In principle, this value, this efficiency, can approach 1 as the low temperature approaches absolute zero.
这个值,效率,当低温热源的温度1,是据对零度时可以达到一。
If we add one to the return, then you've got a number that's never negative and we can then use geometric returns.
然后加上1,你永远也得不到一个负数,然后我们对这个值求几何平均
No, we can't. Because if l equals 1, we can not have m sub l equal negative 2, right, because the magnetic quantum number only goes from negative l to positive l here.
不行,因为如果l等于1,ml的值不可能等于-2,对吧,因为磁量子数的值,这时只能从-1到1
So I can now proceed to print it, change it, manipulate it, or what now.
这样我们就可以打印出来,或改变其值,对它进行操作,等等。
Now when you want to maintain good health, high peaks, high spikes in blood glucose and the insulin response that provokes is not a very good thing, and so the red line is a far healthier way to be than the yellow line is.
如果你想保持健康,血糖和胰岛素都出现高峰值,这对健康来说可不是好事,红线要比黄线更健康
We are constantly looking for values of F and we're constantly looking for responses or bodies to a known force.

Here's the problem with that technique, and by the way, a number of programming languages use this, including Lisp.
这会指向元素的值,然后对内存进行切分,关于这种技术有个问题,顺路说下。
You know, if you want to measure the potential energy of something in a gravitational field, you have to define the zero somewhere, right, because it's arbitrary. You can set it anywhere you want. It's the same with enthalpy.
你知道,如果你想测量重力场,中某种东西的势能,你需要,在某处定义一个零点,对吧?,因为势能的值是任意的,你可以把它设定在。
Which are actually things that take in a value and ask the computer to do something with it.
这其实也就是让计算机,对某个值进行某种操作。
That code says the following: the IF says, I've got an expression, I'm going to evaluate it.
代码的含义是这样的:,我有一个表达式,我会去对这个表达式求值。
And it's, again it's a macroscopic pretty big thing so typical might be 10 kilojoules per Kelvin, and that's pretty big, right?
相当大的数值,典型值大概,是10kJ/K,它相当大,对吧?,注意这里不是每摩尔?

我已经装了1号物品,1号物品的值是7,对不对?
So let's do c p 1 dot y, c p 2 dot y.
这不太好因为,两个地方的值都是一样的,对不对?
OK. Now, having said that, where should I pick to look in this list?
对不对?中值点?为什么呢?,你答对了但是为什么呢?
You read in a couple of values, you probably stored them away.
需要读进很多值,然后对他们进行存储。
Right. So this value right here.
对的,所以这个值就在这里。
If you have a sample with n observations, it's the summation I = 1 to n of xi/n--that's the average.
如果你有n个观测值,对Xi从i=1到n求和再除以n
OK. I get the two values in, what do I need to do, well, you sort of know that, right?
好,有了这两个输入值了,我接下来将要做的,你知道对不对?
Try it again. So, sure enough, changing the bias changed the price, and even changed it in the right direction.
我们再来运行一下,好了,很明显,这个偏向值改变了价格,而且方向也是对的。
I'm gonna keep as part of each stock, it's history of prices, which we can initialize, well, I've initialized it as empty, but that's probably the wrong thing, right?
我会把股票的历史价格,作为每只股票的一部分,我们可以先对它的历史价格进行赋值,好了,我先给它赋了空值,但是这样做可能不对,是吗?
On the other hand, if the value I'm looking for here- sorry, the value I'm looking for is smaller than the value I see here, I just need to look here. All right?
如果我的目标数比这个值要小呢?,我就在这边找就对了,对不对?,做完了这一步,我可以在下一步做相同的操作,假设我选中了这一分支?
In there, I want to make this distinction, this nuance: the evaluator is still going to be taking those expressions and using its rules to get a value, but it's not going to print them back out.
在这里,我想要做这么一个,细微差别:运算器依然会,对表达式,进行求值,但是不会,显示结果值。
There's nothing profound about this, other than the understanding that the details of how you set these things up can matter a lot.
只是说我们要理解,一开始设定时候的值,会对结果有很大影响。
And there's res. Never type kneeling. Right?
这里有很多有趣的中间值对不对?
Doesn't need to be, so, what should I do about the upper bound here?
不必改下边界值,因此,我该对上边界值做个怎么样的改动呢?
And the answer is, it inherits it from its value. OK.
答案是,它从它的值那继承了类型,对。
So when I'm done, I'm going to give the value back out. All right?
当它完成计算后,需要返回个值对不对?
Well, I could look at the value here, and compare it to the value I'm trying to find, and say the following; if the value I'm looking for is bigger than this value, where do I need to look? Just here.
然后把它和目标数做个比较,然后做出如下的判断:,如果目标值大于这个值;,那么我应该去哪找呢?对,应该在这里,对不对?不可能在那儿。
