In the computation of aerodynamic forces, the present work is based on the work of Morino et al., but the following aspects are improved:(1) In computing the steady transonic aerodynamic load, the steady transonic nonlinear integral equation is solved by relaxation-iteration method in this thesis, instead of solving the time dependent transonic nonlinear integral equation, so that the computing time is saved greatly;(2) The influence coeifficients represented by volume integral are transformed to surface integral by using the Gaussian Theorem, so the analytical form of these coeifficients can be obtained and this leads to be more convenient to analyse and compile computer program;(3) The shock capturing method is used in every time step in present work, no shock moving term is added in the integral equation, so that it is more convenient and simpler to treat.

在气动力计算方面，本文基于Morino等人的工作，作了如下几方面的改进：（1）在计算定常跨音速流场（作为非定常绕流计算的初场）时，本文采用松驰迭代法直接求解跨音速定常非线性积分方程，而不是采用时间相关法求解非定常非线性积分方程，这样大大节省了计算机时；（2）将以体积分形式出现的影响系数化为面积分，并获得解析公式，这样便于分析和编写程序；（3）对运动的激波，本文通过在每一个时间步长上采用激波捕捉法而得到，而不是在积分方程中附加激波运动项，因而处理起来简单方便得多。

On the basis of an analysis of the present profile of automobile consumer credit in China,a discussion is done on the meaning of its development. This thesis introduces the development of the market of automobile consumer credit overseas, and finds out the reasons why overseas automobile consumer credit leads to the successful development of automobile industry. It also analyses the causes of the slump in the market of automobile consumer credit in the country in aspects of influential elements such as economy,policies,society,consumption norms and so on. It has a deep discussion on some obvious problems in this field. For example,the market of automobile consumer credit is of no scale; the prices of automobiles are high; taxes are heavy and expenses are too much; average residents still have low income and no definite balance between income and predicted expenses; there is no perfect social credit system and individual credit system; there is not enough awareness of credit among the public. Taking theories in the area of industrial economics into consideration,it proposes basic measures of promoting the development of consumer credit in China: building up a credited society,a perfect and sound personal credit system.With credit database as the platform,all parties will be able to share information,improve the credit database,relevant regulations and laws as well as a risk warning system,thus operation and management of the operating entities will be improved,the cost of the practice of consumer credit will be reduced; strengthen the innovation of present financial system,develop financial products corresponding to different groups of customers,improve services,perfect the mode of "bank+insurance+automobile agents",make full use of the interne,adopt the practice of turning credit into securities.

RESULTS: These familial keloids mainly occurred during adolescence, showing the equal chance of being affected between male and female subjects. The affected person could be heterozygous, and a child of an affected parent had a 50% chance of being affected. Thirteen subjects displayed familiar keloid, 1 suspected keloid, 2 did not present keloid as obligate carriers, and 1 did not present keloid as doubtful carrier. One pedigree displayed keloid in 3 generations, two displayed in 2 generations. The traits of familial keloids were transmitted interruptedly, revealing incomplete penetrance. The clinical phenotypes of familial keloids presented variable expression among the different affected.

In our thesis, contents are organized as following In Chapter 1 we present our topic's internal and overseas research situations, theoretical and practical significance, and introduce the research object and contents, and the main contributions of this dissertation. Chapter 2 reviews the development of the stability results for nonlinear systems and some relevant recent results, which include Lyapunov and LaSalle-Yoshizawa theorems for nonlinear systems, and stochastic edition for stochastic nonlinear systems. Sontag's formula for systems affine in control is presented in the frame of CLF. The concepts of disturbance attenuation and the inverse optimality are also explained in this Chapter. In chapter 3 we present the solvable theorem of inverse optimal gain assignment problem, design the inverse optimal controller and the inverse optimal tracking controller for strict-feedback nonlinear continuous systems with unknown time-varing bounded disturbances and constant unknown parameters using an adaptive backstepping algorithm, which are nonlinear, continuous and are easier to realize.

The model prediction is also compared with other theoretical models, for example, the Hashin-Shtrikman model for elastic constants and Kerner and Schapery models for thermal expansion coefficient. The model proposed in the present study shows similar precision on the properties of composites as the elastic modulus ratio is lower than 10. However, the elastic modulus ratio is higher than 20, the model proposed in the present study shows improved prediction on the properties of two-phase composites.
