摘　　要：People have long begun considering the relativity of the atmospheric radioactivity with the sun activity and the atmospheric conditions.An annular eclipse of the sun took place in China on the 23rd September, 1987. On this occasion, we performed an experimental observation of the γ-rays from 100 keV to 830 keV in atmosphere at sea level at Tianchang County in Anhui Province which is located at the southern edge of the annular eclipse band, i. e. at longitude 119°01′E, latitude 30°41′N, at an altitude of 20.8 m. The exact time of the annulr eclipse of the

关 键 词：annular eclipse of the sun RADIOACTIVITY in atmosphere.
