With the combination of attribute reduction in concept lattice, the model provides users with a semantic matching model based on concept lattice of theoretical value.
结合概念格属性约简等知识，该模型为用户提供一种有价值的基于概念格的语义匹配方法。

The influence of Mg concentration in doping on phase matching temperature, phase matching Angle, optical homogeneity, lattice parameter and density of the crystal is also stated.
掺镁浓度对晶体相匹配温度、相匹配角、光学均匀性、点阵常数和密度的影响。
