Scientific Citation Index (SCI), institute for scientific information, USA (? Eugene garfield, ISI), founded the citation database in Philadelphia, USA on 1957. SCI (Science Citation Index), EI (Engineering Index) and ISTP (Science and Technology Conference Index) are three world-famous retrieval systems for scientific documents, which are internationally recognized as the main retrieval tools for scientific statistics and scientific evaluation.
The number of words in sci abstracts is usually more than that in China, but it should not be too much in China, and about 3000-5000 words is more suitable. It is very common for sci to summarize more than 10 thousand words. Many researchers want to publish a summary, mainly because it is relatively easy to summarize, no experiment is needed, and it is relatively easy to check repetition. However, the summary writing is not simply a list of materials, which needs attention. The summary must have the author's own analysis, thinking and summary.
