Chapter Three expounds the contents of the main risks confronted our state-owned commercial banks in current situation and then analyzed the cause of formation of the main risks. I hold the opinion that the key factors that curb the improvement of risk management in our state-owned banks are as follows: the limitation of the property right system, the imperfectness of the credit legal system and the backwardness of the technological means in risk management.

The press spokesman's system, which arose in the west, was introduced into China in 1983. It catered for China's diplomatism and external propagandizing. The press spokesman system was established broadly in the State Department, all the State Department's branches and local governments in 2003, which was accompanied by the comprehensive implementation of the new generation of central leaders' ideology of "governance for the people", the thorough revolution from "all-mighty government" to "serving government" and the lessons of the affair of SARS.

发轫于西方的新闻发言人制度，在我国肇兴于1983年，当时主要是出于外交的考虑和对外宣传的需要。2003年，随着新的中央领导集体"执政为民"思想的全面铺开，随着"全能型政府"向"服务型政府"的全面转型，也鉴于非典事件的教训，新闻发言人制度以国务院、国务院各部委和地方政府三个层次在国内广泛确立。

The system parameters are determined by optimizing an output-error cost function. To deal with the non-uniqueness of the fully parameterized state-space system, a projected gradient search algorithm is presented by restricting the update of the parameters to the tangent space to the manifold of observationally equivalent state-space systems. The sufficient condition to employ L-M algorithm for optimizing parameters is also introduced. The proposed hierarchical optimization identificationmethod includes two steps: First, the parameter search direction is determined by the proposed adaptive L-M projected gradient approach; Second, the optimum step size is computed according to a line search method.

The first one is an algorithm with terminal sliding mode equality constraint. The second is a dual-mode control scheme, which enlarge the terminal region. The sliding mode based MPC is implemented while system state is outside of terminal region, and sliding mode variable structure control designed off-line is used once system state arrives in the terminal region.

第一种方法为终端滑模等式约束非线性模型预测控制方法，首先离线设计切换函数使得滑动模态渐近稳定，然后在有限预测时域的基础上对切换函数附加一个终端等式约束；第二种方法为双模控制方案，在终端区外采用模型预测控制，使得系统状态在有限时域内到达终端区内；在终端区内部采用离线设计的滑模变结构控制，使得系统渐近稳定。

On one hand, every organ, tissue and even cell of the body participates in and affects the state of serum lipoprotein dynamic balance in different degrees. On the other hand, SLDB is a direct factor for maintaining the normality of whole vascular system, especially the vascular endothelium system. The serum lipoprotein dynamic imbalance, as an inducement or even etiological factor, can bring about various clinical diseases. Therefore, integrated analysis is needed to appropriately assess the state of SLDB.
