袁科长说，高铁建成以后，可以带动德诚区的发展，德诚区在我们城市西北方面，呈扇形，只有50多万人口，整个德州市有500多万人口，有小磨拉大车的现象，所以德州市政府有意征地扩大城区，在征地过程中，高铁项目进驻德州市，站址规划在开发区，位于德诚区的东侧，高铁项目建成以后，以德州高铁站为中心可以把人流、物流等吸引过去，可以辐射开来，达到扩大城区的目的。

Analysis result shows that the dynamic interaction between wheel and rail and the rail-pad force of the strengthened track are little bigger than those of the unstrengthened track,the safety grades of the tracks are same,the strengthened track can benefit to decrease the displacements of all components of track structure obviously,to restrain the deformation of track effectively,and to reinforce the stability of railway,especially the lateral displacement and the gauge enlargement of the strengthened rail are about 33% of original rail.

分析结果表明：强化后轨道结构的轮轨动态相互作用力及轨枕支点压力均较强化前的相应值略大，但皆属相同安全合格等级；强化轨道结构位移大幅度降低，有效抑制轨道结构变形，增强线路稳定性，尤其是钢轨横向位移和轨距动态扩大量较强化前下降十分显著，前者仅约为后者的1/3左右；强化轨道也有利于降低轨下结构振动和减轻列车提速后对轨下基础的破坏。

The computation model of two-point contact (for cone-tread) and conformal contact (for worn-tread) resulting from wheel flange close to rail is firstly established in this paper. A detailed analysis is made of the wheel/rail contact force, contact status and wheel/rail stress distribution on the different action of tractive forces and transverse forces. We draw some important conclusions, one of which is that the locomotive adhesion performance will decrease with the increase of transverse forces between wheel and rail.

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.
