标题是读者的向导,直接影响到新闻的宣传效果。科技新闻最明显的特点就是技术性强,标题比一般新闻难标,不容易做到生动活泼。因此,要注意读者文化层次、结构的不平衡性以及科技新闻本身特点这两方面的因素,深入构思,精心制作科技新闻标题。科技新闻标题要根据新闻本身的要素标出主要事实,基本要求就是让读者看懂,使读者第一眼就能被标题吸引,并对科技新闻事实有一个大概的了解。例如下面这则标题:
The title is the reader’s guide, a direct impact on the publicity of the news. The most obvious feature of technology news is its strong technicality. Titles are harder to read than the average news, and are not easy to be lively and vivid. Therefore, we should pay attention to the reader’s cultural level, structural imbalance and the characteristics of science and technology news of these two factors, in-depth ideas, elaborate science and technology news headlines. The headline of science and technology news headlines must mark the main facts according to the elements of the news itself. The basic requirement is to let the readers understand it so that the readers can be attracted to the headlines at first sight and have a general understanding of the facts about science news. For example, the following title:

高等植物在生长过程中经常受到干旱、高温、低温、高盐等非生物的胁迫,植物能够快速感知这些不良环境的变化且主动适应,而适应的过程就涉及到细胞内与细胞间的信号传递。蛋白质的磷酸化和去磷酸化是生物体内能量代谢以及信号传递中的重要生化反应,而蛋白质的磷酸化主要是在蛋白激酶的催化下完成的。对小麦蛋白激酶的研究将为小麦的生理代谢和耐胁迫性的机制提供有利的依据。本实验以小麦中蛋白激酶WK为诱饵通过酵母双杂交筛选得

水稻(Oryza.Sativa)是世界主要的粮食作物。水稻成熟种子中胚乳约占总质量的90%。胚乳细胞的发育状况直接决定着水稻的产量和品质。稻米胚乳垩白直接影响稻米外观品质、碾磨加工品质和蒸煮食味品质。因此研究胚乳发育进程及淀粉合成机理对于实现水稻的高产、优质具有重要的意义。利用CRISPR/Cas9技术对调控稻米脱支酶基因PUL定点编辑,获得了一套有重要育种价值的pul突变体。首先设计两个guid
