The results show that the reflection coefficient near the wall is about 0. 59, and in the plasma of the first discharge after a gas change, the wall-released isotope amount to 65% .

结果表明，等离子体在壁处的反射系数约为0.59，变换工作气体后，在第一次放电的等离子体中，由壁释放的同位素含量约占65％。

If we calculate the change in entropy during gas mixing, we will find that this quantity is positive.

如果我们计算气体混合过程中熵的变化，我们会发现这个量是正的。

And so that means that delta u is always calculable from Cv dT for any ideal gas change.

这意味着对理想气体,Δu只需利用Cv，dT计算。

PROFESSOR BAWENDI: So the question was, for an isothermal expansion, delta u does not change, therefore, The answer is that's true only for an ideal gas.

你的问题是，在等温过程中，内能是否，这只对理想气体成立。
