Research on reduction of implications in G-D base in concept lattice theory

概念格理论中的G-D基蕴涵约简研究

By introducing the lattice theory and considering a cubic unit cell, the water permeability of concrete is obtained for several lattice arrangements of aggregates, which indicates that the arrangement of aggregates is an important factor that affects the water permeability of concrete.

引入晶格理论，取立方体单元胞，求解混凝土骨料几种不同规则排列下的混凝土相对水渗透系数，计算结果表明骨料排列是影响混凝土水渗透系数的重要因素。

This paper discusses the nature of semi-ring absorbable element by the application of semi-ring and lattice theory and achieves some better results in the aspects of semi-ring absorbable element in the semi-ring homology, the strong ideal, the regularity and the lattice theory.
