This paper quantitates financial risk by constituting the model of measurement financial risk. And the samples are from the public companies'merger and acquisition from 2002 to 2005, this paper demonstrates perfectly the influence of financial risk of acquisition companies from different payment methods. The result of test analysis shows: in one side, the theory of risk-return is unfit in China (by being educed conclusions by other students: different payment methods bring different return, then the author detrusions different payment methods bringing different financial risk, and being tested direct proportion each other); in the other side, this paper answers different payment methods bringing different degree financial risk of acquisition companies: the smallest financial risk from cash payment method, the mean from commingle payment method, the biggest from stock payment method, which can supply reference in the choice of rational companies between payment methods and financial risk .

通过建立企业财务风险度量模型，将企业财务风险量化，并以中国上市公司2002年—2005年间的并购案中所采用的支付方式为样本，对我国上市公司并购中不同支付方式对并购方财务风险的影响做一个较系统、完善的实证检验，一方面从理论上验证了风险-收益理论的在我国的不具有适用性（通过对前人研究结论：不同支付方式带来不同收益，进而反推不同支付方式带来不同的财务风险，验证得出二者成正比关系）；另一方面回答在我国目前市场条件下并购中的不同支付方式引起收购公司不同程度的财务风险，其中现金支付方式下给收购公司带来的财务风险最小；混合支付次之，股票支付方式下财务风险最大，能给企业在并购时选择支付方式与财务风险的最佳组合提供参考。

By using generalized-weak commutativity mapping, the existence of common fixed point for this class of contractive type mappings is studied in complete metric space, a common fixed point theorem for contractive type mappings is obtained, which largely improve and extend the corresponding results in some references.

通过使用映象的广义弱交换条件，在完备度量空间中研究了更为广泛的一类压缩型映象的公共不动点的存在性，给出了一个新的公共不动点定理，从而在很大程度上改进和推广了现有文献中的一些结果。

That not only could be extended to the continuous random varia- ble,but also the theorem of maximum information measure could be extended to the continuous random variable, which unified the measurement arithmetic of information between distributed random variable and continuous ran- dom variable,and gave two validating models to the information entropy of the continuous random variable in the last.

用公理化的方法，推导出了有限分布列的离散型随机变量的信息量系，不仅将它推广到连续型随机变量，而且将信息量系的最大信息量定理推广到连续型随机变量，统一了离散型和连续型随机变量的信息度量算法。最后利用得出的结论对连续型随机变量信息熵给出两个验证性算例。

In an experiment of constructing a phylogeny of the Eutherian orders, its results not only support the Rodents,(Ferungulates, Primates grouping, but also give an evolutionary tree that is identical to the one constructed by the maximum likelihood method, which indicates that sequence distance defined is very effective to measure the relatedness between sequences.

在研究基于基因组序列的进化关系的实验中，不仅支持了哺乳类动物中（啮齿动物，（灵长类动物，Ferungulates））进化关系分类的结论，而且构造的进化树也与由最大似然方法构造的进化树完全一致。这充分说明了我们给出的序列距离对度量序列相似性是非常有效的。

I present cluster schema for combinatorial problem with clustering, design a new crossover operator cluster crossover, study the survival probability of c-schema under c-crossover, apply it successfully to graph coloring, load balancing and maximum spanning tree problems: give measurements of diversity in GA, set up varying crossover probability algorithms to maintain diversity, obtain good results when apply it in avoiding premature convergence and multi-modal functions optimization; establish GAC to be suitable for non stationary function, it can explore the change of environment and find the best solution even for some"anomalous"function.

针对聚类组合优化问题提出了聚类模式，设计了一种新的交换操作：聚类交换并研究了聚类模式在聚类交换操作下的生存可能性，成功的将聚类交换思想和算子应用于图着色、负载平衡和最大生成树问题，佐证了类理论，表明类理论可以指导新的应用算法设计；给出了GA中多样性的度量标准和维护多样性的动态交换概率算法，用于避免过早收敛和多峰函数优化，取得了较好的结果；构造了维持种群多样性以适应动态环境的方法GAC，在某些现有方法无能为力的问题上，GAC能够探测到环境变化，找到当前最优解。

To study local influence of the data cases on the Score statistic for the test of varying dispersion in the nonlinear model of simplex distribution, this paper develops the local influence on the score test statistic under perturbation in the response variable and explanatory variables based on gradient method.

为了研究数据对于单形分布非线性模型变离差检验的Score统计量的局部影响，该文利用梯度方法分别研究了因变量及自变量的微小扰动对于该模型的Score检验统计量的局部影响，相应得到了度量最大局部影响的诊断统计量。

Three theories dominate:(1) it is being dissolved in the ocean, and then it precipitates to the sea bottom as carbon rain; or (2) it is being deposited in soils by microbes; or (3), most controversial, the lost carbon is fueling growth of the world's savanna grass, or being turned into tree wood, on an imperceptible but massive scale that we haven't yet been able to measure.

其中有三个理论作为主导：(1)溶入了海洋，最终作为碳雨沉到洋底；(2)被微生物储存到泥土中；(3)最具争议的，消失的碳促长了全世界的大草原，或者变身为树木，形成一种我们未曾察觉、不能度量的大循环。

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。
