So you need first to take the liquid helium and cool it below 53 degrees Kelvin before you can do the Joule-Thomson to cool it even further to make liquid helium.
我们首先需要,把温度江都53k一下,然后利用焦耳-汤姆孙实验,来继续冷却它。
You take your room temperature liquid helium and you cool it with liquid nitrogen to 77 degrees Kelvin, the new, you're not quite there yet 77k unfortunately right? Then you take hydrogen you cool it would liquid nitrogen to 77, then you can use your hydrogen gas.
首先要有常温的氦气,拿液氮把它冷却到77k,那个新来的7,你不坐在那儿,对吧?,然后用液氮把氢气降温到,然后就可以使用这个氢气了,想要用氢气来做焦耳-汤姆孙实验。
