With x - ray " s erupting generated by solar proton flare , x - ray transmit toward earth with light speed and isn " t effected by magnetic field of earth . it arrive in earth earlier several decades minutes to hours than proton liquid . make use of the difference of time they spend on space spread , we make alarm for solar proton event by physical character of solar x - ray , which is a very valid means 伴随太阳质子耀斑产生的x射线爆发,它以光速向地球传播而且不受地磁场的影响,它比质子流超前几十分钟甚至几十小时到达地球,利用二者在空间传播的时间差,以太阳x射线某些物理特征警报太阳质子事件是一种十分有效的手段。
At present we have made great efforts on radiation statistics of proton - flare " s x - ray , especially hard x - ray , and character of hard x - ray in the process of proton accelerating , and we have gotten solar x - ray " s character before proton event and bring forward forecasting method which is actualized and proved in fy - 2 satellite " s alarming system of proton event 目前我们已经在质子加速过程中的硬x射线特征、质子耀斑x射线辐射统计(特别是硬x射线特征)等方面作了系统的工作,已获得质子事件前兆的太阳x射线特征,并提出了预报方法,已在fy - 2卫星质子报警系统中加以了实施和验证。
Space environment threaten orbited spacecraft " s safe functioning and astronaut " s health , influence greatly communication depended on based - space way , airmanship orientation , military detection , aim identification , weather observation and source exploration and so on by all sorts of function ( magnetic storm , solar proton event and so on ) 空间环境通过各种效应(如磁暴、太阳质子事件等)对在轨航天器的安全运行及航天员的健康构成了严重的威胁,对依赖于天基手段的通信、导航定位、军事侦察、目标识别、气象观测、资源勘探等等均有重要影响。
