Using the bond-fluctuation-model and vacancy-diffusion-algorithm,the microphase structure, segment profile and structure factor of molten symmetrical AB diblock copolymer confined between two impermeable plate surfaces are simulated by Monte Carlo method based on simple cubic lattice.

采用改进的键长涨落空穴扩散算法对平板狭缝中的对称两嵌段共聚高分子熔体的微相分离形态、密度分布以及结构因子进行了MonteCarlo模拟。

Then the structure unit of hexangular lattice is found according to the principle of invariable symmetry. Renormalization transformation is processed when we regard the structure unit and the growth model as graphs before and after transformation respectively. After choosing the11thermodynamic function fugacity as parameter, we can write out the partition functions before and after transformation and the formula of renormalization transformation. At the same time, we also work out the fixed points of transformation.

然后根据对称性不变的原则，从整体晶格中选取结构单元，把结构单元和生长模型分别作为重整化变换前、后的图形来进行重整化变换，选取热力学函数易逸度为参量，写出了重整化变换前后的配分函数和重整化变换关系式，求出了这一变换的不动点。

There exists isomorphous replacement in the rutile structure, and the most prominent feature is the average content of oxides, being 1.22%, 0.39%, 0.35% and 0.22% for V 2O 5, Fe 2O 3, ZnO and CuO respectively. They substitute Ti 4+ in octahedra. The valence of V is 5, and its polyhedron is trigonal bipyramid, which causes the lattice distortion, breaks the raw octahedron symmetry into square bipyramid, and produces the microstrains in the structure.

天然含钒金红石平均含V2O5可达1.22％，Fe2O30.39％，ZnO0.35％，CuO0.22％，这些金属离子可替代八面体中Ti^4 。V以5价形式存在，配位多面体呈三方双锥，其在晶格内部对Ti的替代导致晶格畸变，打破了配位多面体原有的八面体对称而呈四方双锥的几何形态，并产生结构微应力。

XRD showed hexagonal wurtzite structure. Room-temperature PL spectra of perfectly overcoated CdSe/ZnS only showed a narrow band edge emission. Emission peak was great red-shifted relative to absorption and the shift increases as the size decreases. The size-dependence of shift could be explained very well in terms of excition fine-structure model and stress at interface owing to lattice mismatch contributes to the shift between CdSe and CdSe/ZnS with the same size.

结果显示表面修饰完善的样品的荧光光谱只有一个窄而强的带边发射；所有样品的荧光峰相对于1S-1S吸收峰有较大的红移，并且移动量随尺寸的减小而增加，利用激子的精细结构模型很好地解释了红移量和尺寸的关系；核／壳结构的样品的吸收峰和荧光峰相对于同尺寸的单量子点也有红移现象，这是由于CdSe和ZnS的晶格失配在界面上产生压力造成的。

Fancy gold-plated dangling earrings with facetted White Opal crystals.

花式镀金悬垂耳环与facetted白欧泊水晶。
