relatedto the sunlight exposure and mutation of BRAF gene, whereas the C2 are not.

The difference between the A1 and A2 may be determined by the differentenvironmental and cellular factors of the C1 and C2.

These results indicated that X only stimulated cell growth at a highconcentration.

After supplementation with X, A growth was stimulated, but mitoticactivity declined rapidly after a few passages.

These effects were dose-dependent at the range from --- to --- M 统计学

The differences of X and cell counts between the control and test groupswere statistically significant (cell number: 0.05 > P>0.01 atconcentrations of ---M in complete medium, at --- M in --- medium, and P<0.01 at concentrations of --- M in --- medium).

The differences between the X treated culture and negative controls weresignificant at concentrations of 10-6-10-5 M

In the study on/(of the) cAMP-deleted medium, the number of cellsincubated with X at all concentrations showed no significant differencecompared with the negative controls.

This method provides a valuable source of large numbers of Cs, which canbe used to study their biological behavior, to compare with the A; and to comparethem to their malignant counterparts in the exploration of the pathogenesis of A.

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。。。

SCI论文——英文写作的语言技巧总结

我觉得写文章之前要先有思路，你怎么去写怎么写的和别人不同，有新意。这里面的文章很大，我也说不透，只是参透了一二，和大家分享，望大家不要耻笑。我毕竟是个硕士研究生。 我觉得论文写很简单，主要是能够发表出去。下面我简单讲下我的思路。有相同或不同见解的留下言，共同交流，一起进步。 文章的第一步要有图，也就是说首先把图做的漂漂亮亮的，不管是SEM，TEM，Uv-vis，FTIR，还是效果图。图片放到你的文章里就是你的思路，图片放好了你的思路就出来了，这是就关键的过程，放图的过程中你要考你怎么写，你的文章新的地方在哪?;图做好了也放好了，就是写文章了，写文章也很快了，因为思路有了你的文章也构思好了。我在这里给出我写文章时的程序。对于文章主体部分，我觉得先写Results and discussion，写完了根据其内容下个Conclusion，然后根据Conclusion写Abstract(因为它们俩有些许的类似)，而后补充Experimental。论文发表qq1813831290最后也是最难写的地方Introduction，这个让审稿人一看就能知道你的文章的水平，所以写好Introduction是关乎论文是否收录的关键所在。我和外国审稿人专家关于审稿交流过意见，他们也是这样认为，他们也认为Introduction是整个文章的脸面，这是他们主要审的地方，在这里能看到你的创新点，创新点不够直接refuse;Introduction写的还可以的话，就看Results and discussion，这部分其实主要看的是图，你的图的清晰度质量，以及性能图。我审过一篇Journal of Hazardous Materials上面的文章，我也是这样审的。当然是咱们国内某名牌大学的文章，做的是催化，我也是做这个的不知为什么编辑发来让我审，我也感觉很莫名。后来编辑告诉我和我的文章有些类似还称我是专家，教授…… 下面我引用了一些总结的写作经验，我觉得很有用。大家认真看看，在此先祝福大家论文高中，硕果累累不减当年勇时： 1.前言部分 1.1如何指出当前研究的不足以及有目的地引导出自己的研究的重要性 通常在叙述了前人成果之后，用However来引导不足，比如 However,little information... little attention has been devoted to… little work... little data/little research or few studies/investigations/few attempts have been don on… or none of these studies

Summary的写作技巧和常见句型

S u m m a r y 的写作技巧和常见句型 、概括原文 一）阅读 1. 读懂文章读文章的时候，要养成良好的阅读习惯，划划写写，英文阅读的时候，用铅笔轻轻划出重点词汇。 认真阅读给定的原文材料。如果一遍不能理解，就多读两遍。阅读次数越多，你对原文的理解就越深刻。 2. 拆分文章按照作者的思路，把文章分段，每个段落用几个词，几个短语概括。尽量简短，精 炼。 段落中心句，在段落的开头或末尾。有时也会变态的在当中。 3. 概括主旨写出文章的thesis, 一句话概括文章的主旨。 二）基本结构和技巧 1.重新拟定标题给summary 起一个标题。用那些能概括文章主题思想的单词、短语或短句子作为标题。也可以采用文中的主题句作为标题。 2. 阐述观点 摘要应全部用自己的话完成。不要引用原文的句子。写概述的时候，如果能够明确是他人写作的文章，注意要把作者的名字放在第一句（或者是接着写出要阐述的main ideas （主要观点）和supporting points （对主要观点的the author .. ）。

支持）。 3. 词汇运用 注意概述的cohere nee （连贯性），运用好tran siti on words （过渡 词） , like however, furthermore, nonetheless, besides, therefore etc. 4. 删除细节 只保留主要观点。 5. 选择一至两个有代表性的例子 原文中可能包括5 个或更多的例子，你只需从中筛选一至二个例子。 6. 把长句变成短句，把长段的描述变成短小、简单的句子。 He was hard up for money and was being pressed by his creditor. 可以概括为：“ He was in finan cial difficulties. His courage in battle might without exaggeration be called lion- like. ” 可以概括为：” He was very brave in battle. He was hard up for money and was being pressed by his creditor. 可以概括为：“ He was in finan cial difficulties. 6）你还可以使用词组代替整句或者从句。请看下面的例子： Beautiful mountains like Mount Tai, Lushan Mountain, and Mount Huang, were visited by only a few people in the past. Today, better wages, holidays with pay, new hotels on these mountains, and better train and bus services, have brought them within reach of many who never thought of visiting them ten years ago. ” 可以概括为：” Beautiful mountains like Mount Tai, once visited by only a few people, are today accessible to many, thanks to better wages, paid holidays,
