So, you'll have a time, and you'll go to the same time on the Tuesday and on the Thursday.
你们会有时间的安排,你们会在周三和周四,相同的时间去上课。
It might take you a little longer to get through it, but I wanted you to have the same experience.
你们读的话可能要多花些时间了,但我希望你们也能体验相同的乐趣
Constant. Ooh, constant says, no matter what the length of the list is, I'm going to take the same amount of time.
这个算法用的时间是相同的,我不这么认为,如果我们创建一个十倍于以前大小的数组。
Okay, so 1 is a viable answer in some contacts that needs constant time, the same amount of time no matter what.
在需要常量时间的情况下,答案是1,不管怎样,总时间是,相同的。
That's why every-- development of every specific vaccine turns out to be different because they don't all follow exactly this kind of time course.
这就是为什么,每一种疫苗的发展都是不同的,因为疫苗诱导产生应答所需时间各不相同
By regular rate we mean that the amount of time that each chord holds is exactly the same; every chord holds for the same length of time.
如果变化频率规则,那么和声中每个和弦持续的时间长度是完全相同的;,每个和弦都持续同样长的时间。
The trouble is, you just don't know when that explosion took place, and since there are several periods in this general area that we're talking about now, in which something big happened, some great change takes place, it turns out different people want to have their explosion at different times.
问题是,你不了解火山爆发的,确切时间以及这种爆发,在这个区域又延续了很多个时期,这些时期发生了许多重大事件和重大变化,结果就是不同人对,火山爆发的时间推测各不相同
For example, if you started here and you did all this and you came back here, the average velocity would be zero, because you start and end at the same value of x, you get something; 0 divided by time will still be 0.
例如,如果你从这里开始运动,经过这个过程又回到这里,平均速度就是0,因为初态和末态的位移相同,你得到了什么呢,0除以时间还是0
You can actually say big O of 1, big O of 1 being constant time, the same number of steps.
其复杂度为O,表示时间是一个常量,所用的步数是相同的。
In '98, I forget which way, but one of the share classes 20% was at a 20% discount to the other and that persisted for several years, so you have economically identical things trading at different prices.
在98年,我不记得是为什么,一支这种类型的股票,比另一只股票便宜,而且这种现象持续了好几年的时间,因此你拥有经济意义上完全相同,但是却以不同价格进行交易的东西。
So we're to assume we can get to any piece of data, any instruction in constant time, and the second assumption we're going to make is that the basic primitive steps take constant time, same amount of time to compute. Again, not completely true, but it's a good model, so arithmetic operations, comparisons, things of that sort, we're all going to assume are basically in that in that particular model.
因此如果我们假设在恒定的时间内,我们可以取得任何一块数据,任何一种数据结构的话,我们要做的第二个假设就是,基本的原始操作计算花费的时间是恒定的,这个假设也不是完全正确的,但这个模型其实挺不错的,因此算法操作,比较,这一类的事情,我们在这个特定的模型中都假设是基本的,操作,花费的时间是恒定相同的。
