| 摘 要： | 本文研究了一个无自旋的粒子能柱对称引力场中的运动方程．特别地，分别计算了粒子的动能和角动量．结果表明：（ｌ）如果粒子沿弦方向的初速度不为零，则弦的辐射性质使得粒子在此方向的动能总是增加的；（２）粒子绕弦运动的角动量也总是随时间增加的．这为星系旋转的起源提供了一种可能的解释．

| Abstract: | In this paper,the motion equation of a spinless particle in the gravitational field of radiating cosmic string. has been discussed.specially,We have calculated the moinentum and the angular momentum of the particle. Our result shows:(l)If there is initial veloeity along the string,the radiation will make the momentum in this direction increase,(2)If there is initial angular momentum around the string, the angular monentum will be developed afterwards.This provides a possible explanation for the origin of galaxies. |
