Ⅲ型爆发的初始源研究

Study of Primary Type Ⅲ Burst Sources

本文使用法国Nancay MarkⅢ太阳射电日像仪1980—1981年观测资料,在169MHz上分解出9个Ⅲ型爆发的初始源。其时间分辨率为0.04秒。东西向空间分辨率为1.’2,南北向为2.’7到4.’3之间。初始源的特征是无结构源。

Two dimensional observations of Nine primary type Ⅲ burst sources obtained at 169 MHz with the Mark Ⅲ Nancay Radioheliograph are presented. The resolution of time is 0.04 second. In the E. W. direction, the half power resolution is 1.2' . In the N. S. branch is comprised between 2.7' and 4.3'. The primary type Ⅲ burst sources are structureless sources.
