摘　　要：本文从热力学第二定律的克劳修斯说法出发,并结合开尔文说法,推出了克劳修斯不等式.本文还得到了∮δQr/θ=0的充要条件(θ为温标未定时的温度,Qr为可逆热),并由此自然地引出了熵函数及热力学温标.This paper deduces the inequality of Clousius from the Clousius and Kelvin statements of the Second Law of Thermodynamics. The paper also obtains the necessary and sufficient condition of ∮δQr/θ= 0 ,where θ is temperature whose scale is not defined and Qr heat during reversible process. Entropy and thermodynamic temperature scale are obtained naturally based on above condition.

关 键 词：热力学 熵 热力学温标
