摘要
在分析了近年来对太阳射电爆发与高能质子观测的基础上指出，既非II型也非米波IV型而是强微波爆发几乎总是同高能质子共生的；这一结果否定了以前长期所持的观点。同高能质子共生的微波爆发可分成两类：强脉冲型和强微波IV型，前者共生的被俘质子或相互作用质子要多于逃逸质子，后者则常共生有更多的逃逸质子．作者对每种情况中质子的有效加速过程进行了考虑，并对强微波爆发为何几乎总是有高能质子共生的缘由作了解释．
Based on the data analysis of recent observations of solar radio bursts and energetic protons,it is shown in this paper that neither type Ⅱ nor meterwave type Ⅳ but intense microwavebursts are nearly always associated with energetic protons. This result is contrary to theprevious long-held views. The microwave bursts associated with energetic protons may bedevided into two classes; intense impulsive and type Ⅳ bursts. The former is associated withmore trapped or interacting protons than the escaping ones, and the latter is often associatedwith more escaping protons. Furthermore, the authors considered the efficient acceleration process of protons in each case and explained why the intense microwave bursts are almost alwaysassociated with energetic protons.
