关 键 词：metamorphic reaction Si-O distance grand mean value
摘 要：The grand mean values of Si-O distances in both the left and the right sides of 33 metamorphic reaction equations have been calculated on the basis of data of single crystal structural refinement *** results showed that the grand mean value of Si-O distances tends to decrease at high temperature,whereas that tends to increase at high pressure during a metamorphic reaction.
