Preparation of the cathode includes:shaping under the press of 40Mpa, sintering at 550℃for 1 hour and at 900℃for 8 hours and threading with molybdenum bar; Considering the literatures we choose CaCl2 as salt for preparation titanium. Pretreatment of salt is for 1 hour at 100℃and for 2 hours at 300℃. Partial pressure of oxygen which need lower than 5.11×10-7Pa to reduct titanium oxides and hygroscopic property of salt need a sealed equipment to electrolyse. And finally successfully designed a satisfied one and the results show that the equipment can be satisfied the requirment of the experiment. Flow of the inert gas is 1.5L/min, the voltage is 2.8 V, temperature is 850℃and time is 2 hours during pre-electrolysis. Flow of the inert gas is 0.2L/min, the voltage is 3.1 V, temperature is 900℃and time changes with the mass of TiO2 during electrolysis, namely the greater need the longer time; To eliminate influence of salt and other impurities, the products need to wash with distilled water and dilute chlorhydric acid , then wash with dilute hydrochloric acid under supersonic wave assistant. Finally, electrometical properties of the electrolysis of TiO2 is researched by cyclic voltammetry and chronoamperometry, and results show that there are two main reodox steps, namely from TiO2 to TiO and from TiO to Ti.

阴极制备主要包括40MPa压力下模压成型、两段式烧结(1小时内升至550℃保温1小时，再1小时升温至900℃保温8小时)及烧结后TiO2块打孔用钼棒串接三个主要环节；实验中选用CaCl2作为电解熔盐，并对其进行预处理(100℃，保温1小时； 300℃，保温2小时)；经热力学计算，还原钛氧化物的氧分压至少要低于5.11×10-7Pa，结合电解过程中所用熔盐CaCl2有极强的吸水性的特点，电解装置应有较高的密封性，自行设计了一套密封性可靠的电解装置，便于实验过程中熔盐预处理和氧分压的控制；通过干燥处理预电解过程中Ar流量大约为1.5L/min、电压为2.8 V、温度为850℃、时间为2小时，电解过程中Ar流量大约为0.2L/min、电压为3.1V、温度为900℃，实验结果表明电解时间与TiO2质量密切相关，质量越大需要电解的时间越长；通过自来水冲洗—稀盐酸浸泡、洗涤—在超声波辅助作用下稀盐酸洗涤，可减少熔盐及其它杂质对电解产物检测结果的影响；最后，通过循环伏安法、计时电流法对电解机理的研究，确定电解还原TiO2制备金属钛主要经历了TiO2-TiO-Ti的过程。

The strain gradient, the fiber Bragg grating's reflection and the short wavelength loss decide the two stopbands. Because of having no extra loss result from coupler and no high cost result from circuitor, the band pass filter formed by single chirped fiber grating have many good characters such as little insert loss its insert loss is the fiber splice loss, small volume, low cost and excellent property, moreover there is no report about fabricating filter by using this method, thus we will apply national invent paten about the method of fabrication fiber band pass filter using single chirped fiber grating. According to the parameters linearly chirped fiber gratings of Canada BRAGG Photonics Inc.

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.
