The system state transition matrix is deduced, so the zero effort miss of the interceptor can he solved with numerical method under considering the earth's oblateness effect of J2. In order to make the thrust direction change smoothly and make the zero effort miss decrease quickly, the engine thrust is decomposed along the line of sight direction and perpendicular to the line of sight direction, and the distribution proportion coefficient is designed based on the required velocity gain normal to the line of the sight.

推导了系统状态转移矩阵，通过数值方法求解得到考虑地球扁率J2摄动项的拦截器零控脱靶状态，在此基础上将推力分解到视线方向和垂直视线方向，并根据垂直视线方向需要速度增量大小设计了推力分配比例系数，使得推力方向平稳变化且能快速减小系统的零控脱靶量。

This project have done an in-depth data mining to the data of circuit breaker on-line working conditon monitoring system, and implement some effective circuit breaker on-line working conditon monitoring data analysis diagnose methods, promote the development of the analysis and research of other devicess on-line working conditon monitoring in the substation too.

A contour tree has found many important applications in map generalization,terrain analysis,etc.with respect to generating contour tree,this paper has proposed a scan-line based method,this method translates intersection point pair of scan-line and contour line as range,explains containment relation between range as containment relation between contour lines,determines "one-many" direct containment relations between parent contour and child contour by this method.

中国科学院计算所，北京 100080摘要等高线树在地图的产生、地形分析等应用中具有较重要的应用。对于产生等高线树，提出了一种基于扫描线的方法，该方法把扫描线和等高线之间的交点对解释为区域，利用区域之间的包含关系对应等高线之间的包含关系，以这种方式来确定父等高线与子等高线之间的"一对多"直接包含关系。

In addition, the magnetic noose tool was used to outline the contour line of inside and outside boundary, and obtain the inside and outside contour line of every layer of the femur. The rabbit femur was scanned by industry CT starting from the upper extreme of the femur, vertical to femoral ordinate axis line (slice space=1 mm).

再用磁性套索工具勾勒各层图像的内、外边界线，得到各层面股骨内、外轮廓曲线，采用CT 扫描机对兔股骨进行扫描，自股骨头上端起，由近端向远端垂直于股骨纵轴行CT 扫描，层间距为1 mm。

An analytic solution of kinematic model was obtained via Lie transformation group. It shows that the velocity of particles flow is maximum when x=0. Through locating the maximum particles velocity distributing line and taking the line as the origin line of x coordinates, the modified kinematic model could simulate the eccentric discharging well.

通过Lie变换群得到"运动模型"的解析解，发现x=0时颗粒的垂直速度达到最大值，由此在确定颗粒最大速度分布线的基础上移动坐标使该线上x值均为0，对"运动模型"进行了修正，可以反映壁面对颗粒运动的影响，所得计算结果与实验测定吻合得很好。
