In the long term, China's national interests in developing bilateral relations lie in three aspects: firstly, to further consolidate security trust and extend security cooperation between the two nations, It will guarantee long-term stability for China's northern frontiers; secondly, in the process of social transformation, both can learn from each other, adhere to democracy and law with their own characteristics, further advocate diversity of world civilization, and promote a multipolar world; thirdly, both can make hest use of economic complementarities between them to map out common strategy, strive for common develop, and realize common prosperity.

在未来很长的历史时段里，中俄关系中的中国国家利益在于：进一步巩固中俄两国的安全信任，拓展中俄两国的安全合作，确保中国北疆的长治久安；在社会转型的过程中与俄相互学习、相互借鉴，坚持走有本国特色的民主、法治之路，进一步倡导世界文明的"多样性"，推动世界格局的"多极化"；最大限度地利用中俄两国的经济互补性，制订共同战略，争取共同发展，实现共同繁荣。

In order to reasonably depict four basic problems with friction, one Coulomb friction new form in first Kirchhoff stress is proposed to deal with finite deformation problems, other Coulomb friction form in incremental mode to elastoplastic flow theory; Hilbert function spaces concerning elastoplastical problems with friction are established, so it makes all operations and calculations in the treatise standardized within the scope of reasonably topologic structure; In view of functional extremum, the equivalence between generalized variational inequalities principles in elastoplasticity with friction and corresponding basic problems are testified by inducing Lagrangian multipliers, so it provides a rationally theoretical basis for numerical methods in elastoplasticity with friction; From the viewpoint of variational inequality, the theory of generalized variational inequalities in elasticity and elastoplasticity with frictional constraint is studied, and the uniqueness and existence of the solution of FEM is proofed under the proposed conditions of stress compatibility, and them FEM approximation and a discrete solution are discussed; Based on the principles of generalized variational inequalities in elastoplasticity with friction, direct generalized variational inequalities methods is pretended, which is a natural generalization and development of direct variational methods; Using generalized variational inequalities methods, some examples in metal forming including plane deformation, upset and extrusion are analyzed and the results prove that all the theories and methods in the paper are right, feasible, accurate and advanced.

主要内容有：为了合理地描述金属塑性成形中摩擦约束弹性、弹塑性基本问题，提出和研究了有限变形下以Kirchhoff第一应力表示的Coulomb摩擦定律形式和弹塑性流动理论下以增量形式表示的Coulomb摩擦定律表示形式；系统建立了摩擦约束弹塑性问题的Hilbert函数空间，使本文规范在一个具有合理的代数拓扑结构内进行一切操作和运算；利用Lagrange乘子，从泛函极值的角度系统地阐述和论证了一系列摩擦约束弹性、弹塑性广义变分不等原理与相应的实际问题之间的等价性，它为处理摩擦约束的弹塑性力学数值方法提供了合理的理论基础；从变分不等式的角度出发，阐述了对应于摩擦约束弹性、弹塑性问题的广义变分不等式理论，首次提出了在应力相容性条件下，它的有限元解具有存在唯一性，进而讨论了其有限元近似及离散解法；基于摩擦约束弹塑性广义变分不等式原理，首次提出了直接广义变分不等式方法，这一方法是直接变分法的合理推广和发展；利用直接广义变分不等式方法对金属压力加工中的平面变形问题、镦粗、挤压等塑性成形问题进行了分析计算，验证了该理论和数值算法的正确性、实用性、精确性和优越性。

OBAMA administration officials have been careful not to take sides in public statements on the hotly contested multi-candidate race, led by incumbent IRANIAN president MAHMOUD AHMADINEJAD and relatively-moderate former PRIME MINISTER Mir HOSSEIN MOUSAVI.

多人辩论赛正热火朝天地进行着，处于领先地全的是现任伊朗总统MAHMOUD AHMADINEJAD和相对温和的前总理Mir HOSSEIN MOUSAVI。奥巴马政府官员一直小心谨慎，在公开评论中不偏袒任何一方。

So, it is meaningful in practice and theory to probe into the application of Monte Carlo method in hydrodynamics.

本文首次较系统地讨论了蒙特卡罗方法在水动力学中的应用，积累了一些解决实际问题的成功经验，为以后进一步深入细致地研究打下了基础。

But the effect of her being on those around her was incalculably diffusive: for the growing good of the world is partly dependent on unhistoric acts; and that things are not so ill with you and me as they might have been, is half owing to the number who lived faithfully a hidden life, and rest in unvisited tombs.

但是，她的存在给周围人带来的影响曾经不可胜数地四处扩散：因为世上不断增长的善，部分地是由不具历史意义的行为决定着；而你我周围恶的事物之所以没有像它们本来会成为的那样坏，一半也要归功于那些忠实地过着隐秘的生活，如今安息在无人拜祭的坟茔中的人。

Similarly, the Digital Indicator in the loop in Figure 6.7 will update during each loop iteration.

同样地，在图6.7中循环中的Digital Indicator将在每次循环重复时刷新。

Furthermore,we find that the total time derivative of a function in Lagrangian has some relationship with phase factor of the wave function.

而且在具体计算过程中，我们发现在经典Lagrange量中的全微分项与波函数的相位有一定关联，但我们知道Lagrange量中的全微分项对其所对应的经典运动方程并没有影响，它可以在经典力学中被任意地舍去。

However, due to the large differences in economic development, social operation model, political system and cultural customs etc., there are many pecularities in China. We can see from the two following aspects: one is our the selection of pension institutions which possesses more character of "institutional dependency", and the determinative role of the evolvement of the pension structure on the choice of pension risk management mode can\'t directly be embodied, but the determinative role of the financial structure on overall the pension structure registers as the restriction of our financial system to the development of our private pension plans; the other one is that the magistral situation and product structure of traditional financial institutions, especially insurers, reflect our financial system is not quick to manage pension risk.

然而，由于我国在经济发展水平、社会运行模式、政治制度体制、社会文化习俗等方面与OECD国家存在较大的差异，我国养老金结构与金融结构的相关性也具有一定的特殊性，这种特殊性体现在两个方面：一是我国公共养老金计划主导的养老金制度选择更具有"制度依赖性"，并不能直接地、自然而然地体现出养老金结构演变对养老风险管理模式的决定作用，而金融结构对养老金整体结构的决定作用则更多地表现为金融系统对我国私营养老金计划发展的掣肘；二是我国传统金融机构特别是人寿保险公司在私营养老金计划中的主导地位和产品结构反映出我国金融体系管理养老风险的整体能力还不理想。

Let us therefore boldly face the life of strife , resolute to do our duty well and manfully

因此让我们勇敢地面对生活中的考验，坚定负责地做好该做的事

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
