英文摘要：

Based on the observations of 〉0.3 MeV electrons from the polar orbit satellite NOAA/POES during 1996 -2006, the characteristics of 〉0.3 MeV electrons penetrating into the slot region in radiation belt were studied. By comparing the property of high energy electronsr penetration to the interplanetary condition, solar activity and geomagnetic disturbance, it is found that 〉0.3 MeV electron penetration always takes place during magnetic storms. Also, the incidence of electron penetration has a correlation with solar activity cycle. In particular, analysis of the correlation between 〉0.3 MeV electron flux in the slot region and Dst index indicates that we can use Dst index to calculate the electron flux. In that case, we can establish a model to forecast the penetration of 〉0.3 MeV electrons to the slot region in radiation belt.
