Based on seismic, well logging, drilling and core data, five super sequence boundaries have been identified by using methods of sequence stratigrphy theory in deep formations of Shengping area, northern part of Songliao basion. They are the top boundaries of bed rock (SSB1), the bottom boundaries of Shahezi group (SSB2), the bottom boundaries of Yingcheng group (SSB3), the bottom boundaries of Denglouku group (SSB4) and the bottom boundaries of Quantou group (SSB5) respectively.

应用层序地层学基本理论，在综合分析工区地震、测井、岩心等资料的基础上，确立了超层序界面、准层序和准层序组识别标志，进而对松辽盆地北部升平地区深层进行超层序界面识别，共识别出五个超层序界面，分别为基岩顶面(SSB1)、沙河子组底面(SSB2)、营城组底面(SSB3)、登娄库组底面(SSB4)和泉头组底面(SSB5)。

An adaptive grid scheme controlling cell area is used to generated grids in the divergent section of symmetric annular nozzle, and the generated grids are used in the flowfield calculation through the uncoupled way. The elliptic equations are used to generate grids in three dimensional regions of FDN divergent section, the source terms used in the equations employ a mathematical form which is independent of the boundary shape and of the boundary grid point distribution, the free parameters contained in the source terms are determined by the two restraint conditions, the intersection angle of transverse grid lines with boundaries and the local curvature of the transverse grid lines at the boundaries, and the interior grid distribution controlled directly by the grid point distribution assigned on the boundaries is realized, it makes the grid more clustering near the nozzle wall. For the generated grids in the whole computational regions have a good smoothness and orthogonality, the accuracy of calculation in the flowfield is ensured.

对轴对称的环形喷管采用控制网格面积的自适应网格方法对扩散段部分进行了网格生成，并通过非耦合方式应用于喷管的流场计算中；对强制偏流喷管扩散段内的三维区域采用椭圆型方程进行网格生成，方程中的源项采用了与边界形状和边界网格点分布无关的数学形式，源项内的自由参数由横向网格线与边界的交角及横向网格线在边界处的局部曲率两个约束条件来确定，实现了由边界上的网格分布直接控制内部的网格点，使壁面附近具有较密集的网格，并且在整个计算区域内的网格都具有良好的光滑性和正交性，从而保证了流场计算的准确性。

First, we extract the boundaries between two different materials by weighting with gray-level gradient,and only voxels on these boundaries participate in the generation of each image, so it drastically reduces the rendering time. Second. We think the voxels on boundaries as the mixture of different materials,so in every voxel there is a surface. We use the oriented cube-interpolation technique to get the intersection point of viewing orientation and the surface in the voxel, then compute the surface normal of the intersection point. We use the normal to shade the voxel in order to improve the image quality.

首先，采用灰度梯度加权提取出三维数据场中不同物质间的边界，根据显示的需要只对这些边界上的体元赋予相应的阻光度并进行光亮度合成计算，因而可大大减少计算量，提高显示的速度；将边界上的体元作为不同物质的混合体，采用与方向有关的三线性插值来计算视线方向与体素内等值面的交点，根据交点的法向量进行光照效应计算以提高显示图像的质量；最后用投影成像法显示最终的图像。

Boundaries：界限

建议:助人者要学会设下界限(boundaries)尊重自己的时间与范围. 老年灵(Old Soul)一方面他们走退路,随意而懒散;而另一方面则加速心灵探讨的脚步. 不再汲汲追求成就,而一心准备迎接死亡,内心活动却极热络. 耽于官能享受、独立、往往相当孤僻.

Boundaries：边界曲面

个人因刚接触曲面时,对边界曲面(boundaries)命令比较偏好,所以向上题的方法靠拢,尽管让两端成为三边曲面(因为用boundaries)可我们先分析一下架构线,很显然两端比较难处理,怎样拆面会得到比较好的效果呢!
