也许你应该尝试一些拼写变化:
communication contributions » communication distribution, communication conclusions, communication collections
contributions methods » contribution method, conditions methods, contributions memory
methods dimension » methods diffusion, ethics dimension, metholodgy dimension
shape spaces » shape space, shared spaces, state spaces
safe spaces » state spaces, scale spaces, life spaces
use spaces » tuple spaces, phase spaces, gauge 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 contributions methods dimension ((((use spaces) or (safe spaces))) or (shape spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication contributions methods dimension ((((use spaces) OR (safe spaces))) OR (shape spaces)).
• Adding a wildcard symbol may retrieve word variants: communication contributions methods dimension ((((use spaces) or (safe spaces))) or (shape spaces))*.
