| 摘 要： | 文章从理论推导与实际应用两方面探讨了热力学教材中存在的问题,认为国内外多种教材在非稳定流动过程能量平衡方程的推导中只考虑了物质流的非稳定性,疏忽了与物质流密不可分的状态参数、运动参数、位置参数的非稳定性.

| Abstract: | The discussion about theoretic deduction and actual application in teaching material of thermodynamics was investigated in the present paper.The results indicate that there are many faults in the books in homeland and overseas in deducing the energy balance equation of nonsteady-state fluid process such as considering merely non-stability of mass-flow.Actually,the parameters concerning of state,momentum and position are also indispensable to the mass flow process.The conclusion is significant to the course of thermodynamics in higher education. |
