Scientific paper

Using isogaussgrams of five days, it is found that the arrangement of the reversed magnetic polarity and the neutral line of the longitude field become twisted during energetic proton flare explosions. It is noted that after that occurrence of the flares, either the arrangement of magnetic polarity or the neutral line of the longitude field tends to a relatively stable state. Most of the bright flare knots of the active region are found to be far away from the neutral line region. The bright knots near the neutral line may be roughly divided into two areas. One is the region with large magnetic field gradient and countercurrent density on both sides of the neutral line; the other is near the 'neutral points' of the field.
