| 摘 要： | 本文利用HEAO-1A2的2-60keV弥漫X射线资料,扣除了银河系起源的X弥漫背景影响,得到有关宇宙X背景的资料.在宇宙X背景的各向异性是由Compton-Getting效应引起的假设下,导出其各向异性度δ=(0.45±0.18)%,从而得到太阳系相对于2-60keV宇宙X背景“海”的运动速度V=(397±159)km/s.这个值与由微波背景观测资料得到的结论不矛盾.

| Abstract: | Using the new data of the 2-60 keVdiffuse X-ray background from HEAO-1 A2 and subtracting the model galactic X-ray component, the cosmic X-ray background data have been obtained.Considering the anisotropy caused by the Compoton-Getting effect, we derived d= (0.45±0.18)% and then V= (397 ±159) km/s. Where 6 is the anisotropy and Vis the velocity of the solar system with respect to the diffuse cosmic X-ray sea. There is no inconsistency with the well known anisotropy in the microwave background. |
