一．好的论文题目是成功的一半 好的论文，每一个部分都需要精雕细琢。我们先来看看Science, Nature 子刊上用的都是些什么题目，到底这些题目暗含哪些玄机以下是从2016年发表的论文中随机挑选的一些题目，我将其做了一下简单的分类： 1. Water splitting–biosynthetic system with CO2reduction efficiencies exceeding photosynthesis. (Science, 2016, 352, 1210) 类似: Scalable water splitting on particulate photocatalyst sheets with a solar-to-hydrogen energy conversion efficiency exceeding1%(Nature Materials 2016,15,611-615) 这种题目适合哪类文章适合于那种性能极其显着的文章（可以创纪录的文章），比如说Nocera et al. 的Science, 2016, 352, 1210，直接与光合作用进行对比，给人的震撼是非常强的。这种对比效果能够一下子抓住人们的眼球，吸引着读者进行阅读。 要点：使用这样的题目首先你的实验结果得够牛，你对于实验结果要足够自信，对于背景知识的了解得要足够深。因为取这样的题目意味着你要真正达到了某一个高度。如果明明有很多大海在那里，你个小池塘和小水坑进行比较，那么会闹笑话的。。。
