摘要
讨论Ｅｉｎｓｔｅｉｎ参数、谐振子强度、权重跃迁矩的平方、线强及吸收系数等分子光谱多数的定义，导出了它们之间的关系，为计算上层大气辐射提供了物理基础。
ABSTRACT The general definitions of the Einstein transition-probability coefficients the cacillatOr strength，the weighted transition moment squared ,the line intensity and the abeorption coefficient are discussed.The relations among these porameters are derived， This provides a needed niche for upper atmcapheric non-local thermodynamic equilibrium radiative transfer calculations·kev Words：NOn-local thermodynamic equilibrium radiative transfer；Einstein coefficients；Oscillator，strengths； Weighted transition moment squared；Line intensity；Absorption coefficient；Spectropic data.
