In this paper, the efficiency of carnot cycle in quasi-steady process is calculated when several especial real gas and discretional real gas were regarded as work substance.

先以几种特殊的实际气体为工作物质，计算准静态卡诺循环的效率，然后再推广到任意的实际气体。

And a numerical method with high resolution TVD schemes for solving the governing equations of real gas flows is developed.

以此为基础，构造了求解真实气体流动控制方程的高分辨率TVD数值格式。

This paper discusses the seepage equations of the real gas in mines by means of the theory of infiltration and thermodynamics .

利用渗流力学理论和热力学理论，本文提出了矿井煤层真实瓦斯气体的渗流方程，并对该方程进行了讨论。
