补充资料:热力学:热力学第零定律
热力学第零定律:
热力学中以热平衡概念为基础对温度作出定义的定律。通常表述为﹕与第三个系统处於热平衡状态的两个系统之间﹐必定处於热平衡状态。图中A 热力学第零定律示意图 ﹑B 热力学第零定律示意图 ﹑C 热力学第零定律示意图 为 3个质量和组成固定﹐且与外界完全隔绝的热力系统。将其中的B ﹑C 用绝热壁隔开﹐同时使它们分别与A 发生热接触。待A 与B 和A 与C 都达到热平衡时﹐再使B 与C 发生热接触。这时B 和C 的热力状态不再变化﹐这表明它们之间在热性质方面也已达到平衡。第零定律表明﹐一切互为热平衡的系统具有一个数值上相等的共同的宏观性质──温度。温度计所以能够测定物体温度正是依据这个原理。
