The results showed that Eu(superscript 3+) and Li(superscript +) were successfully doped into the crystal lattice of SrZnO2 matrix and Eu(superscript 3+) preferentially occupied Sr(superscript 2+) asymmetry cationic sites, thus emitting 615 nm red light originated form 5D0→7F2 transition.

结果表明，Eu(上标 3+)和Li成功掺入SrZnO2基质中，Eu(上标 3+)离子在基质中主要占据Sr(上标 2+)离子不对称性格位，发射来源于5D0→7F2615nm为主的红光。

Crystal lattice constants are close to other experiment results. Three kinds of chemical bonds exist among Mg and B atoms, between magnesium and boride is ionic bond and metallic bond is the predominant interaction in the layer formed by magnesium atoms. A strong covalent bond in the form of sp2 hybrid between boride atoms is the most important factors which can affect the transition temperature of MgB2. Population analysis clearly shows that electrons are transferred from Mg to B, as a result, the electron-phonon coupling in the layer of B is very strong.

In this model the carbon atom amount, which exist in austenitic crystal lattice, decided the structure size.

在这一模型中决定&有序簇聚结构&尺寸的一个重要因素是奥氏体晶格点阵中实际固溶的碳原子数量。

TEM shows that drying by direct heating might result in hard aggregation of the tourmaline powder, while hard aggregation might be avoided by azeotropic distillation. Raman spectroscopy reveals that there are O_H and C_H on the surfaces of the tourmaline powder obtained by azeotropic distillation, which indicates that butoxy is chemically adsorbed on the surfaces of tourmaline particles, but not adsorbed on those formed by direct drying. X_ray powder diffraction shows that the intensity of diffraction peaks decreases after grinding. There is no damage to the tourmaline crystal lattice in the process of direct heating, azeotropic distillation, or ultrafine grinding.

透射电镜分析结果表明，直接加热脱去水或正丁醇会使电气石超细颗粒发生硬团聚，而共沸蒸馏法则可有效防止硬团聚的产生；拉曼光谱结果表明，共沸蒸馏法制备的电气石粉末表面存在O—H和C—H键，说明正丁醇在颗粒表面为化学吸附，而直接干燥法得到的电气石粉末表面则没有；X射线粉晶衍射结果表明，研磨过程降低了粉末衍射峰的强度，但直接加热干燥和共沸蒸馏干燥均未破坏电气石的晶格结构。
