摘要
利用本征值和本征矢量的分析方法,对钠层的光化学反应的寿命进行了研究,结果表明,利用该方法计算出的钠原子的化学寿命与传统理论有所不同.从而证明了在中层顶区,钠层的中上部的扰动主要受大气动力学过程的影响,钠层底部主要由光化学控制.这为利用钠层作为示踪剂研究中层顶大气动力学的理论提供了理论依据.
Using the method of the eignvalue and eignvector analysis of chemical system to study the chemical lifetime of sodium layer. The results show that the chemical lifetime of sodium layer calculated in this paper is very different with the traditionally defined chemical lifetime. The results indicate that in the region near the peak of sodium layer, the dynamical transportation predominant than the photochemical process. But in the region of the bottom side of sodium layer, the photochemistry is the main process. The Na layer can be regarded as a tracer of dynamical perturbation. The results of this paper provide a theoretical basis for analyzing the Lidar observations of sodium layer.
