its individual parts, there's no reason we can't do that as well.
当我们把这个写出来时,我们写sigma1s的平方,或者我们可以把它拆分成每个部分,我们没有理由不能这么做。
For example, in terms of the atomic theory of matter, at the time at the turn of the Century, the understanding was that atoms were the most basic constituent of matter, meaning you couldn't break atoms up into anything smaller - that was it, you're done.
例如在原子理论中,在19,20世纪之交的时候,人们认为原子是,组成物质的最基本粒子,也就是说你不能,把原子再分割了,就这样了。
You know, one famous tactic is--if you have an infantry force coming forward, you send tanks in it to break up the line of the infantry, so that you can defeat the infantry in that way.
最有名的战术是,如果有敌方步兵逼近,你把坦克派过去,破坏他们的步兵阵型,以这种策略对付步兵
