| 摘 要： | 本文借助于Budden的频高图分析方法,分析了云南省瑞丽县弄岛街1980年2月16日日全食期间的电离层资料,计算了日食日及控制目的剖面,给出了剖面参数,得到了E层临频及最大电子浓度所在高度在日食过程中的变化,也研究了F层的日食效应,指出了在各选定频率上的反射虚高和真高在日食过程中的变化,发现在300公里以下的各给定高度上,尤其是在270公里附近的高度上,其电子浓度明显地下降。

| Abstract: | The ionospheric data during the total eclipse of February 1980 over Ruili in Yunnan （97°36'B, 23°47'N）, are analyzed by use of Budden's method for the calculation of electron density N（h） from hr（f）. The profiles and it's parameters of electron density of the eclipse's day and of the controlling days are estimated. The changes of the critical frequencies and the heights of the maximum density of E and F region were obtained during the eclipse. The reflectiv virtual heights h'（f） and the real heights Z（N） at various selected frequencies were suddenly increaed during the eclipse's process, while the electron density at each chosen height below 300 km, especially at the height of 270 km, decreased considerably. |
