也许你应该尝试一些拼写变化:
communities extensions » communities dimensions, community extensions, communities perceptions
communication control » communication concepts, communication culture, communication channel
control communities » control commodities, coral communities, content communities
tuple spaces » tuple space, type spaces, triple space
gauge spaces » large space, safe spaces
use spaces » phase spaces, whose spaces

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: communication control communities extensions ((((use spaces) or (tuple spaces))) or (gauge spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication control communities extensions ((((use spaces) OR (tuple spaces))) OR (gauge spaces)).
• Adding a wildcard symbol may retrieve word variants: communication control communities extensions ((((use spaces) or (tuple spaces))) or (gauge spaces))*.
