This text according to thermodynamics the second laws,didn t press general textbook to pass the teaching mode of the card promise axioms derivation function circularly from the card promise,but direct from can go against circulation with can t go against the circulating derivation Entropy function,make the student comprehend thermodynamics from a new angle the second laws.

根据热力学第二定律,没有按一般教科书从卡诺循环通过卡诺定理引出熵函数,而是采用直接从可逆循环和不可逆循环引出熵函数的教学模式,从而使学生从一个新的角度去理解热力学第二定律。
