【摘要】：太陽活動，指的是包括太陽黑子、太陽耀斑、太陽日珥和日冕物質(zhì)拋射等多種現(xiàn)象的統(tǒng)稱。其中太陽黑子最為引人注目，因而被頻繁研究。其物理形成機制與長期行為特征已取得較大進展。太陽黑子是太陽光球?qū)拥幕顒�，但同時與太陽磁場密切相關(guān)。而作為其他太陽活動同樣與太陽表面磁場有著密切聯(lián)系，，所以與黑子之間的關(guān)系也亟待闡明。太陽暗條作為日冕層活動現(xiàn)象與太陽表面磁場有著重要的關(guān)聯(lián)。所以它作為與黑子不同太陽大氣層與黑子的長期活動的異同令人十分關(guān)心。并且通過闡明異同可以很好的幫助解釋太陽黑子在暗條的形成爆發(fā)中起著什么樣的作用。作為與黑子極為相關(guān)的日冕層活動，許多人認為其同樣具有與黑子相似的非線性性質(zhì)及其周期性。其中黑子的非線性性質(zhì)已有大量的研究涉及，而太陽暗條的研究則鮮有人問津。為此我們希望通過對暗條的非線性性質(zhì)及周期性進行研究，以發(fā)現(xiàn)其中的異同并加以解釋。對此，我們進行了以下工作： 1、對從法國墨東天文臺所觀測到的1919年3月至1989年12月的每卡靈頓自轉(zhuǎn)周太陽暗條數(shù)進行一維到多維的重構(gòu)成。這種相空間重構(gòu)的目的是為了將數(shù)據(jù)內(nèi)部存在的動力學(xué)特征以相軌跡形式展現(xiàn)在高維度的相空間中已掌握其動力學(xué)特征。 2、將該數(shù)據(jù)進行關(guān)聯(lián)維數(shù)的計算，用以分析出其動力學(xué)構(gòu)成的復(fù)雜性和可能構(gòu)成形式。關(guān)聯(lián)維的計算可用于分析描述數(shù)據(jù)產(chǎn)生所需求的動力學(xué)描述方程參數(shù)需求。是非線性特征的非常重要的一環(huán)。并且將結(jié)果與已得到的許多黑子的結(jié)論相比較，以得出其異同及聯(lián)系。 3、對于太陽暗條與黑子的相似性可看出太陽暗條很可能具有如同黑子一般的混沌特征。對此對暗條的K2熵進行計算，以確定其在系統(tǒng)隨時間變化而產(chǎn)生的不確定度的增長速度，同時也是確定其系統(tǒng)的復(fù)雜度。 4、太陽黑子具有眾所周知的極強的周期性，尤其以11年太陽活動周最為著名。其中對暗條的研究也表明暗條既有可能存在相似的周期性特征。并且，暗條的11年周期也被許多研究所證實。然而部分研究表明，太陽黑子暨太陽其他活動指數(shù)，如太陽耀斑、F10.7cm射電輻射等，都被發(fā)現(xiàn)有許多小于11年活動周但十分重要的活動周期現(xiàn)象。在這里，本文同樣將對這些小周期進行分析和挖掘。并希望通過小周期上與太陽黑子的相似性及相異性來分析太陽暗條與太陽黑子和其他太陽活動指數(shù)的相關(guān)性。
[Abstract]:Solar activity refers to a variety of phenomena including sunspots, solar flares, solar prominence and coronal mass ejections. The physical formation mechanism and long-term behavior characteristics have made great progress. Sunspots are the activities of the solar photosphere. But it is also closely related to the solar magnetic field. And as other solar activity, it is also closely related to the surface magnetic field of the sun. Therefore, the relationship between sunspots and sunspots needs to be clarified urgently. The phenomenon of solar dark strip as the coronal layer activity has an important relation with the surface magnetic field of the sun. Therefore, it is different from sunspot in the long-term activity of solar atmosphere and sunspot. Of great concern. And by clarifying differences and similarities, we can help explain what role sunspots play in the formation and eruption of dark strips, as coronal layer activity that is very relevant to sunspots. Many people think that it also has the nonlinear property and its periodicity similar to that of sunspot, in which the nonlinear property of sunspot has been studied extensively. For this reason, we hope to find out the similarities and differences and explain the differences and similarities by studying the nonlinear properties and periodicity of the dark strips. For this reason, we have done the following work:. 1. The number of solar dark strips per Carrington rotation from March 1919 to December 1989 observed by the Meteon Observatory in France is reconstituted from one dimension to several dimensions. The purpose of this phase space reconstruction is to internalize the data. The dynamic characteristics have been grasped in the high dimensional phase space in the form of phase trajectories. 2, calculate the correlation dimension of the data, The calculation of the correlation dimension can be used to analyze the parameter requirements of the dynamic description equation needed to generate the description data. It is a very important link of the nonlinear characteristic. And compare the results with many of the sunspots that have been drawn, In order to obtain its similarities and differences and links. 3. For the similarity between solar dark strip and sunspot, it can be seen that solar dark strip is likely to have chaotic characteristics as sunspot. The K2 entropy of dark strip is calculated in order to determine the growth rate of uncertainty caused by its variation over time in the system. It also determines the complexity of the system. 4. Sunspots are known for their strong periodicity, especially for their 11-year solar cycles. Studies of dark strips also show that there may be similar periodicity in dark strips. The 11-year cycle of dark strips has also been confirmed by many studies. However, some studies have shown that sunspots and other indices of solar activity, such as solar flares F10.7cm radio radiation, Are found to have a number of very important activity cycles less than 11 years of activity. This paper also analyzes and excavates these small periods, and hopes to analyze the correlation between solar dark strips and sunspots and other solar activity indices through the similarity and heterogeneity between small periods and sunspots.
