We have a zinc plate up here, and we're going to -- in a minute I'll describe how we can probe if electrons are coming off of it.
我们有一块向上的锌板,我们将在一分钟内描述,我们是怎样探测出,是否有电子从上面射出的。
So we're going to look at a case, I'll use a new board, where products are differentiated.

I'm sure some of you have dealt with electrophoresis gels in the past and it's really just a slab of something like Jell-O where you can put a sample at one end of the Jell-O, your sample of fragmented DNA.
我相信在座肯定有些已经接触过电泳凝胶,真的挺像一块板状果冻的,你可以把一段样本放在"果冻"的一端,你的DNA片段样本
I mean sometimes if you have things that are a mixture of foods, like you go out for Chinese food or you have a casserole somewhere, or you have some dish of vegetables mixed together, how do you make sense of that when it comes to entering these things into a record.
我是说,有时候有一堆食物在你面前,如出去吃中餐,或你面前有一份大杂烩,又或者是很多蔬菜混合在一块,在输入饮食记录的时候,怎样才能让你输入的东西有意义呢
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。
