In this paper, the change of entropy function ( S) in the process of gas throttling expansion has been explored. It has been pointed out that the entropy change associated with the throttling expansions of any gases is al-ways positive, and that the process is irreversible. The total thermodynamic characteristics of throttling expansions have been systematically discussed and summarized. The content involved is of importance in the teaching practice for students to gain better insights into the characteristics of the irreversible process, the function of entropy and the prin-ciple of entropy increase, as well as the relationships among all thermodynamic functions.
