We first introduce the state of the art of Web Services Composition, and then analyze the relation between Web Service Composition and related theoretical backgrounds. Concerning the two key technologies, service composition method and service composition system, we demonstrate our work.1.

The acidic composition can be prepared by mixing a monovalent or polyvalent cation and an organic acid in the presence of a strong oxyacid, wherein the resultant acidic composition is less corrosive to a ferrous metal than a solution of a mineral acid having the same acidic pH value as that of the acidic composition, and where in the acid composition is more biocidal than a mixture of the organic acid and a metal salt of the organic acid which mixture has the same acid normality value as that of the acidic composition.

所述酸性组合物可以在一种强羟基酸存在时，通过混合单价或多价阳离子和有机酸来制备，其中与具有相同的酸性pH值的无机酸溶液相比，所形成的酸性组合物对含铁金属的腐蚀性更小，并且与具有相同酸当量值的有机酸与有机酸金属盐的混合物相比，所述的酸组合物具有更强的杀生物作用。

The result indicated:Without considering the influence of atmospheric turbulence,the visibility is higher,the beam intensity attenuation is smaller;Under the condition that only considered the atmospheric turbulence influence,wave length of transmission laser and refractive index of atmospheric structure constant have an important influence on beam intensity distribution.

结果表明：在不考虑大气湍流影响的条件下，能见度越高，光强衰减越小；在只考虑大气湍流影响的条件下，传输激光的波长，大气折射率结构常数，对激光远场光强分布具有重要影响。

Some conclusions are inducted through the study: first, grid nudging with the rountine observed data in the MM5 simulation of atmospheric duct affects less over the sea than the land;Second,how much of sigma levels have great influence on simulation of atmospheric duct and the MM5 simulation with more sigma levels depicting the atmospheric ducts are reasonable; Last, multiple nests are allowed on a given level of nesting domain in the MM5 model.

通过研究得到了以下结论：(1)利用常规资料进行格点同化对海上大气波导影响较小，对陆地影响较大；(2)垂直分层对大气波导特征参数影响明显，层数较多描述大气波导比较合适；(3)对于海上大气波导，细网格刻画大气波导特征参数比较细致，但粗网格的模拟已经足够进行大气波导分析。

The first is termed aero-optic and involved optical transmission through aberrating fluid layer whose thickness, L, is smaller than or comparable with the viewing aperture dimension, A, and the turbulence scales, A , are smaller than or the order as the layers thickness:The second category, atmospheric propagation, involved optical transmission through the aberrating medium over very long propagation distance compare with the viewing aperture size, and the turbulent scales of note are generally less than or the same order as the propagation distance:Depending on the atmospheric conditions, for ground-based observatories, wave-front sensor operating at 300HZ can adequately resolved both the important spatial scales and the temporal evolution of the atmospheric-turbulence-induced aberrating wave front over viewing aperture associated with relatively large telescope.

第一类问题光学畸变发生在&近场&较短的光路上，即流层厚度L，光束直径A，以及湍流尺度Λ三者之间存在关系式：ΛA≤L≤A第二类大气传输问题光学畸变则发生在较长的一段光路上，L，A，以及Λ满足： A＜＜Λ≤L对于地基情况下的大气光学传输，300Hz的波前传感器就能实时地测得光波前畸变包括时间、空间频率的相关信息，为我们的自适应光学系统的设计、制造以及进行相关的自适应校正都有着相当重要的指导意义。

The experiments for determining the reaction kinetics of Daqing atmospheric residue were performed in a continuous flow, expanded bed rector. Four-lumped reaction kinetic model was developed to account for various feed and product fractions of Daqing atmospheric residue (gases, gas oil, residue and coke). The amounts of olefins and alkyls in the gas products were further analyzed to determine reaction kinetics of gas product distributions. Hence, a combined five-lumped reaction kinetic model was obtained for catalytic pyrolysis of Daqing atmospheric residue. The kinetic constants both in four-lump model and five-lump model were evaluated. A simulator for catalytic pyrolysis process was developed by incorporating the five-lumped kinetic model into the hydrodynamic flow model.
