These theories respectively are the governing theory, liability-control theory and trust-deputize theory. The reason why we choose these theory to analyses the problem of incorruptible style supervision system construction of China customs is that the China customs, in theory, ignored the governing of bureaucracy, incompatible the liability-control, and the problem of asymmetry information. Because of the problem of concerning above, in reality, China customs should be appear the problem like feebleness of power of uprightness lead, weakness of superior supervision, catabolizing of polity power, the emptiness of same grade supervision, and failure of incorruptible supervision.

本文认为从这些理论视角出发，我国海关在理论上正是由于不重视科层之间的治理，责任控制无法相互对应，和委托代理产生的信息不对称的问题，而在实践中必然出现现行廉政监督机制的制度缺陷：垂直领导体制下的集权弱化，上级监督&虚监&问题；监督组织政治权威的异化，同级监督&弱监&问题；基层单位高度集权体制下的监督虚化，内部监督&漏监&问题；惩罚失当使腐败收益上升成本降低，廉政监督&失灵&问题等四个方面的弊端。

The plastic deformation which is caused by the enrichment of edge dislocation with the same symbol, the incline crystal boundary which occurs when edge dislocation arranges vertically and the dissymmetry incline crystal boundary which is born of the distortion of crystal lattice are the three kinds of possible mechanism by which the graphite gets more crooked as nitrogen adds.

In the direct-location, with the precise model of satellite motion and its osculating parameters, a more accurate formula for the orbit calculation of satellite is obtained. Meanwhile, the determination of the position information of each pixel is more accurate with the precise model of earth shape.

二、直接定位中，通过建立精确的卫星运动轨道模型、卫星摄动模型，优选确定了卫星轨道计算公式，以提高卫星轨道计算精度；同时，采用对称椭球体的地球形态模型和融入卫星姿态的地面扫描点位置的计算方法，可使确定的地面扫描点的地理位置更精确。

Then applying Human Simulated Intelligent Control algorithm to the turntable control system has been designed to resolve the problems, which the load of the pitch channel is asymmetric and the rail's friction is uneven. The method has been verified in the real control system, and meets the requirements of the precision of turntable position. In finally, the algorithm has been simulated and tested correctly in matlab.
