Shrinkage
Definition:
(n.) The act of shrinking; a contraction into less bulk or measurement.
(n.) The amount of such contraction; the bulk or dimension lost by shrinking, as of grain, castings, etc.
(n.) Decrease in value; depreciation.
Example Sentences:
(1) Tumor shrinkage was documented by A-scan ultrasonography in all but one patient.
(2) Results suggest that these resins should be used with some method to compensate for the shrinkage, when used as index material.
