摘　　要：研究了太阳宇宙线在日冕区的横向传播特性，提出了具有扩散和逃逸过程的日冕分布粒子源，求出了含有该粒子源的行星际传输有源方程的解，并利用IMP-8，Helios-1和Helios-2观测到的同一事件不同空间位置的耀斑粒子资料对模型作了检验．A particle distribution due to coronal transport is presented based on maincharacteristics of solar flare particle transport in the corona. The Green function of theinterplanetary propagation equation with the source of the distribution is solved andthe solutions of high energy particle propagation in an infinite medium are obtainedby using the Green funtion. The intensity-time profiles given by numericalcalculations of the theory are compared with the observations for the event 23September 1973 from IMP-8, Hellos--1 and Hellos--2. The results show a goodagreement between theory and observations.
