中文摘要:

用从 1976 ~ 2006 的全部的太阳的发光(TSI ) 的观察数据,在 TSI 和太阳黑子数字(SSN ) 之间的全部的太阳的发光和关系的进化与小浪技术被分析了。连续小浪变换(享特威) 的结果显示 TSI 有多尺度的进化特征。在低频率乐队, TSI 和 SSN 从 8 ~ 11.4 与一个重要、稳定的摆动时期显示出类似的变化一。当仅仅在太阳的周期的最大的时间附近,在高频率乐队 TSI 和 SSN 从 2 ~ 6 个月介绍一个重要断断续续的摆动时期时。生气小浪变换的结果显示在 811.4 一乐队在 TSI 和 SSN 之间有重要同相的回声摆动,在 SSN 的变化是在 TSI 的前的 2 个月的地方。那些结果在 811.4 的时间规模为 TSI 周期的变化作为主要原因证实 SSN 一。然而,为 26 月乐队,,重要回声频率仅仅在太阳的周期,而是在 TSI 之间的阶段关系的最大的时间以内被观察, SSN 是不稳定的。最后,从 1878 ~ 1975 的一个可靠 TSI 每月的系列被重建并且测试。

英文摘要:

Using the observational data of total solar irradiance (TSI) from 1976 to 2006, the evolution of total solar irradiance and the rela- tionship between TSI and sunspot number (SSN) have been analyzed with the wavelet technique. The results of the continuous wavelet transform (CWT) indicate that the TSI has multi-scale evolutionary characteristics. In the low frequency band, the TSI and SSN show similar variation with a significant and steady oscillation period from 8 to 11.4 a. While in the high frequency band, only around the maximum time of solar cycles, both the TSI and SSN present a significant intermittent oscillation period from 2 to 6 months. The results of the cross wavelet transform indicate that there is significant in-phase resonance oscillation between the TSI and SSN in 8-11.4 a band, where the variation of the SSN is 2 months ahead of that of TSI. Those results confirm the SSN as the primary cause for TSI's periodic variation in the time scale of 8-11.4 a. However for the 2-6 month band, significant reso- nance periodicity is observed only within the maximum time of solar cycle, but the phase relationship between the TSI and SSN is unsteady. Finally, a reliable TSI monthly series from 1878 to 1975 is reconstructed and tested.
