where all the beats, the b-generation in the 50s gathered and they used to sell banned books.

It continues to confirm that some U.S.bombers, all the B-1 bombers, no longer have a nuclear weapons role,".

The B-1 is a strategic bomber that was not originally designed to provide direct air support to ground forces, which was the mission in this instance.

I mean if you chose Alpha, you're swinging from A to B-; and from Beta, swinging from B+ to C.
要是你选α,你的分数会在A到B-,选β,分数范围会在B+到C
-
"There were some problems with some tactics, techniques and procedures, the way in which close air support was supposed to have been executed in this case, such that, at least with one of the aircraft involved, a B-1 bomber, that plane because of how it takes its bombing routes had to break away from positive I.D.

This refers--this actually goes back to B.F. Skinner, a psychologist who flourished in the first half of this century.
这要追溯到B.F.斯金纳,一位活跃在上世纪前期的心理学家
-
Maybe the argument goes wrong by assuming that identity--when A is equal to B, it's always equal to B, no matter what.
也许这个论证就错在,假设了同一性,即当A等于B的时候,它总是等于B,无论情况如何
-
What happens when they're activated is they start to reproduce, they make more and more, and more B-cells.
激活后,免疫细胞开始增殖,B细胞变得越来越多
-
It says, in either case in general, t of b-- and this is where I'm going to abuse notation a little bit but I can basically bound it by t, 12 steps plus t of b over 2.
我可以用一个,比12+t的数代表,这里有点不准确的地方,具体的步数依赖于奇数偶数，但是你们可以看到在两个case中。
-
The next phrase, B-- is very similar, but here it takes the deviation-- And gets it back-- gets us back to the tonic.
下一乐句,B,与之前非常相似,但从这里偏离,又回来,回到主音
-
Finally, they got Harry Hamlin to do it, who was kind of a B-list sort of guy.
最后他们找了Harry，Hamlin来演，他是一个二线演员。
-
OK, in a few weeks, you're going to find out that we can calculate dH/dp from this equation of state, and you're going to find p out that dH/dp from that equation of state b-a/RT is proportional to b minus a over RT.
好，在接下来几个星期里,你们将知道从这个状态方程,可以计算出偏H偏p，并且你们会发现,从这个状态方程得到的偏H偏,正比于。
-
Let's multiply both sides by 2, I'll get 2q1* is equal to a - c over b - q1*.
等式两边同时乘以2,得到,2q1*=/b-q1
-
Now, what we learn, both from archaeology and from references in the Linear B tablets is that they engaged-- these cultures engaged in trade to a significant degree.
现在,我们从考古学,以及B类线形文字刻板中的线索得知,这些文明中具有相当多的贸易因素
-
The antigen has to be presented to helper T-cells, those helper T-cells have to stimulate a B-cell population to both proliferate and differentiate.
抗原需要被呈递给辅助性T细胞,这些辅助性T细胞需要激活B淋巴细胞,使其增殖和分化
-
Yeah. Actually, I think I want b minus k equal to 1. Right?
对，实际上，当b-k=1的时候就该停下来了对不对？
-
So this is a - c over b and this is a - c over 2b so this distance and this distance are meant to be the same.
这点是,/b,这点是,/2b,这两段长度应该是相等的
-
This is his Symphony No.5 in B-flat so let's listen to this.
我们要听的来自他的降B大调第五交响曲。
-
I personally don't like swings that much and it's the B-/B+ range, so I'd much rather prefer that to a swing from A to C, and that's my reason.
我不喜欢成绩波动很大的,比如B-/B+这个范围,所以我还是喜欢像A到C这样小点的,这就是我的原因
-
And then at the end of the process I have another whole step from B-flat back to C, and that gets me back to my octave in that fashion.
最后一步,从降B回到C是一个全音级,然后完成了整个八度
-
Well, go back to what I did before.
我会用a*a的b-1次方的形式来表达。
-
In the case of the helper cells they stimulate a specific population of B-cells to mature into antibody producing cells, and that antibody is generated against the antigen that stimulated it.
以辅助性T细胞为例,辅助性T细胞刺激特定的B细胞,使这些细胞成长为抗体分泌细胞,抗体分泌细胞产生大量的抗体,以消灭大量增殖的抗原
-
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, either stimulates the production of-- and differentiation of B-cells, to produce a specific antibody that can neutralize the virus, or stimulates the production of cytotoxic T-cells that can kill infected cells within your body.
所以,疫苗的刺激要么能够,促进B淋巴细胞产生和分化,以生成特定的抗体来杀灭病毒,要么刺激T细胞释放细胞毒素,杀死身体里被感染的细胞
-
If he enters the election and he wins the election then his payoff is B because he entered C, --sorry B because he won, C because he had to pay his election expense.
如果他参加选举并且获胜,那么他的收益是B,因为他参选,C,对不起,B,因为他获胜,C,因为他要支付选举成本
-
Because if B was just another word for, another way of talking about, A, then to imagine A existing but B not existing would be imagining A existing but-- well, B is just A--A not existing.
因为如果B只是,A的另一种表达方式,那么认为A存在而,B不存在就是认为A存在但,B,也就是A,却不存在
-
Cells share signals with each other, and that leads to activation of a specific cell population if we're thinking about a vaccine that produces antibodies, that leads to activation of B-cells, immature B-cells, which do two things.
细胞与细胞之间存在信号传递,而这将激活特定的细胞群体,如果是一些能够产生抗体的疫苗,抗体将会激活B淋巴细胞,幼B淋巴细胞,使其发生两种变化
