三比二

By the 1920s, Chanel's designs were very well-received, so much so that she opened two boutiques: one in Paris and one in Biarritz. These ships employed more than 300 people in a time when jobs were scarce.

到了二十世纪二十年代，香奈儿的设计大受欢迎，她分别在巴黎和比亚里茨开了两家时尚店，员工超过三百人，在那个经济萧条、失业剧增的年代，这是相当可观的。

The results showed that there were three minimum values in the second derivative spectrums of normal person, in contrast there were four minimum values in most diabetic second derivative spectrums, the diabetic urine had one minimum value more than normal urine during the range from 550 nm to 570 nm.

发现健康人的二阶导数光谱都有三个极小值，与之形成对比的是绝大多数糖尿病患者的二阶导数光谱却有四个极小值，糖尿病患者的尿样在550 nm～570 nm区间范围内比健康人多出一个极小值。

Secondly, we provide a two-level model to depict the one-, two-and three-photon fluorescent process and with it to calculate the one-, two-and three-photon fluorescence intensity dependence of the incident excitation intensity and time. We study the fluorescence intensity when excitation light's time distribution are square pulse、Gaussian pulse and sech pulse. We find that the influence of excitation light's time distribution on the two- and three- photon fluorescence peak intensity is larger than the one-photon fluorescence peak intensity. Two-level model can account for the behavior of saturation fluorescence.

然后用二能级模型解释了单、双、三光子激发原理，在理论上推导出了单、双、三光子吸收诱导荧光强度与脉冲强度以及脉冲作用时间的关系，并进一步研究了入射光时间分布分别为矩形、高斯型、双曲正割型时激发溶解在氯仿溶液中的C22H22N4O样品所产生的荧光峰值光强，结果表明激发光的时间分布对双、三光子荧光峰值强度的影响比对单光子的影响要大。

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.

Along with big three arrivalses, I also will continuously favour, on the other hand, Be college of study department minister, again just right meet with an undergraduate course valuation, in spite of to who is all kind of pressure, besides is the teaching of the Ministry of Education valuation, that still is not my head up, school begins two month estimate favour dead, attended Normal University television station in Fukien on the other hand, participate television station of work, do film, return have what than the consume more of, again remove have a class of time, I estimate I possibility also have no when, luckily big three since need not learn English also need not learn athletics, easy is easy not a few, but face profession of thorough mental state more or less also have some touch, particularly is more and more of person all seem to have oneself of direction, but I seem to seem big two just just started grope for similar, we the class believe to will haven't a few violent girl and boy devotion to test to grind battalion, everyone also more and more went by different roads, believe big three big four ～ss~～ the person be more and more fickleness, ha ha.

随著大三的到来，我也将陆续忙起来，一方面，作为学院的学习部部长，又刚好碰上本科评估，不论对谁都是一种压力，何况是教育部的教学评估，那还不就是我的头上，开学两个月估计得忙死，另一方面，参加了福建师范大学电视台，要参与电视台的工作，做片子，还有什麼比这个更耗时的呢，再除去上课的时间，我估计我可能也没有什麼时间了，幸好大三既不用学英语也不用学体育，轻松是轻松了不少，但面对专业的深入心理多多少少也是有一点触动的，尤其是越来越多的人都似乎有了自己的方向，而我似乎好像大二才刚刚开始摸索一样，我们班相信会有不少强悍的女生和男生投入考研大军，大家也就越来越分道扬镳了，相信大三大四～~～人是越来越浮躁的，呵呵。
