您见过这样格式的论文题目吗？
（王德华）
写论文的人都知道论文题目的重要性。一个好的论文题目，吸引人的论文题目，恰到好处的论文题目，简明扼要的论文题目，是读者决定是否进一步阅读下去的关键因素。在信息时代，每天发表的论文都不计其数的情况下，多数论文也只能是浏览一下论文题目而已，能够阅读摘要的就少多了，能够阅读全文的就很有限了，能够认真阅读（精读）的全文的论文就更是有限了。
记得早些时候，长辈科学家们曾教导我们写学术论文时，题目中是不能出现动词的，也就是说不能用一个句子作为论文的题目（相应地在摘要中要用第三人称或被动语态）。后来逐渐发现国际上有些学者的论文题目中使用了动词，直接用论文的结论作为论文的题目（一个完整的句子）。也有些学者至今不建议用结论作为一篇论文的题目。
今天查文献时，在著名期刊《生态学、进化和系统学年评》上发现了一篇论文的题目格式很奇特，应属于新的格式，用类似数学等式的格式作为论文的题目。这种方式我还真是第一次见，感觉很新鲜。如下：
Walsh B and Blows MW. 2009. Abundant Genetic Variation + Strong Selection = Multivariate Genetic Constraints: A Geometric View of Adaptation. Annu. Rev. Ecol. Evol. Syst. 40:41–59.
Abstract
Evolutionary biology has struggled to explain the coexistence of two basic observations: Genetic variation is found in almost all traits in the presence of strong natural and sexual selection in natural populations. These two observations are in direct conflict as such selection should deplete genetic variation. Furthermore, the presence of genetic variation in a trait, and selection acting on that trait, is often not sufficient for the trait to respond to selection. Here, we bring together geometric perspectives on mutation, selection, and genetic variation and show how the perceived incompatibility between these two observations is a consequence of taking a trait-by-trait approach to the multivariate problem of genetic variation and selection.We conclude that the simultaneous presence of widespead genetic variation in, and strong selection on, individual traits indicates that substantial multivariate genetic constraints are likely to be present in natural populations.
