摘　　要：随着人类太空发射活动的日益增长,在轨的空间目标越来越多,这些空间目标不可避免地发生爆炸解体、碰撞解体等解体事件,而解体事件将产生大量空间碎片形成碎片云。文章针对空间目标解体产生的大量碎片云的轨道寿命分布问题进行探索,这是首次面向解体碎片云的轨道寿命的研究,研究结果表明,在近地轨道上的空间目标解体产生的碎片云中也可能存在大量碎片的轨道寿命超过25年。文章研究结果对太空交通管理、太空交通事故应对处置、雷达空间碎片探测、太空态势感知等均具有参考价值。With the increasing human space launch activities,there are more and more space targets in orbit.These space targets inevitably undergo disintegration events such as explosion and collision,and disintegration events will generate a large amount of space debris to form debris clouds.This article explores the orbital lifetime distribution of a large number of debris clouds generated by the disintegration of space targets.This is the first international study on the orbital lifetime of disintegrated debris clouds.The research results indicate that a large number of debris with orbital lifetimes exceeding 25 years may also exist in the debris clouds generated by the disintegration of space targets in near earth orbit.The research results of this article have reference value for space traffic management,response and disposal of space traffic accidents,radar space debris detection,and space situational awareness.
