| 摘 要： | 1. Decomposition of supersaturated Solid Solution(Cont'd) X-ray diffraction and electron microscope observations, and the measurement of physical proper-ties such as electrical resistivity and heat content, have shown that in supersaturated solid solutionsthere often develops[1] a fine-scale clustering into a zone structure. Although not completely proved,it seems most likely that these G. P. zones, So-named after their discoverers, A. Guinier and G. D.preston,are produced by spinodal decomposition,They form homogeneously on a fine scale through-
