The relativity of negative absolute temperature system

Abstract:

The paper draws the concept of negative absoute temperature form thermodynamic system,studies the reationship between energy,absolute temperature and entropy in accordance with operating principle of laser and on the basis of which,the relativity of negative absoleete temperature is discussed.

Key words: laser energy entropy negative absolute temperature
