摘要：
Based on the law of increase of entropy, non-equilibrium coefficients are defined for scaling the departure from local thermodynamic equilibrium (LTE) of non-LTE plasmas. Numerical examples show that the proposed non-equilibrium coefficients are correct in trend and evaluate the departure quite accurately. Using these coefficients, accurate criteria for full LTE can also be obtained. (C) 2002 Elsevier Science Ltd. All rights reserved.
