进一步，我们引入了部分对称正解的概念，并讨论了二阶泛函微分方程边值问题的三个部分对称正解的存在性。

The nonlinear dynamic equations including the initial geometric imperfections of laminated composite cylindrical shells were derived from Hamilton's philosophy. Assuming the transverse displacements to be composed of axially symmetrical part and axially asymmetrical part, the governing equations expressed as displacement forms of dynamic buckling were obtained by Galerkin method. The equations were solved by finite difference method. The effects of impact velocity, lamination angle, initial geometric imperfection on the axial dynamic buckling of laminated composite cylindrical shells were discussed.

Moreover, this dissertation reveals an essential conclusion: The existence of the state feedback solution of H〓 problem is equivalent to that of the maximinimizing the LQ problem, by the existence of real symmetric stable solution of GARE.

文中从微分Riccati方程解的存在性及其性质的论证出发，最终得到了GARE实对称解存在条件的结论。在§2-4中，揭示了本文研究的maxmin鲁棒最优控制问题与H∞状态反馈解及GARE实对称解的存在性等价这一实质性结论。

On the basis of Gaskell′s calender theories,it was set up that the mathematics model of the symmetrical calender processing of Newtonian fluid and that of non－newto nian fluid which was looked on as pure v iscous power－law fluid.It also included the content of rolls deformation and com pensation complied with mechanical calcu lation.

本研 究主要根据Gaskell理论建立了牛顿流体对称过程的压延流变数学模型、非牛顿流体对称过程的压延流变数学模型；还根据机械计算方法建立了压延辊筒变形的计算及补偿方法的数学模型。

If the fingers are asymmetric than that means that the person has a creative, artistic character but if there are very symmetric with each other, that means the person is the hunter and gatherer type, created for business life.

如果手指不对称，说明他有创造力，艺术家的性格；如果手指对称，意味著他是猎人或采猎者型，即为事业而生的人。

Dynamic numerical analyses to geometrically symmetric and asymmetric samples are carried out with ANSYS software.

用ANSYS软件对几何对称试件及非对称试件进行了动态数值分析。

The linear dependence of all limb constraints can be judged geometrically and the properties of mobility can be obtained.

笔者提出的方法不仅适用于对称少自由度并联机构，也适用于非对称少自由度并联机构。

The matrix filter generating the GHM (constructed by Geronimo, Hardin, and Massopust) is not symmetric, so GHM can not solve the edge problem accurately in image coding.

生成CL二重对称小波的正交矩阵滤波器虽然对称，但构造方法缺乏一般性，因此论文对此作了进一步的研究。

Through establishing the business enterprise trustworthiness with the gene ral model of game and the model of the repeated game,this text discuss es the be havior of business enterprise in the term of dissymmetry information,and gets a conclusion that the business ent...

出现这一矛盾的根源，在于信息的不对称分布，本文通过建立企业诚信的一般博弈模型和重复博弈模型，讨论不对称信息环境下企业的行为选择，得出企业追求长期利益会导致诚信的结论。

The optimal model of hedging based on the partial moments reflects the asymmetric attitudes on the loss and gain of the hedger.The model changes the phenomenon of the present research assumption that attitudes on the loss and gain of the hedger is symmetry.

偏矩套期保值优化模型反映了套保者对赢得和损失的非对称态度，改变了现有研究大多认为套保者对赢得和损失的态度是对称的不合理的现状。
