摘要: 对热学中的4类泻流问题进行了详细的计算,并对结果进行了分析讨论.恒温的泻流问题有解析的解,而绝热泻流问题往往受限于数学知识只能得到数值的结果;同时本文也对泻流的近平衡态条件进行了大致的分析.这些将有助于广大师生对于泻流问题的全面认识.

关键词: 泻流, 恒温容器, 绝热容器, 分子数密度, 平衡态

Abstract: Four kinds of effusion problems in thermal physics is calculated in detail and the results are discussed.The problems for constant temperature effusion have analytlcal solutions,but the adiabatic effusion problems often have only numerical results due to limited mathematics knowledge.The conditions of quasi-equilibrium state in effusion process are also analyzed generally.They will help teachers and students get entire understanding of the effusion problems.

Key words: effusion, constant temperature container, adiabatic container, density of molecular number, equilibrium state
