也许你应该尝试一些拼写变化:
irrigation requirements » irrigation equipment, nutrition requirements
requirements based » requirements a
based revision » base revision, based precision, based decision
arrays imaging » array imaging, assays imaging, pathways imaging
array sharing » arrays bearing, array imaging, way sharing
array string » array strong, arrays strings, array forming

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

• If you are trying to use Boolean operators, they must be ALL CAPS: irrigation requirements based revision ((((array sharing) OR (array string))) OR (arrays imaging))~.
• Adding a wildcard symbol may retrieve word variants: irrigation requirements based revision ((((array sharing) or (array string))) or (arrays imaging))*.
