摘　　要：热力学第二定律说明了热力过程进行的方向、限度和条件,是热力学的重要组成部分。本文阐述了热力学第二定律中两种最经典的说法——克劳修斯说法和开尔文说法,为方便学生理解,采用工程和生活中的实际例子对其进行解释,最后对“若违反克劳修斯说法,则总效果必然违反开尔文说法”以及“若违反开尔文说法,则总效果必然违反克劳修斯说法”的两个结论进行了详细的推导证明。The second law of thermodynamics, which describes the direction, limits, and conditions under which a thermodynamic process takes place, is an important part of thermodynamics. Two of the most classical versions of the second law of thermodynamics, Rudolf Clausius and Kelvin, were explained by practical examples from engineering and life for the convenience of students, the conclusion that “if we violate Rudolf Clausius’ s theory, the total effect must violate Kelvin’s theory” and “if we violate Kelvin’s theory, the total effect must violate Rudolf Clausius’ s theory” were proved in detail.
