一维等熵不定型流问题

On the Issue of Indeterminate Hydrofield of One-dimension Equal Entropy

把动力学规律中的质量守恒表现为连续方程 ,把牛顿第二定律表现为气体流动的欧拉方程 ;把热力学第一定律表现为能量守恒方程 ;把与气体压缩性有关的状态变化规律表现为状态方程。通过建立这四个方程 。

On thin paper ,energy conservation in dynamico could be expressed as equations of continuity ,and Newton's second law as Euler's equation ,the first law of thermodynamico as the energy conseriation equation ,state variety about gas compressi-bility as state equaion,As soon as above four equations are setup,the variational law of the four parameters in the indeterminate hyarofilld could be certified.
