摘要

太阳光产生的电离层D区对中频波的传播影响很大。为了研究日全食对D区的响应，我们对日本日环食和日偏食两个相似时段的中频广播波强度进行了观测。因此，虽然日偏食比日环食有更多的阳光，但在日偏食期间观测到更多的中频广播。

Observation of the MF Broadcasting Wave Intensities on the Solar Eclipse

The ionospheric D region generated by sunlight has great influence on the MF wave propagation. To investigate the response on the D region during the solar eclipse, we observed the MF broadcast wave intensities for two similar periods, the annular and the partial solar eclipse in Japan. As a result, more MF broadcasts were observed during the partial solar eclipse although the partial solar eclipse had more sunlight than the annular solar eclipse.
