在1978年9月至1983年12月期间，已经确定了67个太阳粒子事件，这些事件的仪器探测到了3 MeV以上的电子，并且有软X射线观测。根据它们在软X射线中的特征，将这些事件分为脉冲事件和长持续时间事件两类，并发现它们具有不同的性质。起源于脉冲耀斑的事件与强烈的米波长III型爆发和相关的V型连续相关联。与长持续时间耀斑相关的事件可以起源于太阳盘上的任何地方，延伸到更高的质子能量，并且与日冕和行星际冲击密切相关;对于大约一半的长持续时间事件，相关的米波长事件不包括III型爆发。推广了Evenson等（1984）和Kahler等（1984）的结果。
For the period 1978 September to 1983 December, 67 solar particle events have been identified for which the instruments detected electrons above 3 MeV and for which there are soft X-ray observations. The events are divided into two classes impulsive and long-duration - based on their signature in soft X-rays, and it is found that they have different properties. The events originating with impulsive flares are associated with intensed meter-wavelength type III bursts with associated type V continuum. The events associated with long-duration flares can originate anywhere on the solar disk, extend to much higher proton energies, and are well associated with coronal and interplanetary shocks; for about half of the long-duration events, the associated meter-wavelength events do not include type III bursts. The results discovered by Evenson et al. (1984) and by Kahler et al. (1984) are extended.
