A grating function and a groove function are introduced to determine the structure of a concave grating. Basic ideas for the design of a flat-field concave grating with three stigmatic points are proposed. As a proof of the usefulness of these design approaches, image conditions of the grating with three stigmatic points are developed which concise with other published results and they are more general than those obtained from holographic gratings.
采用与分析三维光栅相类似的级数展开法给出了二维集成凹面光栅的球差、彗差的计算方法,计算中用光栅函数和槽面函数来描述具有任意形状和任意变化周期的光栅,提出了一种具有三个无像差点的平面场型凹面光栅的设计方法,利用该方法推导了三点无像差光栅的成像条件,与文献中用其它方法获得的结果相一致,该结果与全息光栅的成像条件相比,更具一般性。

So when we felt another kind of tetra-dimensional, extreme, music-like art made up of colors and lines in Malevich and Tatlin's experiment in the early of last century, people had to get used to the visional format from Kandinsky, Pollock, Mondrian and Roscoe. The brand-new artistic experiment is further rooted into experience of our religion, music, philosophy, life and other staffs not only from format to content, but also from theory to techniques. And the traditional plane paintings are used to annotate the art meaning of non-representation. But Chinese are unwilling. It is only the format product of powerful culture in expanding, rather that there are lots of differences between the western abstract and oriental "image".
所以当我们从上个世纪初在马列维奇、塔特林的实验中,体验到一种被称为四度的、极致的、音乐似的、或者说将色彩和线编制成为另一种艺术自由的端倪时,人们就不得不习惯由康定斯基、波洛克、蒙德里安和罗斯科所带给我们的视觉图式,它们从形式到内容、从理论到技巧,无不变本加厉地把这种全新的艺术实验根植于我们对宗教、音乐、哲学、生活以及诸多问题的体验中,并用传统的二维平面绘画来诠释出非具象的艺术意义,不过这些对中国人来说,很可能是不情愿的,它只是强势文化在扩张中的样式产物,更何况这些西方式的抽象与东方式的"意象"仍然有着极大的差异。

The thickness of the ice cover on the wall surface heat transfer is greater than the thickness of it on the air heat transfer form. The thickness of the ice cover on the wall surface heat transfer along the way changes slowly, but it on the air heat transfer along the way changes significantly. Reducing the entrance velocity, lowering the wall surface or air temperature, the formation of the thickness of the ice cover will increase; in the 3D circumstances, The thickness of the ice cover was relatively uniform in the import of the U-turn model, the ice cover was gradual accumulation in the convex bank when the stream traversed the import of the U-turn model, the thickness of the ice cover in the convex bank was significantly bigger than the thickness in the concave bank. The temperature field under the ice cover tends to be complex because of the existence of the secondary flows. The temperature in the convex bank is greater than it in the concave bank. Compared with the data from experiments, the laws in the numerical simulation are similar with them in the experiments
模拟结果显示:二维情况下,运用壁面传热形成的冰盖厚度大于运用空气传热形成的冰盖厚度,壁面传热形成的冰盖厚度沿程变化缓慢,而空气传热形成的冰盖厚度沿程变化明显,减小入口流速,降低壁面或空气温度等,形成冰盖的厚度都会增大;三维情况下,弯道入口处凸、凹岸形成的冰盖厚度基本相同,进入弯道后,凸岸形成的冰盖厚度逐渐增大,而凹岸的冰盖厚度逐渐减小,受横向环流的影响,冰盖下水流的温度场趋向复杂,并且凸岸的温度小于凹岸的温度;与实验室实验所得数据相比较,数值模拟研究得到的规律基本符合实验规律。

It is time-consuming. The dissertation basis the laser scan data organization form of two dimension grids, the three-dimensional point directly relation to vicinage region point, the new corresponding point will produce from the neighbor region.
本文根据激光扫描数据二维网格的组织形式,三维点的邻域关系直接体现在距离图像象素点的邻域关系上,因此对应点周围的点也有可能产生新的对应点,所以采用在已知对应点的邻域内局部搜索新的最近的点对,提高搜索的效率。

In the same time, water-soluble bidental phosphines ligand BISBIS sulfonated 2,2''-bis(diphenylphosphinomethyl-1,1''-biphenyl was synthesized, and water-soluble rhodium complex Cl was synthesized in situ. This complex which was used as catalysts to catalyze the hydrogenation of avermectin was also tested. Although the rhodium complex containing bidentate phosphine BISBIS showed a higher catalytic activity than one containing TPPDS, the selectivity for ivermectin was lower. How to improve the selectivity will be needed to studied in futur.

Furthermore, the one-dimensional complexes 26 and 28 with strongπ-πpacking interactions are prepared from DMF solvent, which indicates that the traditional solvent volatilizing method could bring low-dimensional complex.4. By measuring the enthalpy changes of the liquid phase formation reaction for complexes a~e, and calculating the electronic densities of five 5-substituted derivation of isophthalic acid, we can make a conclusion that 5-substituted group changing of the ligand has a little influence on oxygen atoms of carboxyl groups.5. Fluorescence experiments of these complexes indicated that they could be used for luminescence materials in future.6. Using packing saturation rule we calculated and analyzed these series of complexes, and the results showed that the changes of complexes with changes of ligands could be explained from the rule.

In this study, isobaric tags for relative and absolute quantification labeling coupled with two-dimensional liquid chromatography-tandem mass spectrometry (2D-LC-MS/MS) was employed to compare the differential protein expressions in MCF7 cells upon 17β-oestradiol (E2) stimulation or serum deprivation versus in normal conditions. A total of 576 proteins with the confidential level of ≥95% were identified, 26 proteins among the 576 proteins were found to be differentially expressed after E2 stimulation or serum deprivation, and among them 10 proteins were up-regulated and 16 proteins were down-regulated by more than two folds.
