被冰川锁住的空气气泡可以证明温室气体排放水平的上升,这已被作为“人类时代”开始的证据。
The rise in the level of greenhouse gases, which can be demonstrated on the basis of air bubbles trapped in glaciers, has been proposed as evidence of the beginning of the "age of man."
同时发现N2气氛下产生的气体中烃类和一氧化碳的体积百分比明显高于空气气氛下的百分比,气化工况对有机物的处理比较充分。
The volume percentages of hydrocarbon and CO in generated gas are higher in N2 atmosphere. Gasification is more efficient in organic waste disposal.

Furthermore, the sections are also moved forward. The volume percentages of hydrocarbon and CO in generated gas are higher in N2 atmosphere. Gasification is more efficient in organic waste disposal.
dT/dp is mu JT. So for a real gas like air, this is a positive number. It's not zero.
所以对于像空气这样的真实气体,这是一个正数,不等于零。
And if you put this in the well-ventilated area, if you prepare this outside, the h c n gas will actually be released into the air, so you're safe, you can eat it later.
而如果你把它们放在通风良好的地方,在室外处理,那么氰化氢气体,将会被释放到空气中,这样你就安全了,过后就可以吃了。
You've just done an adiabatic compression of the ideal gas, you can pretend there is an ideal gas.
这就是对理想气体的,绝热压缩,---我们把空气近似作为理想气体处理。
