The spatial narrative structures in Calvino's fictions can be divided into three types :"the building of two worlds "is the main way in the earlier writing phase of Neorealist and Fairy tale .Dimidiation and mergence is the art feature .It signs that the sense of the world and the creative ideas of the writer start to form;"Synchrony and Juxtaposition "and "Crystal pattern "are the prominent characteristics during his Postmodernism writings phase. The writer takes the complex and diverse form of space art, such as segments、juxtaposition、defamiliarization、crystal's combination and derivatives, ect. to represent the essence of the world, and to exprsee the writer's confusion and efforts to understand and build a sense of it.

卡尔维诺小说的空间叙事结构具有阶段性，可以分为三种不同的类型：&两个世界的构建&是早期新现实主义和童话寓言创作阶段的主要方法，二分和弥合是其艺术特点，标志作家世界感和创作观念开始形成；&共时并置&和&晶体模式&则是后现代主义小说创作时期的突出特征，作家以片断、并置、陌生化、晶体组合衍生等复杂多样的空间化艺术形式来表现世界的本质以及自身理解世界、构建意义的困惑和努力。

Two-dimensional photonic crystal possess only pseudo photonic band gaps, so it is interesting and meaningful that whether the spontaneous emission of the atoms in two-dimensional photonic crystals can be controlled effectively.

二维光子晶体只有赝带隙，因此能否利用二维光子晶体有效控制原子自发辐射是令人感兴趣也是有实际意义的问题。

Of sodium erythorbate to white to yellow-white crystal powder granules or crystals, odorless, tasteless, melting point above 200 ℃ decomposition in dry conditions exposed in the air fairly stable.

异抗坏血酸钠为白色至黄白色晶体颗粒或晶体粉末，无嗅、无味，溶点200℃以上分解；在干燥状态下暴露在空气中相当稳定。

The crystal has a sheet structure with three-dimensional network, and can be regarded as"quasi-complete solvation"of 37 by DMF in the crystalline state.

该晶体为片状的三维网络结构，其形成可以被看作是在晶体状态下37分子被DMF&准完全溶剂化(quasi-complete)&的状态。

We can use the defect in the photonic crystal to guide the electromagnetic wave, and this photonic crystal with defect can be used to make photonic crystal devices.

利用光子晶体的缺陷可以实现引导电磁波的目的，可以制作各种各样性能优异的光子晶体光学器件。

The main properties of one-dimensional photonic band gap structures that include layers of negative refraction material are analyzed from the explicit dispersion equation. The results show that the photonic crystals containing negative refraction materials have wider photonic band gaps which is different from the case of traditional photonic crystals with narrow transmission bands when the two layers have the same optical thickness.

从色散关系出发，通过数值模拟计算研究了由正折射率材料和负折射率材料交替组成的一维光子晶体的能带结构与光子晶体的结构参数之间的关系。

The results show that though TiN and SiC monolayers exist as nanocrystal and amorphous respectively, the nanomultilayers grown by alternative depositing of TiN and SiC form columnar crystal with intensive preferred orientation.

结果表明，尽管TiN和SiC的单层膜分别以纳米晶态和非晶态存在，但由TiN和SiC通过交替沉积形成的纳米多层膜却能够生长成为晶体完整性良好的柱状晶并呈现强烈的择优取向，显示了一种异质材料晶体生长的相互促进作用。

Results show that when the thickness is less than 0.7 nm, Si3N4, normally amorphous in deposition state, could form a NaCl-type pseduocrystal structure due to the template effect of TiN crystal layer. Crystallized Si3N4 layers and TiN template layers grow coherently into columnar crystals with (111) preferred orientation. Correspondingly, the hardness of the films was enhanced to a maxim value of 38.5 GPa, showing a superhardness effect.

结果表明，在TiN调制层晶体结构的模板作用下，溅射态以非晶存在的Si3N4层在其厚度小于0.7 nm时被强制晶化为NaCl结构的赝晶体，多层膜形成共格外延生长的（111）择优取向超晶格柱状晶，并相应产生硬度显著升高的超硬效应，最高硬度达到38.5 GPa。

However the increase of subscribers asks for more efficient use of the limited spectrum resource. With the development of communication、navigation、radar、mobile communication、programmed telephone and measured instrument devices, the high performance of crystal oscillators is demanded.

随着晶体振荡器在通讯、导航、雷达、移动通讯、程控电话、测量仪表等电子设备中的应用，对晶体振荡器提出了更新、更高的要求，集中表现在频率稳定度高、调频范围宽、线性度优、功耗低、相位噪声低、成本更加低廉等方面。

It was found that gate voltage swing was 9V for MOS-HEMTs and 5.5V for MES-HFETs, respectively.

我们也发现到金氧半异质结构场效电晶体的闸极摆幅电压为9V，而金半异质结构场效电晶体则为5.5V。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
