• 摘要：本文提出监测大气污染的新的大气混浊度指标,大气混浊系数H₂。当大气光学质量数等于2时,它是理想大气透明系数qb₂与实际大气总透明系数P₂之差,即: H₂=qb₂-P₂ 大气混浊系数H₂是一种明确而简单的指标。利用它,我们能确定大气污染的程度;估计由于大气污染削弱的太阳辐射;研究大气污染的分布与变化。在拟定保护大气环境计划方面,它有重要作用。

• Abstract：A new turbidity index of atmosphere, the turbidity cofficient of atmospheric H₂ has been introduced for characterization, of air pollution. It is the difference between transparence coefficient of ideal atmosphere qb₂ and integral transparence coefficient of real atmosphere P₂. If the optical air mass m equals two, thenTurbidity coefficient of atmospheric H₂ is definite and simple as an index which can be used to define intensity of air pollution, estimate extinction of solar radiation for air pollution, study distribution and changes in air pollution. It can also play an important part in planning environmental Protection project in connexion with atmosphere.
