Description: 太阳黑子是人们最早发现也是人们最熟悉的一种太阳表面活动。因为太阳内部磁场发生变化，太阳黑子的数量并不是固定的，它会随着时间的变化而上下波动，每隔一定时间会达到一个最高点，这段时间就被称之为一个太阳黑子周期。太阳黑子的活动呈现周期性变化是由施瓦贝首次发现的。沃尔夫 (R.Wolfer)继而推算出11年的周期规律。实际上，太阳黑子的活动不仅呈11年的周期变化，还有海耳在研究太阳黑子磁场分布时发现的22年周期；格莱斯堡等人发现的80年周期以及蒙德极小期等。由于太阳黑子的活动规律极其复杂，时至今日科学家们仍在努力研究其内在的规律和特性。事实上，对太阳黑子活动规律的研究不仅具有理论意义，而且具有直接的应用需求。太阳黑子的活动呈现周期性变化的，沃尔夫(R.Wolfer)根据在过去的288 年(1700年~1987 年)间每年太阳黑子出现的数量和大小的观测数据推算出11 年的周期规律。我们利用Matlab强大的数据处理与仿真功能，对Wolfer数进行功率谱密度分析从而可以得到对太阳黑子活动周期的结论。-It is the first discovered sunspots is the most familiar kind of solar surface activity. Because the magnetic field inside the sun changes, the number of sunspots is not fixed, it changes over time fluctuations, the time intervals to reach a high point, this time it was called a sunspot cycle. Cyclical changes in sunspot activity first discovered by Schwabe. Wolf (R. Wolfer) and then calculate the 11-year cycle rule. In fact, sunspot activity was not only the 11-year cycle, as well as sea-ear magnetic field distribution in the study of sunspots and found a 22-year cycle Grameen Myers, who found 80-year cycle and the Maunder minimum, etc. . Because the law is extremely complex sunspot activity, scientists are still working today to study its internal rules and features. In fact, the laws of sunspot activity on the study not only of theoretical significance, but also has direct application requirements. Cyclical changes in sunspot activity, and Wolf (R. Wolfer) based in the past 288 yea

Description: 太阳黑子是人类长久以来感兴趣的问题。此处运用matlab代码对太阳黑子的记录的数据进行处理，希望能提供帮助- Using archival records,astronomers have applied Wolfer s rule to determine sunspot activity back to the year 1700. Today the sunspot index is measured by many astronomers and the worldwide distribution of the data is coordinated by the Solar Influences Data Center at the Royal Observatory of Belgium.
The text file sunspot.dat in the matlab/demos directory has two columns of numbers. The first column is the years from 1700 to 1987 and the second column is the average Wolfer sunspot number for each year.
