STN on the Web b. STN Express c. STNEasy STN on the Web和STN Express都是指令检索界面，其检索功能完全一样，区别在于STN on the web是通过网页访问，而STN Express是通过客户端访问。 STNEasy采用的是对话框似的访问方式，无需使用指令，操作方法简单，因此不能达到对文献检索精而全的要求。,STN检索界面,5,STN中可使用的指令,在STN中，可用的指令超过20个 /training/stncommands/index.html,其中，第一列是最常用的5个指令,STN中可使用的指令,STN中可使用的指令,6,联机前的准备工作,7,联机前的准备工作 确定要查找的关键词 查找同义词、不同拼写方式和缩写 使用合适的截词符 使用合适的连接符,8,同一主题的文献，作者有可能使用不同的同义词和缩写 一些了解同义词、缩写的方法 和同事讨论 做一次初次检索在得到的记录中寻找替代词 使用在线词典或词库 (将在高级检索技巧中讨论) 尝试一些网站, e.g. / /,查找同义词和缩写词,9,使用合适的截词符,使用截词符可以检索到包含相同一组字母的词语。从而做到省钱和省时 STN中的截词符号有,使用合适的截词符,10,在字/词间使用合适的连接符,在STN中，使用的连接符有：,11,练 习,请确定下面检索问题的主要概念及其同义词，并用合适的连接符建立检索式 检索问题: 1.

A comparison study of 10 UV filters AUTHOR(S): Gonzenbach, H.; Johncock, W.; De Polo, K. -F.; Blankenburg, G.; Fohles, J.; Schafer, K.; Hocker, H. CORPORATE SOURCE: Roche Vitamins and Fine Chemicals, Geneva, Switz. SOURCE: Cosmetics ISSN: 0361-4387 PUBLISHER: Allured Publishing Corp. DOCUMENT TYPE: Journal LANGUAGE: English CLASSIFICATION: 62-3 (Essential Oils and Cosmetics) ABSTRACT: UV-induced alterations in virgin blond Caucasian hair and in virgin black Asian hair were assessed in a preliminary study by measuring color changes, mech. properties (single hair friction, combing force and tensile strength), FTIR spectroscopy and classical amino-acid anal. The amino-acid anal. seemed the most sensitive test. Next, virgin blond Caucasian hair were treated with 10 protective test formulations and exposed each to simulated sunlight. The different results can be attributed to qual. differences in deposition induced by the formulation.,原始文献有7页,作者所写,简写,18,CAplus中的一篇记录,接上页),SUPPL.
