摘　　要：质子耀斑活动区再现规律的研究结果表明，日面上存在着经度方向漂移式的“活火山”，即质子活动复活体．“活火山”定期地复活，并爆发质子耀斑．其复活长周期为８—１１．６年，与活动周１１年周期基本一致；短周期为１—２．６年，与活动周峰年时间宽度一致．在２２周峰年中，日面南北半球上各有一个强质子活动复活体，它们爆发峰值流量≥１００ｐｆｕ和≥１０００Ｐｆｕ的质子耀斑各占周期同类耀斑总数的７０．７％和８３．３％．Recurrent law of the active regions for proton flares are studied in this paper. The results indicate that on the sun there are 'active volcanos' of the motion along longitude, that is active reviviscent bodies of the proton flares. In 22th solar activity cycle, there are two stronger active reviviscent edes of the proton flares on the sun, they are in two latitude bands of 26°- 35°N and 20°30°S. The proton flares with peak fluses≥100pfu and ≥1000pfu produced by these reviviscent bodies are about 70.7% and 83.3% of those on the solar disk. Long periods of the revivifications for active reviviscent bodies are about 8- 11.6 years, short periods are 1-2.6 years. Due to long and short periods of the revivification for the reviviscent bodies consist with 11 years periods of the solar activity cycle and time interval of the peak years, therefore, the periodic revivifications of the active reviviscent bodies can be important cause of the 11 years periodic variation of the solar activity cycle and intensive eruptions of the flares during solar active maximum.
