摘要：
The X-ray background flux (XBF) based on GOES 1-8 Angstrom measurements for the period 1975-2000 is studied. We come to the conclusion that in the XBF the flare contribution is not eliminated but the XBF is dominated by flare and post-flare emission of intense events. Furthermore, we suggest that the characteristic lag of the X-ray background flux with regard to Sunspot Numbers reported for cycle 21 is a secondary effect related to the substantial contribution of large flares to the XBF.
