本文得出结论：严重的信息不对称是造成中国个别股票价格被操纵的最主要原因；信息不对称容易产生知情交易和噪声交易；中国股票市场还未达到弱有效率；中小投资者和政府成为信息不对称的受害者。

Based on Stahl (1988), this paper extends symmetric model in duopoly in Spulber (2002), analyzes the asymmetric model of competition with both different inputs and outputs, and examines in detail the impact of differential parameter of supply and demand on competition.

本文以Stahl(1988)为基础，将斯普尔伯(2002)对称的双寡头垄断中间化对称模型进行扩展，分析了投入品与产出品都不同的非对称寡头竞争模型，并详细考察了供给、需求差异化参数对竞争的影响。

The result of simulation can provide reference to antenna designing. A method is given to compensate the dissymmetry.

分析了天线幅度、相位不对称对测量角误差的影响性质，可为提出天线设计的对称精度要求提供参考，并提出了天线幅度、相位不对称的补偿方法。

The application of the method can also be extended for the textured materials with other sample symmetries in addition to orthorhombic symmetry.

所述方法可适用于任何晶体结构对称的织构材料及三维应力状态，并可推广至正交对称外的其他试样对称的织构材料。

Our main work is as follows: the stable laser mode theory in uniform plasmas is extended to non-uniform plasma cases; the discussion of the sufficient and necessary conditions for laser self-focusing in uniform plasmas is developed to non-uniform plasma cases; a quantitative approach to judge the impact of different plasma density distribution on laser self-focusing is proposed; the evolution properties of asymmetric laser filed in non-uniform and uniform plasmas are discussed and mechanisms that symmetric channel-like plasmas can confine the laser centroid around the plasma channel axes and symmetrize initially asymmetric laser beams are proposed; the formation of solitary standing wave in moderate plasma density is studied by PIC simulations and can be explained by stimulated Raman scattering of laser beams in plasmas.

主要工作为：把均匀等离子体中激光的稳定模理论推广到横向非均匀等离子体情形；把均匀等离子体中激光自聚焦的充分和必要条件的讨论推广到横向非均匀等离子体情形；给出横向密度分布不同的等离子体影响激光自聚焦的定量判据。讨论了初始不对称的激光场在横向非均匀及均匀等离子体中的演化特性，并提出了具有对称腔道结构的等离子体箍缩激光质心和对称化初始不对称激光场的物理机制。用粒子模拟讨论了激光场在等离子体中形成孤立驻波的过程，认为前向受激拉曼散射是发生此现象的可能机制。

But according to principle of relativity and absolutization theory, the effort of super symmetry has no end, super symmetry demands the existence of gravity-微子 with spin 2/3 except gravity-quantum.

但是根据对称的相对性与绝对性原理，超对称的工作是没有止境的。超对称要求除引力子外，还应当有自旋3/2的引力微子存在，但是实验上并没有发现它的存在。

Background : Individuals with hemiparesis frequently shift most of their body weight to uninvolved side, showing a obviously asymmetry of standing posture and weight bearing pattern. Postural asymmetry places the individual with hemiparesis at a greater risk for falls. Asymmetry weight bearing contributes to gait abnormalities.

研究背景：半边麻痹的中风患者时常会把身体的重量放在好边的脚上，让好脚去承载身体大部分的重量，因而产生明显不对称的站立姿势和两脚不对称的重量承载比例，姿势的不对称会致使患者跌倒的危险性更大，重量承载的不对称会致使患者走路时有不正常的步态。

In part two, the empirical results indicate that the predictive ability of SGT is much better than GT、ST、t and Normal distribution. SGT can correct not only fat-tailed property, but also defects the low kurtosis of GT and t distribution. For the volatility of asset return setting, the assumption of volatility of assets price is more appropriate than Normal and asymmetric distribution which was often used.

第二部分以实证结果显示偏态一般化t分配的配适能力较一般化t分配、偏态t分配、对称t分配和常态分配为佳，亦即当金融资产报酬率存在高峰态与厚尾现象时，偏态一般化t分配不仅可以解决常态分配所无法捕捉到的厚尾现象，亦可修正一般化t分配与对称t分配无偏态的缺点，对於资产报酬率波动性之设定，比过去常使用的常态分配与对称的分配更为适当。

This With the status quo of China's real estate market information asymmetry on the type of real estate information asymmetry, causes, hazards analysis, and how to improve the information asymmetries put forward countermeasures and suggestions.

本文结合我国房地产市场信息不对称现状，对房地产业的信息不对称的类型、成因、危害进行了分析，并对如何改善信息不对称现象提出了对策和建议。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
