Remember the Joule expansion.

回想一下焦耳膨胀。

What is the energy unit in SI? The joule.

国际单位制中的能量单位是什么，焦耳。

The Joule-Thomson experiment is irreversible.

实验是一个不可逆过程。

Now for this experiment, this is a constant enthalpy experiment for the Joule-Thomson experiment, this is equal to zero.

对于这个实验，焦耳-汤姆逊实验,是一个焓不变的实验,焓变化等于0，所以我可以。

Real refrigerators actually work with liquids that go into gases so use the latent heat of the liquid, so it doesn't really work like the Joule-Thomson expansion. So this is real.

液体变成气体来工作,以运用液体的潜热，所以这不是,真正像焦耳-汤姆逊膨胀一样工作,这是真实的气体，不像焦耳。

It turns out that this quantity here, which is called eta of J the Joule free expansion parameter, is not quite zero.

这个量后来被，称作焦耳膨胀系数,其实并不等于零。

Boutique properties like the Soho House were the first to get in on the action, and other hotels followed suit, from Hotel Frasano's Phillipe Starck-designed rooftop pool in Rio de Janeiro to the Joule in Dallas, where part of the pool hangs off the building.

The Eureka moment has given way to a more gradual evolution of ideas as global teams of both scientists and engineers replace the often isolated and lucky inventions of the likes of Thomas Newcomen, James Joule and Michael Faraday, he states.

Joule was founded specifically to sidestep the failures of previous biofuel companies, particularly algae-based biofuel efforts.
