From the point of practice and dvelopment, how to impove the ability of credit risk management for Yinchuan city commercial bank is discussed surrounding the client raiting and credit extention, measures of credit risk, management strategies of credit risk, conclusions of the paper are listed as the following:Through positive analysis, the current methods of client rating and credit extension is simple and convenient for application, there are four disadvantages in index system of it: non-customer subdivision, non-consideration factors on industrial risks, larger quantitative indicators ratio, non-consideration factors on affiliated enterprise risk, and some corrective measures are put forward to solve it, customer subdivision, factors-added on industrial risks, set stationarity indices ratio in reason, factors-added on affiliated enterprise risk; From the point of development, Based on the technology of Value-at-Risk and CreditMetrics model we discussed the methods of credit risk analysis and measurement and gave the example of how to calculate the VaR value of individual loan and combined loan; This paper probes into the strategies which raise the ability of credit risk management for Yinchuan city commercial bank from five aspects, including strengthen the inner control, improve the technique level of risk management through information technique, solve the problem of non-performing loan, adjust the credit orientation and structure, foster credit culture with its core based on risk control.

从实践和发展的角度出发，围绕客户评级授信、信贷风险测量、信贷风险管理策略三个方面，就如何提高银川市商业银行信贷风险管理水平展开研究，得出以下结论：通过实证分析，银川市商业银行现有的客户评级授信方法具有方法简单、易于推广的优点，但客户评级授信指标体系具有客户分组不细、未考虑行业风险因素、定量指标占比过大、未考虑关联企业风险因素的缺点，应通过细化客户分组，增加行业风险因素指标、合理设定定性指标比重、增加关联企业风险评价指标等措施进行改进；从发展的角度出发，在基于VaR框架和CreditMetrics模型技术的基础上，探讨了银川市商业银行信贷风险分析和度量的方法，给出了采用CreditMetrics模型技术计算单笔贷款、组合贷款VAR值的例子；从五个角度探讨了提高银川市商业银行信贷风险管理能力的策略和手段，包括强化信贷风险内控管理机制、利用信息技术提高信贷风险管理技术水平、综合治理化解不良资产、调整信贷结构、建立以风险控制为核心的信贷文化等对策。

In studies of interaction among pile, platform that above it and surrounding soil, this paper employ the concept of plate element to simulate the loading character of platform, and employ the concept of solid element to simulate the character of pile and soil, using the finite element method after understanding the geometry properties of pile, soil and the platform. Analyzing the loading properties of the three entities above and their deformation, this paper also employ a special element, Penalty Element. The introduction of penalty element of this kind has served to guarantee the join harmony of displacement between solid element and plate element, thereby effectively resolving the join problem between platforms, pile that support it and surrounding soil.Considering significant property difference between pile material and its surrounding soil, there may be much shear stress on their contact interface produced under vertical load, thus causing displacement or fission. Therefore it is necessary to adopt one special constitutive law of this kind of contact interface, which can reflect its feature of loading and deformation thoroughly. On the basis of the deformation feature and constitutive laws of some contact interface obtained by Zhang Dongji and people concerned through some single-shear experiments on contact interface between structure and soil, this paper employ one pile-soil three-dimensional constant thickness contact interface model to simulate the " slide" taken place on the interface between pile and its surrounding soil. With this kind model, this paper has also created one finite element model, which can be applied to perform finite element calculation and analyze the pile-loading feature, and deduced its element stiffness matrix.

在承台-桩-土共同作用中，考虑桩与承台的几何特性，采用有限元方法，用实体单元模拟桩土，用板单元模拟承台，更具体地分析桩和承台的受力特性和变形，而且还采用罚单元—既实体单元与板单元之间连接必须满足变形协调条件，来有效地解决了承台与桩土的连接问题，且在桩土共同作用中，由于桩体结构的材料性能与周围土层性质相差较大，在竖向荷载下有可能在其接触面上产生较大的剪应力从而导致错动或开裂，因此，为了充分反映桩土接触面上的受力及变形特征，应采用一种桩土接触面特有的本构关系，即利用张冬霁等人关于结构与土体接触面单剪试验所得到的接触面变形特征及其本构关系，引入桩-土三维等厚度接触单元来模拟桩与桩侧土之间的&滑移&，在此基础上建立可用于桩基承载性状分析的有限元计算单元模型，并推导出了各单元的刚度矩阵。

For non-diagonal processes there is "Coherent enhancement" therefore the one-phonon processes are more important than the two-phonon processes; At the same time, we presented a new theoretical framework of phonon-assisted energy transfer, in which the running lattice wave theory is introduced instead of the Debye theory for phonons,therefore emphasizes the important effects of optical phonons and coherence effects of anisotropic lattice waves etc.
