So you sort of have a zero-base budgeting model of, "If we were a start-up, what would we do? How would we organize to deliver value to the customers?"

所以得有一个零基础预算模式，如果我们从头开始，我们该做什么,我们如何组织以带给客户价值“

That's going to presumably be given--mathematically if we gave it a number, we'd slap a zero on that.

如果用数学解释,给它一个数字，给它一个零。

And if that's equal to zero, that means that the Joule-Thomson coefficient for an ideal gas is also equal to zero. We're going to actually prove this later in the course.

说明理想气体的,焦耳-汤姆逊系数也等于0。,详细的证明过程,会在以后的课上给出。

- Just to give you another several fun facts -- and next week, once we've looked at your Problem Set "Zero Submissions," which, if you haven't filled it out yet, you'll see asks a few demographic questions, a few geek-type questions so we can get a sense of the students.

我给你们分享另外几个有趣的事实-,在下周，一旦我们看到你们的习题集上是,“零个意见书“，如果你们还没有填写那个习题集的话，你们可以问一些人数统计方面的问题，或一些古怪的问题，那样我们就能对学生有个初步的了解。

It's not even a zero-- or rather if I have less, you'll have less- that's a negative sum game-- or a zero sum game-- if I have more, you'll have less- it's a fixed pie.

甚至不是一个零…,或者我更少，你也会更少，那也是负和游戏-,或零和游戏，我更多，你就会更少-,饼就那么大。

If security selection is a zero-sum game, the amount by which the winner wins equals the amount by which the loser loses -winners and losers being defined by performance after a security selection that has been made -well, that sounds like a zero-sum game.

如果证券选择是一个零和博弈,赢方赚得的金额,等于输方赔付的金额,谁赢谁输取决于,双方投资在证券选择后的表现,这听起来确实像个零和博弈

The reason in our radial probability distributions we start -- the reason, if you look at the zero point on the radius that we start at zero is because we're multiplying the probability density by some volume, and when we're not anywhere 0 from the nucleus, that volume is defined as zero.

在径向概率密度里，我们开始,如果你们看半径的零点，我们从零点开始,因为我们用概率密,度乘以体积,而当我们，在离核子很近的地方,体积是，所以我们会在这里。

But if its south-north, this will represent zero.

那么，南北极磁性就代表。

but right now you're going to have to take it for granted. So, if the Joule-Thomson coefficient is equal to zero, just like we wrote, du = Cv dT du = Cv dT for an ideal gas, we're going to dH = Cp dT have dH = Cp dT for an ideal gas as well.

但是现在请你们应该把它看成理所当然的,所以，如果焦耳-汤姆逊系数等于零,就像我们写的，对于理想气体,我们也可以得到对于理想气体。

So in this experiment here, delta p is less than zero. You need to have this whole thing greater than zero. So delta T is less than zero as well. So if you're below the inversion temperature and you do the Joule-Thomson experiment, you're going to end up with something that's colder on this side than that side.

所以在这个实验中，Δp小于零,这全部都大于零,因此ΔT也小于零,所以如果在低于转变,温度的情况下做焦耳-汤姆孙实验,最后的结果是,这边的温度比这边低。

-- Else if n is greater than 4 and n is less than 6 -- 7 let's call it medium -- else if n is greater than or equal to 7, -- less than or equal to 10 -- let's call it "big" -- and if the user typed in zero or negative 10 or 20 or whatever, let's just use the all-inclusive else block and just say, "You picked an invalid number."

否则如果n大于4，并且n小于-,我们叫它为中间数--否则如果n大于等于，小于等于10--我们叫它为“大数“,如果用户键入了0或者-10或20或其它的，让我们用一个广泛的else子句，只需要说，“你选了一个非法的数字“
