| 摘 要： | 作者应用Dobson臭氧光电分光光度计进行低太阳观测时,发现直射光路上总光强比值随太阳天顶角的变化发生两个逆转。随着臭氧总量的增大或者波长的減小,逆转点的天顶角变小。作者同时考虑直射太阳光和散射光,定性地解释逆转原因及其随波长、臭氧总量的变化。

| Abstract: | Using the Dobson's ozone spectrometer, the author discovered that the ratio of the light intensity received on the ground from the direction of sunlight has two reversions when the zenith angle of the sun is very large and there are certain relations between these reversions and the wave-length or total ozone amount. Considering only the absorption of ozone and the scattering of the air, the author attempts to explain these phenomena. |
