Because they would have started with the hypothesis, not that there existed a month, but that June was particularly likely.
因为他们是有了假设然后再开始做实验的,而不是说有一个这样特殊的月份,而是六月是一个特殊的月份。
Their memory improved significantly, so their intelligence level as taking by tests before and after compared to control group improved significantly after a single week.
他们的记忆力有明显改善,他们的智力水平,在实验前后进行测试,再与对照组相比,在仅仅一周后就有明显改进。
And so we can then say, OK, let's do this second expansion.
这么说,好,让我们再做第二个实验。
But let's run it again, as we've done with all the other tests.
但是让我们再来运行一下,我们做完其他的实验。
I'll show you the studies and then we'll briefly discuss what they mean.
先展示试验,然后再来简单讨论下实验的意义
It's tabulated in books, and this we can measure p in the experiment. Delta p here is the change in pressure from the left side to the right side, and we can put a thermometer, measure the temperature before the experiment and measure the temperature after the experiment.
这列在书上,这个量我们在,实验中也可以测量,在这里Δ,是从左边到右边的压强变化,我们可以放一个温度计,去测量实验前的温度,再去测量试验后的温度。
- And we could never do this-- and one could never do this experiment today but let me go through it with you and you'll apologize for its--some of its qualities.
我们不能再-,这种实验,如今再不能做了,我给你们从头至尾讲一下,因为实验中性别歧视的原因,我再次道歉。
We use a liquid helium. And so in order to make a liquid helium, you can't take helium at room temperature and do this, because if you did, you would just heat it up, because the room temperature is above the inversion temperature, so Joule-Thomson would heat up the helium.
为了得到液氦,不能再常温,做这个实验,否则就是加热氦气,因为室温高于它的转变温度,所以焦耳-汤姆孙,实验会加热氦气。
