通过对下扬子区中、新生代非对称性沉积盆地的几何学特征分析，认为这种非对称性构造沉降盆地在剖面上表现为由一组主边界断层和一组天折的共轭断层所围限，而且在走向上具有分段特征。

The causes of shield tunnel defections could be divided into six branches: the segment dislocations, lining material deterioration and seepage. etc. Fault trees are also founded to illustrate each branch. 23 quantitative elements from the fault trees are selected to serve as the diagnosis indexes, all of which could be applied in engineering practice. By using the AHP method, a 3-level diagnosis index system is established. Afterwards, the procedure of setting up the quantitative judging criteria is given, as well as the relative index weight of index layer, by using the improved Analytic Hierarchy Process-multiplication scale method. At last, the values of corresponding parameters of membership functions are set, with the Cauchy distribution model.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
