【正文】 bout 40 to 60 central.[22] ? Frequency per yearSolar eclipses can occur 2 to 5 times per year, at least once per eclipse season. Since the Gregorian calendar was instituted in 1582, years that have had five solar eclipses were 1693, 1758, 1805, 1823, 1870, and 1935. The next occurrence will be 2206.[23] 樣例文本 3 ? If the date and time of any solar eclipse are known, it is possible to predict other eclipses using eclipse cycles. Two such cycles are the saros and the inex. The saros is probably the best known and one of the most accurate eclipse cycles. The inex cycle is itself a poor cycle, but it is very convenient in the classification of eclipse cycles. After a saros finishes, a new saros series begins one inex later, hence its name: inex. A saros lasts 6, days (a little over 18 years), which means that after this period a practically identical eclipse will occur. The most notable difference will be a shift of 120176。太陽因緯度不同的較差自轉(zhuǎn)造成它的磁場線隨著時(shí)間而糾纏在一起，造成磁場圈，從太陽表面噴發(fā)出來，并觸發(fā)太陽形成系距性的太陽黑子和日珥 （參見磁重聯(lián)）。太陽磁場會(huì)導(dǎo)致很多影響，稱為太陽活動(dòng)，包括在太陽表面的太陽黑子、太陽耀斑、和攜帶著物質(zhì)穿越太陽系且不斷變化的太陽風(fēng) [63]。太陽因緯度不同的較差自轉(zhuǎn)造成它的磁場線隨著時(shí)間而糾纏在一起，造成磁場圈，從太陽表面噴發(fā)出來，并觸發(fā)太陽形成系距性的太陽黑子和日珥 （參見磁重聯(lián)）。太陽磁場會(huì)導(dǎo)致很多影響，稱為太陽活動(dòng)，包括在太陽表面的太陽黑子、太陽耀
