SCI论文的写作对于中国的学者来说最大的难题并非是内容，而是英语表达。对于我国的很多学者来说，SCI论文很难发表。可是我国现在很多的科研结构、高校都将SCI论文引入作为评价标准。也正是因为SCI论文越来越重要，大家想要提高投稿采纳的几率，必须要掌握SCI论文写作的技巧。下面大家就一起来看下SCI论文中怎样正确使用标点符号的吧！
1. 引导副词或者短语放在句首时，后面接逗号
举例：However the public is being inundated with stories aboutcancer-causing chemicals.
After 3 months the plants grown under phosphorus-deficient conditions were evaluated.
类似地副词：therefore thus However Nevertheless等
2. 当有三个及以上并列结构时，并列连词前需要加逗号(又称为连续逗号); 仅有两个并列结构时，不能用逗号
举例：Water sodium hydroxide and ammonia were the solvents.
Thered needles were collected washed with toluene and dried in a vacuum desiccator.
3. 动词(谓语)和主语之间不要加逗号
举例： The addition of substitutedsilanes to carbon–carbon double bonds has beenstudied extensively.（错误）

4. et al.之前不接逗号，除非有其他特别原因
举例：Saltzman et al. Saltzman M. J. et al. Saltzman Brown et al.
5. 日期后接逗号，如果只有月份没有日期，不用逗号;当句子中给出完整的年月日，那么年份后面也要接逗号

On August 18 1984 an extraordinary person was born.

举例：Iona College in New Rochelle New York is the CEO’s alma mater.
7. 采用逗号为句子插入引用语，但是当引用语作为主语时，不接逗号
举例：In the words of Pasteur “Chance favors the prepared mind.”
“Chance favors the prepared mind” is a translation from the French.

1. 除非引起歧义，否则单位简称后面不要接句号
特例：inch (in.) atom (at.) number (no.)
2. 姓名简写要用句号和空格隔开，但是在acknowledgement部分不需要空格
举例：J. E. Lennard-Jones M. S.Newman
R.C.McD. and C.R. thank Dr. Rose Allan forcarefully reading the manuscxxxxript.
3. 机构名的简写后不用加句号
举例：ACS CNRS NASA
4. 没有连词的独立分句（independent clauses）之间，加分号；采用连接副词或者过渡语“that is” “however” “therefore” “hence”“indeed” “accordingly” “besides” and “thus”等连接的独立分句之间，加分号。
举例：All solvents were distilled from an appropriatedrying agent; tetrahydrofuran and diethyl ether were also pretreated with activity I alumina.
The rate at which bleaching occurred wasdependent on cluster size; that is the degradation of the mononuclear clusterwas about 5 times faster than that of the tetranuclear cluster.
5. 从属小句和独立分句之间不能接分号
The activity on bromopyruvate was decreased; whereas the activity on pyruvate was enhan

ced.（错误）
The activity on bromopyruvate was decreasedwhereas the activity on pyruvate was enhanced.（正确）
本文先是介绍了逗号的使用方法，列出七种情况下是否应该使用逗号，应该在哪里使用逗号；而后介绍了句号和分号的使用方法，讲述了哪些情况下应该使用句号或分号；哪些情况下不使用句号或分号。可能很多人觉得标点符号只是小细节，不需要太过于关注。论文是由单词和标点符号组成的，倘若单词使用不当、语法错误甚至是标点符号使用有误，都会影响论文的质量。细节决定成败，大家一起努力吧！
