一篇天文学论文应该写多久才能增加影响力？
How long should an astronomical paper be to increase its Impact?
摘要：
天真地，人们会期望较长的论文具有更大的影响力（即，引用更多）。我通过选择2000年至2004年期间出版的A&A，AJ，ApJ和MNRAS的所有（约30，000）参考论文来测试这一预期。选择这些特定年份是为了使分析的论文不会太“新鲜”，但同时每篇文章的长度可以通过ADS获得。我发现，在这四个主要天文学期刊上发表的较长的论文平均被引用的次数更多，引用次数的中位数从2-3页长的文章的6次增加到50页长的文章的50次左右。然而，我确实观察到了一个显著的“信件效应”，即ApJ和A&A 4页长的文章被引用的次数超过了5-10页长的文章。此外，极少数最长（>80页）的论文实际上被引用的次数少于较短的论文。对于单个期刊，每篇论文的引用中位数从约9，300篇A&A论文的11篇增加到约5，300篇MNRAS论文的14篇，约2，550篇AJ论文的16篇，约12，850篇ApJ论文的20篇（包括ApJ Letters和Supplement）。最后，我提出一些半幽默的职业建议，特别是针对一年级的研究生。
英文摘要：
Naively, one would expect longer papers to have larger impact (i.e., to be cited more). I tested this expectation by selecting all (~30,000) refereed papers from A&A, AJ, ApJ and MNRAS published between 2000 and 2004. These particular years were chosen so papers analyzed would not be too "fresh", but at the same time length of each article could be obtained via ADS. I find that indeed longer papers published in these four major astronomy journals are on average cited more, with a median number of citations increasing from 6 for articles 2-3 pages long to about 50 for articles ~50 pages long. I do however observe a significant "Letters effect", i.e. ApJ and A&A articles 4 pages long are cited more than articles 5-10 pages long. Also, the very few longest (>80 pages) papers are actually cited less than somewhat shorter papers. For individual journals, median citations per paper increase from 11 for ~9,300 A&A papers to 14 for ~5,300 MNRAS papers, 16 for ~2,550 AJ papers, and 20 for ~12,850 ApJ papers (including ApJ Letters and Supplement). I conclude with some semi-humorous career advice, directed especially at first-year graduate students.
