Using the internally consistent thermodynamic data set, the software THERMOCALC and some available models of activity-composition relation for mineral phase, petrogenetic grids (p-T projection) for model systems and related compatibility diagrams, p-T.
变质相平衡是变质岩石学中最核心的问题之一,20世纪90年代以来,国外在这一领域取得了重要进展,即利用内洽性热力学数据库、THERMOCALC程序以及合理的矿物相活度模型定量计算模式体系中的岩石成因格子(P-T投影图)和有关的各种剖面图,如共生图解和针对特定岩石组分的p-T、p-x和T-x视剖面图等。
Furthermore, a class of lattices called V-generators dense lattices is introduced, which strictly includes the class of completely distributive lattices and the class of pentagon lattices.
设L是赋范线性空间上的子空间格,一个子空间是自反AlgL-模的充分必要条件被得到,当L是完全分配子空间格时,自反AlgL-模的二次交换子被描述,进而,本文引入V-生成子稠格,这是一种严格地包含了完全分配格和五角格的格类。
