To calculate the aerodynamic forces on the vehicle and grid-fins, we use time-dependent method to solve the Navier-Stokes equation of ideal gas, and flux conservational multizones method to divide the complex vehicle and grid-fins into eight computational zones which are relatively independent, and correlative with each other at once with satisfactory results.

为了计算作用在飞行器和栅格翼上的气动力，采用时间相关法数值求解完全气体的三维Navier－Stokes方程，并运用通量守恒的分区计算方法，将复杂的飞行器和栅格翼系统分解成八个既相对独立，又相互关联的计算区域，得到了满意的结果。

The algorithm can be served as the inverse operation of raster to 2DRE quadtree, but it is not direct inversion, instead, it takes other simpler measur i.e. intersection of 2DRE quadtree and code transforming method in Raster to Quadtree conversion, to make the algorithm more effective. It can also avoid possible trouble of memory overflow caused by the operation on bigger images in smaller memory.

这一算法可看作栅格—2DRE四叉树变换算法的逆变换，但不是它的"反演"，而是采用了较为简洁的求交集运算以及栅格—2DRE四叉树变换算法中的编码转换方法，使得这一算法的实现更加有效，且避免了在图像较大而内存较小的情况下可能发生的"溢出"等矛盾。

From a uncertain point which located outside of the figure to draw radial, according to the junction of radial and polygon to judge the internal and outside relationship; Boundary algebra filling, a vector convert to raster arithmetic which based on integral thought, suit for polygon vector convert which

录拓扑关系的多边形矢量数据转换，方法是由多边形边界上某点开始，顺时针搜索边界线，上行时边界左侧具有相同行坐标的栅格减去某值，下行时边界左侧所有栅格点加上该值，边界搜索完毕之后即完成多边形的转换。关系，并表示成矢量格式边界线的过程。步骤包括：多边形边界提取，即使用高通滤波将栅格图像二值化；边界线追踪，即对每个弧段由一个节点向另一个节点搜索；拓扑关系生成和去处多余点及曲线圆滑。

Making use of this model I have a taste in Yan Shan Reservoir watershed in He Nan Province: I start on the information of the surface in this area, give every grid cell the proper parameters by distilling them from the map of how the people use soil and the map of soil type in this area; In order to get the topographical information, I add numerical value to a abundant of contour lines and points in topographical map, use the software Arc View of GIS to create Digital Elevation Models automatically, get every volume of the reservoir from the water level 99m to 117m. By using a special module of the software, I distill triumphantly the grid cells elevation value, slope value, flow direction, flow accumulation, watershed, stream network, isochrones and so on.
