Using numerical simulation technology and method of orthogonal experiment design and single factor rotating optimization, this thesis makes a study of "lost core injection ", thus achieve the optimization of the parameters of molding process, to offer basic reference when developing production technology and mould of the plastics intake manifold. Based on the study of the status in quo and development trend of weight reduction on automobile, the application of plastics to automobile and intake manifold, then under the guidance of theory model and numerical simulation technology in the process of high polymer material, this thesis launches flowing main research work: First of all, on the basis of the three-dimensional model of the part and finite element net model, several designs of gating and running system are numerically simulated and analyzed via MPA of Moldflow.

本文在对当今汽车轻量化、零部件塑料化以及的汽车进气歧管塑料化的发展现状和发展趋势进行了研究和简要介绍，然后在高分子材料成型过程中的理论模型和数值计算方法的指导下，展开主要的研究工作：首先，在零件三维模型和有限元网格模型的基础上，使用Moldflow 的MPA模块对塑料进气歧管的多个浇注系统设计方案进行数值模拟，通过分析各个方案的充填质量、熔接线位置及数量等指标，得到了综合质量较高的4 个进料口的浇口位置及半限制型浇口大小的浇注系统。

The crystal-lization of this amorphous alloy is a multi-stage continuous nucleation up to saturation process. The local crystallization energy decreases gradually indicating that the thermal stability of the residual amorphous matrix becomes weak at the steady crystallization stage, which is ascribed to the diffusion of boron atoms at elevated temperatures.

进一步研究发现，该非晶合金的晶化为多阶段的连续形核直至饱和的过程；当进入稳定晶化阶段时，剩余非晶的局域晶化激活能逐渐下降，非晶基体的热稳定性降低，这是由B原子的高温扩散导致的。

The experimental results revealed that papain, calcium chloride, compound phosphate, and glucide keeping humidity reagents intensify the tenderness of pork jerky, but the addition should be proper. The best proportion was papain0.4‰, compound phosphate 0.4%, calcium chloride 0.1%, and sorbitol 1.5%.

实验结果表明：木瓜蛋白酶、复合多聚磷酸盐、氯化钙和糖类保湿剂都可增加肉脯的嫩度，但用量应适当，添加量过大，反而使肉脯的感官品质变差；肉脯嫩化的最佳配比为木瓜蛋白酶0.4‰、复合多聚磷酸盐0.4%、氯化钙0.1%、山梨糖醇1.5%。

In this thesis, we focus on the minimization of the switch activity for each 2-to-1 MUXes in the MUX tree.

在此论文里，我们针对在多工器树里面的每一个2对1多工器的交换频率做最小化的处理。

As our studies showed, silylation of mesoporous molecular sieves with alkoxysilane was an usual method of linking desired organical groups. However, as a result, the a lot of silanol groups still existed on the surface of mosoporous molecular sieves after silylation, which maybe affect the interface property and its catalystic activity. Based on this consideration, a novel method was proposed that a mixture of trichlorosilanes was used to silylate mesoporous molecular sieves, introducing both the further reactive group and hyhrophobic methyl group in one pot.

正如研究表明，通过硅氧烷与介孔分子筛表面的硅羟基反应是常见的键连有机基团的方法，但表面仍会剩余较多的硅羟基，硅羟基的存在会严重影响到介孔分子筛表面性质及催化活性，为此笔者提出采用混合的三氯化硅烷一步硅烷化介孔分子筛，在孔道内同时引入可进一步功能化的氯丙基或氯苄基和疏水性的甲基。

Dunhuang populace have no longer limited to the national -- countryideology in unified dynasty time under the historical background that centralauthorities estranging from Dunhuang day by day,Guiyi Army being graduallyindependent and region religion and ethnic groups\' historical restructuring.Ethnicgroups of Dunhuang have progressively integrated into a community which was amulti-ethnic,multi-religious culture region through each other\' s marriage,language,custom belief and so on.The social groups have changed opposition eachother and sought the internal approval.

在中原王朝与敦煌地方日益疏远、归义军政权渐趋独立化、敦煌区域宗教与族群经历了历史重构的背景下，敦煌民众也不再局限于统一王朝时期的民族——国家的意识形态之中；各族群通过婚姻、语言、习俗信仰等多层面的交流与融合，已日渐聚合为一个融汇有多民族、多宗教文化的区域利益共同体，社会群体一改过去的彼此对立，努力寻求内部认同，显然是有效维护各个族群共同生存的地域利益与群体利益的必由之路。

Foregrounding theory does play a very important role in calling people's attention to the medium of language itself, but it must be kept in mind that this theory is never a panacea of universal value.

前景化理论在唤起人们关注语言媒介本身方面功不可没，但是，应该注意的是前景化理论并非是一种普适的万能理论，它仅仅是提供了一种观察和认知世界的方式，文学翻译的研究必须借助各种视角，才能实现对它的多维度的认识。

At present,information technology is rapidly developing to high integrated and complex direction, more and more microchip components have been integrated on one substrate. In order to minish the volume and weight of the system, one-way is to develop the micro-integrated technology, and another one depends on miniaturizing the components.

目前IT系统向高集成度、高频宽带化方向发展，要求在更小的基片上集成更多的元器件，这除了依靠高密度集成技术的发展外，从器件本身出发，只有研制小型化、薄膜化的器件，以减小系统的整体体积、重量，才能达到减小功率损耗、提高信号传输效率的要求。
