It is found that, the law is induced mainly from regularly change of the content of p-quartz（ low coefficient of thermal expansion, high density） resulting from transformation of condensate depression and crystal phase（β-quartz→β-spodumene）.
分析发现,这主要是由于过冷度的变化和晶型转变（β-石英固溶体→β-锂辉石）引起的β-石英固溶体（低膨胀系数、高密度）含量的规律性增减所造成的。
