A similar process occurs on a much smaller scale to gas surrounding a single star, forming the bow-shaped arc seen near the upper left side of the Cone.

类似的过程以小得多的规模发生在锥状星云左上方的一个恒星周围，形成了一个弧形光晕。

Third process: After operated by the back forward gas baffler, the paper reciprocates to the drum of the third layer to perform flanging of the front side.

第三个过程：纸张经后推气挡板之作用，再往复至第二层滚筒完成前边折边。

But now, so this is where the refrigeration comes in. So if you take a gas, and you're below the inversion temperature and you make it go through this irreversible process, the gas comes out colder from that side than that side.

这就是冰箱的原理,如果在低于转变温度,的情况下我们将气体经过,这个不可逆过程,气体出来的温度将比这边低。
