Our report earlier this month about the design of the American flag helped Anhthu Nguyen in Vietnam settle an argument: Now I know the meaning of the stars on the American flag and there are fifty stars.

But the things we were trying to stress were that it's an important design decision when you are coming up with a piece of code, as to what kind of efficiency your code has.

但是我们这里要强调的是,当你写代码的时候,决定你的代码的效率的很重要的事情，就是你的设计决定。

And then I gonna ask you to begin to design an approach, give me some recommendations that we can take forward and put into the new courses that we are gonna be developing.

然后我会让你们,构思一种方式，希望你们给我一些,能够实施的建议,并将其运用于,我们正在开发的新课程。

So again, if you do a calculation where you're close enough to the ideal gas and you need to design your, if you have an engineer designing something that's got a bunch of gases around, this is a useful thing to use.

要研究近似理想气体的表现时,这个方程非常有用,下面再来看一个，对我们来说最有意思的,实际气体状态方程：,范德瓦尔斯方程。

Now, if you're an engineer, and you use the ideal gas law to design a chemical plant or a boiler or an electrical plant, you know, a steam plant, you're going to be in big trouble.

比如说锅炉，蒸汽机,我们会遇到一个大问题：,我们设计的机器将无法运作，因为对大部分实际气体。
