Besides, the explanations on the deciding of spontaneous process are unclear.
自发过程是化学热力学一个极为重要的基本概念,但是各教材对其定义历来不尽一致,对自发过程判据的阐述也不十分清楚,给教学带来了一定困难。
This paper shows the faults of existing definiton of spontaneous process, suggests a scientific and rational definition of spontaneors process, specifies it's advantages and uses it to answer some puzzling questions.
指出了现有的几种自发过程定义的不足之处,提出了一种较科学、较合理的自发过程定义,阐述了它的优点并用它来解答一些疑难问题。
This paper has analyzed several basic problems in the engineering thermodynamics course especially,including the conception of “spontaneous course”、“balanceable state”,and the issue of temperature summing、single heat reservoir thermodynamic cycle.
本文重点分析了工程热力学课程中的几个基本问题,包括“自发过程”的概念、“平衡状态”的概念,以及温度的相加计算问题、单一热源的热力循环等,对这些概念的本质进行了深入阐述。
