Microchemical variations

Extensive microstructural and microchemical variations occur in the bulk superconductors which are often nonstoichiometric. The... 

The mean valmber the dry weight, (3.95 0.20) X 0 10 gram, agrees with results obtained in microchemical analyses of samples containing many cells. Such analyses cannot, of course, reveal the individual variations that appear in Table 11-3.
