| Abstract: | Using the work-entropy relation of the heat engine and the concept of availability, the second-law efficiency of the heat engine is given, a new concept-the relative lost of work of a heat engine is introduced, and the degress of irreversibility among several real power sources are compared. |

| Keywords: | heat engine efficiency relative lost of work irreversibility |
