| 摘 要： | 文章评价了颗粒大于1cm的碎片模型,它包含大于10cm的一组粒子和介于1～10cm之间的粒子,它们是由空间暴露模拟得到的。接着讨论了尺寸范围介于0.1～10mm之间的小粒子束流。假定这些粒子主要是由小粒子与卫星碰撞产生的。这种碰撞主要发生在450～500kin的高度范围内(空间站高度),碰撞与否还取决于轨道高度和离心率。

| Abstract: | The past debris model of particles larger than 1 cm is briefly reviewed.The objects in this model are composed from two classes:the cataloged objects larger than 10 cm,and objects between 1 cm and 10 cm,obtained form the simulation of explosions in space.Subsequently the problem of modelling the flux of small panicles in the size range between 0.1 mm and 10 mm is discussed.It is supposed that those particles are mainly generated by collisions between a small particle and satellite.This collision generated on the altitude range 450 to 500 km(space station altitude)is shown to be extremely dependent on the altitude and eccentricity of the orbit in which the collision occurred. |
