摘要：
<正> The second law of thermodynamics has been proven by many facts in classical world.Is there any newproperty of it in quantum world?In this paper,we calculate the change of entropy in T.D.Kieu's model for quantumheat engine(QHE)and prove the broad validity of the second law of thermodynamics.It is shown that the entropy ofthe quantum heat engine neither decreases in a whole cycle,nor decreases in either stage of the cycle.The second lawof thermodynamics still holds in this QHE model.Moreover,although the modified quantum heat engine is capable ofextracting more work,its efficiency does not improve at all.It is neither beyond the efficiency of T.D.Kieu's initialmodel,nor greater than the reversible Carnot efficiency.
