How to Write an Abstract The rules for writing an abstract (摘要) are almost the same to those for writing the summary of an investigation report. In an abstract you make an outline of the problem and the purpose of your investigation, mention very briefly how you conducted the investigation or tests, describe your main findings, and make the conclusions. All these must be done in as few words as possible: ideally, your abstract will be about 125 words long and never more than 250 words. From the abstract, readers must be able to decide whether the information you provide in the scientific paper or report is particularly interesting to them and whether they should read further. Because a scientific paper is written for readers who generally are familiar with your technical or scientific discipline (学科), you may use technical terminology (术语) in the abstract. The abstract should be written last, when the Whole paper has been written, so that you can make an abstract of the brief details you need from what you have already written.
