中文摘要采用线性回归的方法研究了太阳活动平静时期空间高能质子和重离子微分通量与地面0ULU宇宙线台站中子强度之间的相关性,利用地面中子强度数据来反演空间高能质子和重离子通量.从质子和重离子的能谱出发,结合OULU台站中子强度的数据,提出了由地面中子强度数据反演空间高能质子和重离子微分通量的新方法.文中以GOES卫星上350-420MeV,420-510MeV,510-700MeV,>700MeV(P8-P11)四能道的高能质子和ACE卫星上的元素C为例,并将反演的数据与测量结果比较,二者符合较好.为了探索这种反演方法在空间辐射环境描述中的应用,同时利用2006年11月和12月质子通量的反演结果对反演方法进行了验证,证明利用这一反演方法可以从地面中子强度的数据很好地反演出空间质子和重离子的微分通量.
英文摘要By using the method of linear regress, the relation between the cosmic ray intensity of the OULU neutron monitor and the differential fluxes of space energetic proton and ion during quiet time has been studied. The differential spectrum of interplanetary particles with high energy is also calculated through the intensity of neutron at the ground level. On the basis of the energy spectra of proton and ion, a new calculation of the differential fluxes of proton and ion with high energy is suggested by combining the intensity of the neutron measured by OULU neutron monitor. For particular discussion, four channels (350420 MeV, 420510 MeV, 510700 MeV, >700 MeV)on the GOES satellite and the element C on the ACE satellite are chosen as examples. Through comparison, it is concluded that the result is well consistent with the measurements. In order to prove the practicability of the method mentioned above in description of the space radiant condition,the differential proton fluxes are calculated during November and December in As a result, it is concluded that the differential fluxes of space proton and ion from the intensity of the ground neutron with this method.2006 by the method.may be well rebuilt
