The results show that all alloys are mainly composed of a C14-type Laves phase with hexagonal structure and a V-based solid solution phase with b.

结果表明：所有合金均主要由六方结构的C14型Laves相和体心立方结构的钒基固溶体相所组成，其中钒基固溶体相以树枝晶的形式分布于C14型Laves相之中。

When secondary building units characteristic of zeolite Beta detected by FT-IR appeared in the reaction mixture in the absence of crystals of zeolite Beta, the pre-treatment was terminated. The aluminosilicate gel with seconding building units characteristic of zeolite Beta was led to ordered-channel hexagonal mesoporous molecular sieve by the interaction between liquid-crystal micelles formed by the self-assembly of surfactants and pre-treated alumiosilicate gel. Therefore, the mesopore wall of SBU mesoporous materials showed the structural character of zeolite Beta.

当反应混合物出现用FT-IR可以检测到的Beta沸石次级结构单元且又没有生成Beta沸石晶体时，即刻终止预处理过程；然后利用表面活性剂超分子自组装形成的液晶胶团与经过预处理的无机物种通过界面作用把含有Beta沸石次级结构单元的无机物种导向为有规整孔道结构的六角中孔分子筛，这种SBU中孔材料的孔壁因而具有Beta沸石的结构特征。

For wurtzite-type crystal, [Zn-S4]6- and [Zn-S4]6+ with different crystal positions distribute in the form of layers along c axis, where the two layers of tetrahedrons whirl 60 around c axis, so the crystal is mainly like hexagonal cone.

在纤锌矿型晶体中，[Zn-S_4]~(6-)和[Cd-S_4]~(6-)四面体沿c轴呈层状分布，上下两层四面体的结晶方位不同，两层四面体绕c轴旋转60°，晶体的结晶形貌为六方锥状。

The FTIR spectra consists of two absorption bands at about 780 cm^(-1) and 1 380 cm^(-1), which suggests the existence of the hexagonal phase of BN.

红外光谱分析表明，BN薄膜结构为六角BN相（1380 cm^(-1)和780 cm^(-1)）。
