On the basic assumption of Corporate Heterogeneousness Nature, integrating marketing, finance, economics and other related subjects, the thesis carrys out overall SWOT analysis of our country's banking industry and exactly describes our country's banking ecological overview; the thesis explores the sources and formulating mechanism of marketing competenece of our country's banking industry enterprises; integrating the specificities of bank marketing, especially the banking product's four essential attributes: intangibility, inseparability, inconsistency and inventory, the thesis formulates a bank marketing competence evaluating indicators system that is compatible with the

本文在综合营销学、金融学、经济学和其他相关学科的基础上，以"企业异质性"为基本理论假设，为我国银行业进行了全面的SWOT分析，准确地描绘了我国的银行生态图景；探讨了我国银行业企业营销竞争力的基本来源和形成机理；结合银行营销自身的特殊性，尤其是银行产品的四个本质属性：无形性、不可分割性、非标准性和非存储性，构建了切合我国银行业实际的银行营销竞争力评价体系。

The first chapter presents a comprehensive study of nonholonomic dynamics. They are studied that the nonlinear problem and un-determinate problem of virtual displacement in nonholonomic system in the second chapter. In chapter 3, they are studied that Chetaev model and Vacco model in nonholonomic system.

As one of the leading branches of the modern statistics, the riouparametric regression analysis is widely applied to explore the relationship between the the response variable y and the covariable A'.

对于非参数回归人们提出了许多估计方法，如核估计，局部多项式估计，光滑样条估计，级数估计(傅里叶级数估计，小波级数估计)等。这些方法本质上讲都是局部估计或局部光滑，当回归变量X为一维变量时，非参数回归函数用这些方法一般都能得到很好的估计。
