I go to B.B. King's all the time. And sit there, listen to the jazz.
我几乎每次都去B.B. King的演唱会,就坐在那儿,听着爵士乐曲。
Minus p, right? But in fact, if you go back to the van der Waal's equation of state b here's RT over v minus b.
再减去p,对吗,但是实际上,如果你代回范德瓦尔斯气体的状态方程,这里是RT除以摩尔体积减去。
And in the even case, I'd square, divide by half, call this again: in the odd case, I go b minus 1 and then multiply by a.
就直接求a的平方的二分之b次方,如果是奇数的话,就去求a的b-1次方乘以a,以此递归下去。
You can tell if you're at all experienced with it very easily, if you go--let's say to the year 900 B.C.
而如果你对此比较熟悉的话很容易看出来,如果你去--假定去公元前九百年
Does it go in the path of A, or does it go in the path of B?
是沿A路线飞出,还是沿B路线飞出
I got to go up to G and then another whole step up to A and then another whole step up to B.
上升到G,然后再一个全音级上升到A,再一个全音级上升到B
So that means Star B go to B so where is B?
它的意思是*B,定位到B,那么B在哪里呢?
Now, these Th-cells, helper T-cells, go on to stimulate B-cells, and it's these B-cells that become the mature antibody producing cells that make quantities of antibody that fill up in your body.
这些辅助性T细胞,进一步刺激B淋巴细胞,从而使这些B淋巴细胞,逐渐发育成成熟的抗体生成细胞,可在体内产生大量抗体
So basically we're saying yes, we can go from point a to point c without ever going through point b.
所以我们说的是我们可以从,a点不经过b点而到达c点。
So I take 2 plus 3 b steps to go through this loop OK. So if b is 300, it takes 902 steps.
好,如果b是300的话就是902步,如果b是3000那就有9002步。
t In the b even case, again I'm going to let t of b be the number of steps I want to go through.
如果b为偶数,那么我还是要用,来代表解决这个问题需要的步骤数。
Let me go ahead and do the same thing with B.
让我们继续对B做点什么。
b OK. In this example I'd use b. All right, as b get-- b is the thing that's changing as I go along here, but it could be things like, how many elements are there in a list if the input is a list, could be how many digits are there in a string if the input's a string, it could be the size of the integer as we go along. All right.?
好,在这个例子里我会用,因为b是一直在变的东西,但是也可能是如下情况:,如果输入是数组的话,变化的就是数组的元素数,如果输入是字符串的话,变化的就是字符串的长度,如果是integer的话,可能就是这个数的大小,对不对?
Well, go back to what I did before.
我会用a*a的b-1次方的形式来表达。
So instead you'd have to maybe if you start with wavelength, go over there, and then figure out velocity and do something more like kinetic energy equals 1/2 n b squared to get there.
这时你要先从波长开始,到这,然后算出速度,然后像动能等于1/2nb平方得到这。
b times. So I've got to go 3 b steps. All right I've got to go through the loop b times I've got three steps each time, and then when I pop out of the loop, I've got two more steps. All right I've got the initiation of answer and the return of it.
好,我一共执行了b次循环,每次循环内部进行了三次基本操作,当跳出循环后还有两个基本操作,因此这个初始的答案就是,2+3b次基本操作,来完成这个循环。
