| 摘 要： | 1980年2月16日日全食期间,在云南瑞丽进行了地磁场的正常与快速两种记录,分析了地磁日变化、小扰动和地磁脉动的变化。结果表明:磁偏角偏东（-0.8′±0.2′）,水平强度有微小的变化（-2.9γ±1.6γ）;地磁小扰动的幅比减小;这与电离层E层的电子密度的变化相对应。

| Abstract: | Three-component （H. D. Z.） normal and quick run （H. D.） records of the earth's magnetic field were made at Ruili, Yunnan Province during Feb. 16, 1980, total solar eclipse. Daily variation, small disturbance and magnetic pulsation were analysed. There was a change of - 0.8' ± 0.2" in D and - 2.9 ± 1.6γ in H. The amplitude ratio of small disturbances was decreased. These changes are consistent with the change in electron density in the E layer during the eclipse. |
