也许你应该尝试一些拼写变化:
communications implementation » communication implementation, communication implementations, computations implementation
computation implementation » computational implementation, population implementation, formulation implementation
based dimensions » based dimension, basic dimensions, based dimensioning
dimensions a49 » dimension a49, dimensions a, dimensions 4
a49 space » 4 space, 9 space, 14 space

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((communications implementation) or (computation implementation)) based dimensions a49 space~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((communications implementation) OR (computation implementation)) based dimensions a49 space.
• Adding a wildcard symbol may retrieve word variants: ((communications implementation) or (computation implementation)) based dimensions a49 space*.
