In this paper, the magnetie field of the active region corresponding to the flare with the continuum emission, which erupted on July 5, 1989, is analysed. The results show that the magnetic intensity is stronger and the sunspot area is larger when the preceding sunspot appears, and the former is weaker and the latter is smaller when the following sunspot occurs. The neutral line between the two regions with opposite magnetic polarities is like the "V" letter in shape, three of the four flare cores are situated...

In this paper, the magnetie field of the active region corresponding to the flare with the continuum emission, which erupted on July 5, 1989, is analysed. The results show that the magnetic intensity is stronger and the sunspot area is larger when the preceding sunspot appears, and the former is weaker and the latter is smaller when the following sunspot occurs. The neutral line between the two regions with opposite magnetic polarities is like the "V" letter in shape, three of the four flare cores are situated on either side of the neutral line, except that the other one is situated in the quiet background and the flare core with the most obvious continuous emission is situated at the point of intersection between the magnetic shear and extruding lines, where there is the maximum gradient of the magnetic field (0.52GS/km).

The diagenetic chemical processes of Iorn,Manganese were studied forcoastal sediment in Xiamen Harbour. We measured the porosity pore water salinity,redox po tential (Ept. )and the vertical distribution of Mn2+ and Fe2+ for the Sediment column in different seasons. The results proclaimed that the chemical diagenesis of Iorm, Manganese were complicated by the uneven distribution and different zores of silt and by the irregular percolating of continental fresh water. Most gradations of sediment column were middle...

The diagenetic chemical processes of Iorn,Manganese were studied forcoastal sediment in Xiamen Harbour. We measured the porosity pore water salinity,redox po tential (Ept. )and the vertical distribution of Mn2+ and Fe2+ for the Sediment column in different seasons. The results proclaimed that the chemical diagenesis of Iorm, Manganese were complicated by the uneven distribution and different zores of silt and by the irregular percolating of continental fresh water. Most gradations of sediment column were middle reducibili-ty. The maximum value appeared and did not change with seasons for pore water Mn2+ in the 0-2 em layer(Ept degrease with Maximum gradient). Mn2+degrease extensively with depth below 2 cm layer. Pore water Fe2+ and Mn2+ changes with the similar tendency. Increasing reducibility in sediment column,MnO2 was reduced first than Fe2O3. The sequence was consistent with that of Gibbs' free energy degreasing.
