Several linear regression equations of the specific heat at constant volume for ideal gas based on MATLAB were proposed and proved by mathematical statistics, with maximum relative error less than 5%.

利用MATLAB的数值回归分析功能，得到了几种常见理想气体定容比热容与温度的线性回归公式，数理统计分析的结果证明了这些回归公式的合理性，回归公式的最大相对误差低于5%。

And we saw that, you saw that the Joule coefficient for an ideal gas was zero.

我们会发现，你们也会发现，理想气体的焦耳系数是零。

youdao

For the ideal gas it's this.

对理想气体就是这个。

youdao

All right, so gamma is for ideal gas, 1 is bigger than one.

对理想气体，γ大于。

OK, this is only true for an ideal gas, and we went through that mathematically where the, with a chain rule.

这一关系只对理想气体成立，上节课我们,用链式法则推导出了这一关系。
