摘　　要：根据相对论力学对带电粒子束在其自生场作用下通过外层空间的真空中传输时束的扩散进行了研究。提出了一种计算粒子束径向半径扩散的方法 ;计算并讨论了粒子束类型、能量、流强和出口初始半径等各种因素对束扩散的影响 ;得出了尽可能减少粒子束扩散的束参数。所得结果同现有公布的数据相符合。The Relativity Theory has been used to study the spreading of charged particle beams propagating in the vacuum of outer space because of its self generated field,a method calculating beam spreading radius in radical spreading of particle beams is presented.We calculate and discuss the relations between the beam spreading radius and the factors influencing the propagation of particle beams,such as beam type,beam energy,current intensity,initial radius etc.And we obtain that the beam parameters can be used to reduce the beam spread as far as posible.The calculated results are in agreement with open data now.
