It was at the Piper Alpha drilling structure in the North Sea.
VOA: special.2009.03.22
-
And, so the experiment was to bombard the foil with these alpha particles, and that measure what happens to them.
因此用这些阿尔法粒子,去轰击金箔，将会发生什么事情呢。
-
We broke up into groups, and each group designed its own toy and made an alpha prototype.
我们分成几个小组，每一组独立设计，并制作出一个玩具模型。
-
So this project was, let's see if we can detect any alpha particles by making a detector that swings around.
当你是本科生的时候，你们的导师会派一些,你们看上去很傻的工作,给你们干，现在这个工作就是。
-
Let's just check. If my pair chooses Alpha, then my choosing Alpha yields 0, Beta -3: so Alpha would be better.
我们来验证下,如果我对手选α,我选α得0,选β得-3,所以选α更好
-
Alpha particles are these helium nuclei, and they are the result of radioactive decay.
阿尔法粒子是氦核，它们是放射性衰变的产物。
-
It is the quality that we associate with being a kind of alpha personality.
就是这种质量,让我们将其与权势人格联结在一起。
-
How many people abstained? Not allowed to abstain: let's try it again. Alpha in this case? No abstentions here.
多少人弃权了,不带弃权的,再举一次,多少人选α,不能弃权
-
If my opponent chooses Alpha and I choose Alpha, I get 0; Beta, I get -1. So Alpha would be better.
如果我对手选α我选α,我得0,选β我得-1,选α更好
-
If he switched from gold to let's say iron, he also tried platinum, a number of different foils, he found that they count rate it still was 20 alpha particles per minute.
金箔的时候，计数率就变成零了,如果他把金换成比如说铁，他们还尝试了铂,还有一系列其他的箔片，他发现计数率还是每分钟。
-
So, what we've got here is a source of alpha particles.
我们已经有了一个阿尔法粒子源。
-
We detected a 132 000 alpha particles.
他们为什么要这么做？，我们知道。
-
So, they took away that gold foil and said is just the alpha particles hitting it some other way?
就是也许这是背景噪音,对吧？于是所以,他们把金箔拿走？
-
Who would choose Beta? Very few Beta's, but mostly Alpha's. Alpha, I think, is the right answer here but why?
好,谁会选β,很少有选β的,基本都选的是α,α应该是正确答案
-
First of all, the majority of the alpha particles were transmitted through the screen, OK, majority, vast majority.
第一点，大部分的阿尔法粒子,全都从屏幕穿透过去了，嗯，大部分的，绝大部分的。
-
So Alpha does better. But if my pair chooses Beta, then Alpha gets me -1; Beta gets me 1.
此时选α较好,但是如果我对手选β,我选α得-1,选β得1
-
The reason I chose Alpha, regardless of what my partner chose, I think there would be better outcomes than choosing Beta.
我选α是因为不管我对手选什么,我选α得到的成绩总会比选β的要好
-
Because I thought the payoffs - the two different payoffs that I could have gotten-- were highest if I chose Alpha.
因为我发现,如果我选α的话,我得到的两种结果是最优的
-
But if my pair chooses Beta then Alpha yields -1, Beta yields 1: in this case Beta would be better.
但是要是我对手选β我选α得-1,选β得1,此时选β更好
-
So by thinking about my opponent, by putting myself in my opponent's shoes, I realize that she has a dominant strategy, Alpha.
所以考虑到我的对手,站在她的立场上看,我发现她有一个优势策略α
-
Suppose I reason and say if we, me and my pair, both reason this way and choose Alpha then we'll both get 0.
假如我和我队友都这么想,如果我们都选α我们得到0单位效用
-
Right, so you should all have been choosing in this game, you all should have chosen Alpha.
对,在这次博弈中,你们应该都选α
-
So in both cases, no matter what the other person does, she receives a higher payoff from choosing Alpha, so she should choose Alpha.
这两种情况下,无论别人怎么选,她选α总能得到更好的成绩,所以她应该选α
-
And there he was able to identify the alpha particle as the helium nucleus.
他证实了,阿尔法粒子就是氦核。
-
For, as Rutherford has shown the assumption of the existence of nuclei, as those in question seems to be necessary in order to account for the results of the experiments on large angle scattering of the alpha rays.
因此卢瑟福,提出了原子核存在的假设，这些关于问题的假设对于,解释阿尔法粒子的,大角度散射是有必要的。
-
This is the analogy to the alpha particle.
这和阿尔法粒子类似。
-
Nevertheless, at least 90% of you chose Alpha here, and that's the right answer.
然而90%以上的人都选了α,选α是正确的答案
-
I'm sorry? Why did you choose Alpha? Just repeat what you said before.
你不是选了α吗,请再重复下理由
-
We had acknowledged that Alpha is a dominant strategy for my opponent so we must choose based upon, or knowing that my partner is going to choose Alpha.
我们发现了α是我们对手的优势策略,所以我们必须要根据,我对手会选α来做出选择
-
If my pair chooses Alpha then Alpha gets me 0; Beta -3.
如果我对手选α那么我选α得0选β的-3
