These faces grow so rapidly that they have priority to appear and retain as the melt supercooled.
{ 3 2 1 }面族、{ 2 1 1 }面族和 { 1 1 1 }面族都是按 [GeO4]4-四面体以顶角相连的化学键链生长发育的 ,生长速度快 ,优先显露 ,在熔体急冷时保留下来。
20) samples were prepared by slow-cool-from-melts and the influences of AgSbTe2 content on the microstructure and thermoelectric properties were investigated.
采用熔融缓冷法制备了组成为(AgSbTe2)x(PbTe)1-x(x=0。
