晶格结构

In chapter III,we investigate the lattice dynamical properties of tetragonal La2CuO4single crystal using a five parameter rigid-ion model.

在第三章中，我们用一个五参数的Rigid-ion模型对正方结构La2CuO4单晶的晶格动力学性质进行了研究。

It was experimentally verified that Mo-La2O3 cathode had higher thermionic emission effectiveness and lower operating temperature than Th-W tube.

Mo与 Mo2C 的界面高分辨晶格像直接显示了碳化层与基体界面结构，晶体取向关系为[210] Mo2C ‖[100] Mo ，碳化层与基体结合良好。

In addition, laser induced thermoelectric voltage effect was measured for the first time in these superlattices thin films. This experimental phenomenon illustrate that this kind of artificial atomic layer thermopile structure possesses Seebeck anisotropy.

在超晶格薄膜中首次发现了激光感生热电电压效应，说明这种人造原子层热电堆结构具有Seebeck系数各向异性。

ZnO has wurtzite structure, and its lattice parameters are a=0.3249 nm and c=0.5206 nm.

ZnO具有六方纤锌矿结构，晶格常数a = 0.3249 nm， c = 0.5206 nm。

The selected area electron diffraction pattern also shows that the epi-layer is 3C-SiC film with a zinc blende structure,and the calculated lattice constant is 0.4362nm.

选区电子衍射花样标定结果再次说明外延薄膜为闪锌矿结构的3C-SiC，计算的晶格常数为0.4362nm。

The nanocrystallite shows the cubic zinc blende structure, and the average size is 55nm, the minimum size is 3nm. The lattice constant is 5.869×10~(-10)m. The nanocrystallite shows the obvious quantum size effect.

Lead zirconate titanate PbZr0.5Ti0.5O3 thin films of various thickness were prepared by a modified sol-gel method on Pt(111)/Ti/SiO2/Si(100) substrates. The films were well crystallized and had single perovskite phase structure at an annealing temperature of 600℃.

采用改进的溶胶-凝胶技术，在Pt(111)/Ti/ SiO2/Si(100)基底上制备了不同厚度的Pb (Zr0.50Ti0.50)O3薄膜，在600℃的退火条件下获得了晶格完善的钙钛矿结构。

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。

The structure measurement indicates that only a small amount of Bi3+ ions can not enter the A-site of La2/3Ca1/3MnO3 lattice. Because of the low melting behavior of bismuth oxide, the superfluous Bi will segregate as insulating bismuth oxides and bismuthate. Because of the segregation of Bi, the surface of the main phase has different ferromagnetic property from that of the core, namely the magnetic inhomogeneity of the samples is enhanced, which results in the broader ferromagnetism-paramagnetism transition and magnetoresistance plateaus in samples with the high Bi content.

结构测试表明Bi并不能进入La2/3Ca1/3MnO3的晶格锰位，由于A位元素的过量和铋氧化物的低熔点特性，烧结过程中Bi元素析出形成了绝缘性的第二相；并且Bi的析出导致样品主相的表面存在与主相体心磁性质不同的铁磁相，即样品的磁不均匀性增强，使得高Bi含量的样品表现出宽的铁磁-顺磁转变和磁电阻平台效应。

FT-IR spectra shows that the polyaniline is present primarily in the emeraldine salt form, and the polymeric chains interact with inorganic framework, most likely via V=O…HN hydrogen bonding. XRD,TG and DSC indicate that the lamellar structure of the V_2O_5 is preserved, PAn chains eliminate water form the interlamellar region and are partially inserted between the layers, and exist with extended-chain conformation owing to the confined environment.Electrochemical investigation in the range of 1.8~3.8V vs.

红外光谱表明复合物中PAn主要以导电聚苯胺盐的形式存在，PAn链与V_2O_5晶格之间可能形成了V=O…HN氢键。X射线衍射、热重和差示扫描量热证实了PAn/V_2O_5复合物保持了较规整的层间排列结构，PAn取代了V_2O_5干凝胶中的层间水而部分嵌入其片层间，由于受空间的限制，PAn分子链以比较伸展的链构象存在。
