举一反三
- Which of the following does not belong to defects in castings?
- Because the castings of smaller engines are not so big and heavy， （） and cylinder block may be made in one piece.
- Material properties depend on the material microstructure, which in turn results from its compositions and processing.
- Shell-mold casting can produce many types of castings with close dimensional tolerances and good surface finish at low cost.
