也许你应该尝试一些拼写变化:
communication circuit » communication circuits, communications circuits, communication current
element dimensions » elements dimensions, relevant dimensions, equipment dimensions
circuit element » circuit elements, circuits elements, circuit placement
tuple spaces » tuple space, type spaces, triple space
gauge spaces » large space, use spaces
safe spaces » state spaces, shape spaces, scale 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 circuit element dimensions ((tuple spaces) or (((gauge spaces) OR (safe spaces))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication circuit element dimensions ((tuple spaces) OR (((gauge spaces) OR (safe spaces)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication circuit element dimensions ((tuple spaces) or (((gauge spaces) OR (safe spaces))))".
• Adding a wildcard symbol may retrieve word variants: communication circuit element dimensions ((tuple spaces) or (((gauge spaces) OR (safe spaces))))*.
