流星体与空间碎片模型综述

SUMMARY OF METEOROIDS AND SPACE DEBRIS MODEL

空间中存在着大量的流星体和空间碎片,这种数量持续增长的空间物体无疑将对未来太空任务安全带来巨大挑战和负面影响.本文回顾了流星体和空间碎片模型的发展历史,详细阐述了各模型的主要特性与适用范围,重点讲解了碎片从解体事件发生到未来空间碎片总量演变过程中不同模型的合理运用,梳理了空间事件与模型之间的关系,对比了不同模型的优缺点并给出了选用建议,最后对未来我国自有太空体系模型的构建提出了展望.

There are a large number of meteoroids and space debris in space.The growing space objects will undoubtedly bring formidable challenges and negative impacts on the security of future space missions.This article reviews the evolution of meteoroid and space debris models,elaborates on the main characteristics and application scope of each model,and focuses on the rational use of different models from the occurrence of the fragmentation event to the evolution of the total amount of space debris in the future.The paper also studies the relationship between space events and models,compares the advantages and disadvantages of different models,offers scenario-specific suggestions on model selection,and finally envisages China’s own space system model in the future.
