摘　　要：计算了重力波过程对光化加热的影响，并研究了不同温度背景以及不同氧原子的背景分布对该过程的影响．计算表明重力波可以造成中层顶区光化反应加热的损失．随着背景温度的下降以及氧原子密度背景分布的增加，重力波造成的光化反应加热的损失以及它与背景加热率之比也随之加大．In this paper, the effect of gravity waves on the photochemical heating rate is studied. Calculation indicates that gravity waves can cause the loss of photochemical heating rate in mesopause. The influences of different background temperature profiles and atomic oxygen distribution on this process are also studied. The study indicates that as the decrease of background temperature and increase of the background distribution of atomic oxygen, the photochemical heating rate loss caused by gravity waves increase obviously.
