摘　　要：本文研究了22周中的9个强质子耀斑活动区的共同特征,研究结果表明:单个团状结构黑子,即众多异极性黑子本影核紧锁在同一半影结构中的δ型黑子是强质子耀斑活动区的典型形态特征。黑子群的旋转是质子耀斑活动区的又一重要特征,黑子群的旋转方向与日面南、北半球无关。强质子耀斑的爆发总是在黑子群旋转角度达到正或负相极大之后出现。质子耀斑后,磁绳的松弛,黑子群可能会出现反向旋转,强的剪切过程和质子耀斑可能会再度出现。Common characteristics of nine active regions of strong proton flares in 22th solar activity cycle have been studied ;n this paper. The results indicate that 8 type sunspots rvith a single granular structure, that is many umbras with opposite magnetic polarities locked tightly in a single pennumbra are typical morphological characteristics of the active regions of strong proton flares. Another important characteristics of the active regions of proton flares is the rotation of the sunspot groups. The rotative direction of the sunspot groups have no connection with southern and northern hemisphere on solar disk. When rotative angle of the sunspot groups reaches positive or negative maixmum, proton flares will produce in those active regions. After proton flares,due to the slack of the flux rope sunspot groups can rotate in the inverse direction, and strong magnetic shear configurations and proton flares occur once again.
