第403行：
第403行： − − P.M.Morse写道，热力学关注的是“热力学平衡状态”。在讨论物体与周围热源之间的热量传递时，他也使用了“热平衡”这个短语，尽管没有明确定义一个特殊的术语“热平衡”。 − − 第412行：
第408行： − − J.R. Waldram写到了“一个明确的热力学状态”。他将一个系统定义为“当其观测量随时间停止变化时”的“热平衡”。但是在这个定义之下不久，他写到一块玻璃还没有达到“完全的热力学平衡状态”。 − − − 第422行：
第413行： − − 考虑到平衡状态，M.Bailyn写道: “每个强度变量都有自己的平衡类型。”然后他定义了热平衡、机械平衡和物质平衡。因此，他写道: “如果所有的强度变量都是一致的，那么热力学平衡就是存在的。”他在这里没有考虑外力场的存在。 − −

P.M. Morse writes that thermodynamics is concerned with "states of thermodynamic equilibrium". He also uses the phrase "thermal equilibrium" while discussing transfer of energy as heat between a body and a heat reservoir in its surroundings, though not explicitly defining a special term 'thermal equilibrium'.

J.R. Waldram writes of "a definite thermodynamic state". He defines the term "thermal equilibrium" for a system "when its observables have ceased to change over time". But shortly below that definition he writes of a piece of glass that has not yet reached its "full thermodynamic equilibrium state".

Considering equilibrium states, M. Bailyn writes: "Each intensive variable has its own type of equilibrium." He then defines thermal equilibrium, mechanical equilibrium, and material equilibrium. Accordingly, he writes: "If all the intensive variables become uniform, thermodynamic equilibrium is said to exist." He is not here considering the presence of an external force field.
