Combining the performance evaluation (activity, selectivity and stability) and the characterization of the catalysts (XRD, TPD, FTIR and the pore structure measure), it can be concluded that :(1)The activity of modified β is higher than MCM-22, but the selectivity of ethylbenzene is lower about 3% than that of MCM-22;(2)The mounts of diethylbenzene and the other by-products are higher 1.7 times and 1.5 times than these of MCM-22 respectively;(3)The catalytic performance of zeolite mixture is nearly equal to modified β, but the selectivity of ethylbenzene is higher about 0.5% than that of modified β;(4)The catalytic activity of zeolite is mainly correlated with the number of acid sites, strength and distribution, and the distribution of products is determined by the binding energy of ethylbenzene and the pore structure, while the stability of catalyst is affected by the amount of poly-ring aromatic alkylate and the pore structure.
以性能评价和特性表征(XRD、TPD、FTIR和孔结构测定)相结合的方式,对上述三种催化剂性能比较的结果表明:(1)改性的活性明显高于MCM-22,但乙苯选择性却低于MCM-22绝对差约3%;(2)改性(上二乙苯和其他副产物的生成量分别约为MCM-22上对应值的1.7和1.5倍左右;(3)混合型催化剂的性能与改性相仿,但乙苯选择性提高0.5%左右;(4)对乙苯合成,沸石催化剂的活性主要取决于其B酸中心数、酸强度及酸分布,产物分布则取决于催化剂表面的乙苯脱附能垒值和孔道结构,而稠环芳烃的生成量和催化剂孔道结构是影响催化剂稳定性的主要因素。

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.

In the incontinuous cutting, the wave shape of milling can be looked as periodic function. When the milling wave shape with single-tooth was looked as impulse function, by the Fourier Transform, we can find out that it is composed of sine wave with a given frequency and a series of integer multiple frequency. Discussing on the power function is a major tache for studying on the cutting capability of the complex three-dimension groove milling inserts, so to know the facts that affect the single-tooth milling spectral value, and to observe the dynamic milling wave property from the composition of the power spectral, thus we can design and optimize grooves.

This kind of gratings can be kept in the material for a long time. A mode of molecular reorientation was used to explain the formation mechanism of these gratings and it is well consistent with our experimental results. 3. Three kinds of azobenzene polymers P , P (MMA-co-GY7) and P (MMA-co-GO13) were synthesized by radical polymerization. High-density optical storage and the three-dimension (3D) microstructures in the azobenzene polymer films were presented. Twenty gratings have been stored on the same spot in our material. It is twice as many as the best recording that has been reported. It is the first time, a rectangular microstructure and a complicated double layers nesting six-pointed star microstructure are inscribed in it by using a simple two-wave couple setup.

A usual starting dose of 10 mg given three or four times daily increasing if necessary to a maximum of 20 mg given five times daily has been used. 2 However, some workers have recommended limiting the dose to 80 mg daily because of the increased risk of seizures with higher doses. 3 Adverse effects appear to be mainly mild and dose related, 1 although there is a report of cardiac arrest following toxicity. 4 Most patients have some form of paraesthesia up to 60 minutes after a dose. 1-3 Amifampridine can produce mild excitatory effects and some patients may have difficulty in sleeping.

It took Cockcroft and Walton five years to build a machine that worked. Finally, in April 1932, they had a machine that produced a steady stream of hydrogen nuclei with an energy of about half a million volts. They were carefully measuring the quality of the stream, in no hurry to begin doing nuclear experiments. On the morning of April 13, Rutherford came into their room, saw what they were doing, and lost his temper. He told them to stop wasting their time and do some science. The next day, Cockcroft was occupied with other business. Walton was alone in the laboratory, ready to do the first experiment, using his hydrogen nuclei to bombard a target made of the light metal lithium. The result was spectacular. The lithium nuclei were split in two and fell apart into pairs of helium nuclei.
