| 摘 要： | 本文介绍了1980年2月16日日全食时,在云南鹤庆县（100°12′E,26°35′N）,测量日本ETS-Ⅱ同步卫星136MHz信标法拉弟旋转所得到的一些主要观测结果:（1）电子总含量的日变曲线中出现提前日落现象;（2）F区峰下电离对法拉弟旋转的贡献在日食期间相对变小;（3）没有出现与日食明显有关的声重波扰动。

| Abstract: | In this paper, results of the TEC measurement by 136 MHz beacon of BTS-Ⅱ during the solar eclipse of Feb. 16, 1980 at He-qing station （100°12"E, 26°35'N） are discussed. The eclipse produces a premature sunset without any bite-out on the TEC curve during the course of the eclipse. However, it is indicated by the non-linear relationship between TEC and NB （the underlying electron content below F2-layer peak） that NB makes relatively less contribution to the measured Faraday rotation around the eclipse maximum. These results imply that for a near sunset eclipse, its dynamic effect on the ionosphere is very marked and its photo-chemical effect is restricted in the lower ionosphere. No gravity wave can be associated immediatly with the eclipse, though quasi-periodic disturbances of very small amplitude can be seen on the residual curve of TEC after the running mean has been removed. |
