It is convenient for sinter to be leached, and the secondary reaction appears little. The slurry after sinter leaching is transferred into autoclave for desilicification at about 170℃, and the siliceous modulus of solution reaches more than 200. Then some lime is added for deep-desilication at normal pressure, the siliceous modulus of solution increases more than 600 even if the Al2O3 content is more than 200g/L.The SiO2 coefficient in hydrate garnet from deep-desilication is more than 0.28. Under conditions of the addition of seed and application of novel technology of carbonization, the contents of Na2O and SiO2 in product are less than 0.37% and 0.025%, respectively.

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.

The second part makes an innovative study of the soul of traditional Chinese graphics in the respect of "shape","essence", and "implication". The first element to be emphasized is "shape", which is mainly concerned with lineal designs and convolute designs in traditional graphics, the main two ethical factors employed in traditional Chinese design. The "shape" is a relatively complete and minute system. What is included in "essence" is to convey the effect of lucency and artistic conception in traditional plastic art, which embodies traditional Chinese philosophy and its aesthetic taste. The "implication" part makes a detailed analysis of the informative function of the particular ethical graphics from the perspective of disseminative theory. The third part is my application of the three elements in designing.
