黑子群

文中将第22周上升段（1987.1.1&1988.7.31）的太阳黑子群和X射线耀斑按经度带作了极大熵谱估计。

The periods of the McIntosh classifications of sunspot groups and X-ray flares of every longitudinal zone ( from January 1,1987 to July 31,1988 ) are estimated by using the Maximum Entropy method .

从物理性质方面来看黑子群实际上有它自身的结构。

In view of its physical nature such a sunspot group actually has a structure of its own .

依据对太阳活动的统计研究，简要分析了三个大黑子群活动的差异。

The results show that active longitude band and main hemisphere of solar activity are very important information for the short term prediction of solar activity .

因此，区分出异常磁结构黑子群对质子耀斑的预报和机制研究可能是有意义的。

Thus , the seperation of the abnormal configurations may be meaningful in view of the importance in the forecasting and studying the mechanism of proton flares .

结果可用于解释：多带耀斑的产生、双拱磁结构和拉长的复杂黑子群上空的磁场结构。

The results are used to interpret the producing of multiple-ribbon flares , two-arch magnetic structures and the structures of the magnetic field above the elongated complicated groups of sunspot .

质子耀斑后，磁绳的松弛，黑子群可能会出现反向旋转，强的剪切过程和质子耀斑可能会再度出现。

After proton flares , due to the slack of the flux rope sunspot groups can rotate in the inverse direction , and strong magnetic shear configurations and proton flares occur once again .

磁场结构的特点是黑子群磁极性排列的倒置、δ磁结构的存在和磁场梯度的剧烈变化。

The characteristic features of the magnetic configuration are the inverted arrangement of the magnetic polarities of the sunspot group , the existence of the 3 magnetic configuration and the violent changes of the magnetic field gradient .

黑子群的旋转是质子耀斑活动区的又一重要特征，黑子群的旋转方向与日面南、北半球无关。

Another important characteristics of the active regions of proton flares is the rotation of the sunspot groups . The rotative direction of the sunspot groups have no connection with southern and northern hemisphere on solar disk .

它们的大小足以和地球匹敌，很多时黑子是整群出现的。

They are comparable to the size of the earth and usually , sunspots appear in groups .

UXAri在2000年的主要黑子活动区分布在高纬、中纬和低纬地区，其中，高纬和中纬地区的黑子群长期存在。

The main spot features of UX Ari are distributed in high-latitude , middle-latitude , and low-latitude regions in 2000 . The features in high-latitude and middle-latitude regions are long-terra phenomena .
