处理代码 (TR)
• Applications • Bibliographic • Economic aspects • General or review • New developments • Practical • Product review • Theoretical • Experimental
A description of the actual use or implementation of an instrument, device, method, technique, computer program or physical effect, where a specific application is described
Documents containing a bibliography or significant list of
referencesDocument deals with cost, pricing, market forecast, etc.
Documents give an overall view of a subject. General approaches, overviews & introductory articles
Document is meant to be of direct practical use and is of particular interest to engineers & design staffIntroduced in 1985. Includes
product comparisons, tables & buyer’s guidesSubject matter is generally
theoretical or mathematicalDocuments describing an experimental method, observation or result. Includes apparatus used, calculations & experimental results
Used where a claim of novelty (in the patent sense) might be made
