Further reflective type measurement can be implemented by THz-TDS. Interface information is obtained from the measured THz waveform reflected from stacked burned and normal porcine skins for simulating partial burned skin. Reflective wave from surface, interface between burned and unburned, back surface of unburned porcine had been correctively and clearly observed. Waveform and time of flight matched well with the original reflected waveform of normal and burned porcine skin.

WE move into tall apartment buildings and don't bother to find out who our neighbors are for the last ten years. Thanks to telephones and internet, we've withdrawn form our desires to visit friends and we can no longer received hand-written letters ---maybe leaving a more hurmane China for the hightly modemized West has exposed Liu Ming more to the inner lonesomeness and remoteness among human beings. But we need not necessarily regard the deadpan buildings. Vacant basketball hoops and deserted basketball courts as an image of the mournful, lonesome and remoteness among human beings. But we need not necessarily regard th edeadpan buildings.

所以，在他的作品中，楼房、篮球场和其他物体一律处理成没有任何生气的在灰色，而且排斥任何的笔触、绘画性和形式感，以避免给画面带来丝毫的热情，而且，其中最重要的语言因素是，在他完成画面的绘制过程后，他使用丝网滚子在整个画面上罩上一层薄薄的单色，使这个静物般的城市，在人们的眼中象"雾里看花"，象隔着一层类似塑料薄膜一般的屏障，失去了一种亲切感，这就是我说的"距离感"——人的生存环境同时成为与人有距离感的环境。

At the temperature as low as that at which the monomer cannot diffuse in large scale,adatom nucleation and island formation depends on the increase of adatom density.With the increase of temperature,the film growth mode depends on the competition between in-plane diffusion and inter-layer diffusion of monomers.

当薄膜生长温度低于单原子的扩散温度时，表面原子的成核和表面岛的生长主要是由沉积原子的空间随机性和表面原子密度增加而决定的，随着薄膜生长温度的提高，薄膜的生长模式则取决于单原子的层内扩散和层间扩散的竞争。

Both crystallographically unique Zn atoms exit as an octahedral geometry. The four equatorial positions of Zn1 atom are occupied by the carboxylate-oxygen atoms of the two tartrates, and the two oxygens of the left four carboxylate-oxygen atoms coordinate to two different Zn2 atoms, respectively, forming infinite coordination polymer chains. The left two of the trans equatorial positions of Zn2 atom are completed with two oxygen atoms of two water molecules.

The UV and IR spectroscopic studies of the monomer films showed that the photoreaction ratio of monomer (about 50%) was higher than the corresponding photosensitive polymer (about 10%, PVCi). The polarized IR spectra proved that obvious anisotropic absorption was displayed in the irradiated photosensitive film. With polarizing microscopy method, we found that these kinds of photoalignment films exhibited good alignment ability, and the stability of the photoalignment film could reach about 100℃. 2 A photosensitive self-assembled monolayer was fabricated that contained photo-cycloadditable groups, such as, coumarin and cinnamate. The reaction process were detected by contact angle method because the IR absorption of monolayer was very weak. The photosensitive self-assembled monolayer promote uniform alignment of nematic liquid crystals by LPUV, and it thermal stability could reach about 130℃. 3 A cationic bolaform amphiphiles was synthesized that had two photosensitive double bonds, and can be polymerized by ultraviolet. A layer-by-layer self-assembled deposition film was prepared in aqueous solution by using this material and poly (sodium 4-styrenesulfonate). The UV-Vis. spectra proved that the multilayers film was uniform and layer-by-layer. When LPUV irradiated the film, the photopolymerizable double bond underwent [2+2] cycloaddition, and the production of the reaction distributed along the polarized direction of incident LPUV. Polarized UV-Vis. spectra indicated that the irradiated self-assembled multiplayer film was anisotropic, and the dichromic ration is about 0.09, it is higher than the spin-coating method of photosensitive polymer or monomer. We used this anisotropic film as alignment layer of nematic liquid crystals, and obtained a uniform and stability alignment result, the static contrast ratio is about 100, which is very close to application of liquid crystal device. This thesis is an instance that the photochemical material was used in the physics region of liquid crystals, the route that was from photosensitive monomer, self-assembled monolayer film to self-assembled multiplayer film was undergone, by this logical research method photoailgnment of liquid crystal was extended and consummated.

从G IS数据库中挖掘空间关联规则的主要问题是多层、多关系的规则挖掘问题，不同专题图层不同空间对象之间空间谓词的高效计算与存储表达是解决问题的关键；把空间关系非空间化，将连续数据离散化，从而把求解问题转换成布尔型关联规则问题进行讨论，基于此而探讨了一种通过SJI-P表组织空间谓词，然后根据目标对象的概念层级自顶向下、逐层细化的空间关联规则挖掘方法。

First odd: This song if from a distance look like a large potted plant, to observe from different angles, its appearance is very different, such as from north to south of view, the outline of the tree, and are growing, with the mountains in front of attached Masan contour toward exactly the same, identical, more particularly strange is that this tree structured patchwork of divided into four floors up and down, instead of the corresponding attached Masan accordingly divided into four floors up and down the mountains and trees echoed accordingly into the fun.
