【摘要】 本文从微观角度分析了几个典型的功变热过程，根据其共性引入了一个功变热过程简化模型，采用微正则分布，计算功变热过程的熵变。结果表明，在功变热过程中，系统的熵增加，且熵在任何惯性参照系中表达式是一致的。更多还原

【Abstract】 In this paper, we analysised several topical processes of work into heat. According to their same character, we introduced a simple model of work into heat, and calculated entropy change of the process by micrdocanonical ditribution As result of, the entropy is increased in the process, and the result is the same in any inertial reference frame.更多还原
