Mr.Obama vowed to put one million plug-in hybrid cars on U.S.roads by 2015.

And in terms of equations that we use, it's sometimes easier to plug in the fact, since momentum is equal to mass times velocity.
在我们使用方程这方面,事实上有时是很容易代入的,因为动量等于质量乘以速度。
It's one thing to plug in all the numbers and say, "I know Newton's laws and I know how they work."
我们平时只是把数字代进公式,然后说,"我懂牛顿定律,也知道怎么使用"
You plug all of this in and you get 344 kilojoules per mole, which then sums to 608.
把这些都算上,我们得到344千焦每摩,与上面结果加起来是608千焦每摩。
I don't know if you know how a spark plug works, but for the electrical current to fly into operation in a spark plug, the two points of contact have to be gapped.
我不知道你们是否知道,火花塞是怎样工作的,在电流通入火花塞中使它运转之前,两个接触点之间需要有空隙。
So now, I need to plug the 24 in there.
将24代入。
z So the main idea here is z effective is not z, so don't try to plug one in for the other, they're absolutely different quantities in any case when we're not talking about a 1 electron atom.
所以这里主要的观点是有效的z不同于,所以不要尝试将一个插入到另一个,当我们不在讨论1个电子的原子时,它们在任何情况下是绝对不同的量子数。
What about the fact that-- We said there's a family of arguments, all of which have the general structure, inference to the best explanation, you need souls in order to explain feature F. Plug in a different feature F and you get a new argument.
这个事实怎么样,我们说过有一大类观点,它们有一些共同的结构,有关于这个最佳解释的推论,需要用灵魂的概念,来解释功能特征F,代入一个不同的,功能特征就会得到一个新的论点
Much like the opportunities in the word "plastic," I think it's useful to suggest that this sense of gapping a spark plug may have some relevance to our understanding of what goes on in this reading process.
就像说到“塑料“时的几种可能性“,值得一说的是,这种火花塞间隙的概念,可能与我们的阅读有关,它让我们了解到阅读过程到底是怎样的。
Of course, we have to also know how to plug in the numbers so we can pass all the tests, but it's good to understand the nature of the edifice set up by Newton.
当然,我们首先要知道怎么代数字,这样我们考试才能过关,但是如果能理解,牛顿的这一伟大杰作的本质就更好了
And it turns out that if we have a, for example, for s, a very large z effective or larger z effective than for 2 p, and we plug in a large value here in the numerator, that means we're going to end up with a very large negative number.
结果是如果我们有一个,举例来说对于s一个很大的有效电荷量或者,比2p大的有效电荷量,并且我们将一个较大的值代入计算器,那意味着我们最后会得到,一个非常大的负数。
So, we can just plug it in. Speed is equal to the distance traveled, which is lambda over the time elapsed, which is 1 over nu. so, we can re-write that as speed is equal to lambda nu times nu, and it turns out typically this is reported in meters per second or nanometers per second.
经过的距离和所花的时间,我们把它们带进来,速度等于经过的距离,也即是lambda除以,所花的时间,通常它的单位,是米每秒或者纳米每秒。
