摘要
太阳黑子数是描述太阳活动水平的主要指标,太阳活动直接影响人类健康和人类赖以生存的环境—地球;依据数字信号处理原理,采用多种处理方法,分析处理了1770-1869年的太阳黑子数年均值;得出了太阳黑子存在11-12年周期的结论.结果表明该方法对研究太阳活动规律乃至天体规律是有效的.
The sunspot numbers is the major targets which describes the solar activity level, The solar activity influences human＇s health and human to rely for existence directly of environment-the Eatrth. According to digital signal processing,According to digital signal processing principle and adopting various processing methods, the analysis handled mean of year of the sunspot in 1770- 1869 years, reached the conclusion on sunspot to existll-12 year of the period. The experiments show that method to is effective studying the solar activity regulation and celestial regulation
