利用小波变换研究了太阳活动中施瓦贝循环的性质。我们研究了相对太阳黑子数记录的太阳活动施瓦贝周期的主要范围,发现施瓦贝周期的主要范围是8年到14年的周期跨度。我们对太阳黑子相对数和黑子群数进行了11年相位的比较。结果表明,1710年至1810年期间两个阶段之间存在一定差异,而1810年至1990年期间两个阶段几乎相同。
Properties of the Schwabe cycles in solar activity are investigated by using wavelet transform. We study the main range of the Schwabe cycles of the solar activity recorded by relative sunspot numbers, and find that the main range of the Schwabe cycles is the periodic span from 8-year to 14-year. We make the comparison of 11-year's phase between relative sunspot numbers and sunspot group numbers. The results show that there is some difference between two phases for the interval from 1710 to 1810, while the two phases are almost the same for the interval from 1810 to 1990.
