摘要
1990年7月30日观测到一个射电大爆发,其中在2840MHz射电爆发的峰值附近,发现了周期约为30ms的快速脉动现象,脉动是窄带的,调制度约为50%。
お? An outstanding solar radio burst was recorded on July 30, 1990. In this burst, fast pulsations with periods of about 30 ms were found at the maximum of the radio burst at 2840 MHz. The pulsations exhibited narrow bandwidth, and their relative amplitudes were about 50%. Some analyses and discussions of the fast pulsations are presented in this paper.
