According to the Vegard's law and density functional theory of quantum mechanics, the lattice match conditions of Boron-contained arsenide and antimonide quaternary materials have been deduced, the bandgap properties of such quaternary materials have been theoretically analyzed, and the bandgap bowing parameters of all ternary compounds included have been theoretically calculated.

依据维加德定理和量子力学中的密度泛函理论计算出含硼砷化合物和含硼锑化合物四元系材料与GaAs、Si晶格匹配的条件及其带隙性质，同时计算出上述四元系材料所含三元系材料的能带弯曲参数，进而推导出BInGaAs、BInAlAs、BGaAsSb和BGaPSb四元系材料的发光波长与硼元素并入比例的关系。

Furthermore, the chemical interaction between interstitial boron atom and antiphase boundary was also discovered.

间隙硼原子与反相畴界之间存在着类似铃木气团的化学交互作用。

The beneficial effects of homogeneously distributed boron inside grain on lowering the energy of antiphase boundary and improving brittleness are weakened.

The results show that, Main crystallization phase of glass ceramic was hedenbergite, and the minor crystallization phases were augite and hypersthene. With increasing boron mud addition, the amount and the size of crystallization phases both gradually increased, the configure of crystallization phases transformed from the branch, the ball, to the block. The transformation from the branch to the ball could improve the properties of glass ceramic, and the transformation from the ball to the block could worsen the properties of glass ceramic.

结果表明：矿渣微晶玻璃的主析晶相为钙铁辉石，次晶相为普通辉石和紫苏辉石；随着硼泥配入量的增加，矿渣微晶玻璃中晶体的析出量和尺寸均逐渐增加，晶体形态由枝晶向球晶及块状晶体过渡；枝晶向球晶转变可以明显改善矿渣微晶玻璃的性能，而球晶向块状晶体的转变则恶化了微晶玻璃的性能。
