In my in my area of research, it's common for us to want to process about 100 images a second in order to get real time display. Each image has about a million elements in it. I 've got to process about a half a gig of data a second in order to get anything out of it.

在我们的研究领域内，我们经常要在一秒钟内处理大概,100张图片以获得实时显示,每个图片大概包括了100万像素,因此我必须在1秒内,处理半个G的数据,来获取我想要的。

Let me first ask you this, is this a reversible or in irreversible process? Right, let me add one more piece of data here which I said in words but which is actually important to write down before doing the problem.

让我先问你们，这是可逆过程,还是不可逆过程？好,让我加上一点简要的,但是很重要的前提,【p1>p2】这是可逆的吗？

That is basically saying, given some collection of data, I want to have again a looping mechanism, where now my process is, walk through this, the collection one element at a time. And for that, we have a particular construct, called a FOR loop.

现在我的过程就是,通过一个个访问这个集合中,的元素的方式，来遍历这个集合,为了达到这个目的，我们有一个特定的结构，成为FOR循环。
