The database can be searched by typing the desired search terms（e.g.，author（s），key word（s），and/or year）into the box below and selecting“搜索”.The search program identifies matches through a review of the titles，authors and year of the papers in the database；it does not scan the text of the body of the papers themselves.Since the search program only allows for a single level search of the database，if your selected search terms return too many papers，you will need to refine the search to reduce the number of database hits。
