For the third case, arc power is constant, arc discharge time and occurring probability is very small therefore causing no gas ignition.

第三种情况是电弧功率在整个放电时间内基本不变，放电时间小，出现概率很小，不会造成气体引爆。

You're allowed Cv comes out here for this adiabatic expansion, which is not a constant volume only because this is always true for an ideal gas.

绝热过程写下,这个式子是因为它对理想气体都成立，并没有用到等容过程的条件,只用了理想气体的条件。

So for an ideal gas then, dH/dp under 0 constant temperature, that has to be equal to zero.

所以对于理想气体,偏H偏p在恒温下，等于。

nRT So, dp/dT, for our ideal gas, at constant volume, remember pV is nRT.

对于理想气体状态方程pV等于，所以对理想气体。
