热力学第零定律
热力学第零定律，又称热平衡定律，是一个关于互相接触的物体在热平衡时的描述，以及为温度提供理论基础。最常用的定律表述是：
“
若两个热力学系统均与第三个系统处于热平衡状态，此两个系统也必互相处于热平衡。
”
换句话说，第零定律是指：在一个数学二元关系之中，热平衡是递移的。

Zeroth law of thermodynamics 热力学第零定律The zeroth law of thermodynamics states that if two thermodynamic systems are each in thermal equilibrium with a third, then they are in thermal equilibrium with each other. Two systems are said to be in the relation of thermal equilibrium if they are linked by a wall permeable only to heat and they do not change over time. As a convenience of language, systems are sometimes also said to be in a relation of thermal equilibrium if they are not linked so as to be able to transfer heat to each other, but would not do so if they were connected by a wall permeable only to heat. Thermal equilibrium between two systems is a transitive relation. |
