摘　　要：航天器在太空中运行,将不可避免地受到空间天气的影响,而太阳爆发性活动是引发空间天气变化的源头。从2008年10月起,太阳开始进入第24太阳活动周,预计于2013—2014年到达太阳活动峰年,伴随着太阳活动水平会明显加强,存在发生强空间天气事件的可能性。从航天器工程的角度,介绍了太阳活动的基本规律,分析了太阳活动峰年期间的空间环境基本特征,并阐述了空间天气事件对航天器产生影响的机理与过程,以期对即将到来的第24太阳活动周峰年对航天器可能产生的影响有一个较为全面和客观的认识。The spacecraft orbiting in space will be affected by space weather inevitably,while the solar explosive event is the source of space weather variations.From October 2008 on,the sun enters solar cycle 24.It is predicted that the solar maximum will arrive in 2013—2014,while the solar activity will be enhanced significantly and severe space weather events may occur.In view of spacecraft engineering,this paper introduces the common principle of the solar activity and the basic characteristics of space environment during the solar maximum,and then describes the mechanism and process of space weather events having an effect on the spacecraft,in order to comprehensively and objectively understand the possible influence of the upcoming 24th solar maximum on the spacecraft.
