Suggested by the deformation and shift data of Xigeda Group, Middle Pleistocene, an obvious zoning in stress pattern is appeared in Xichang area, Sichuan Province. That is to say, demarcating approximately at Lizhou, the northern part (around Lugu-Mianning) is mainly of intense folding deformation, with a probable principal compression stress of WNW direction; but in an area south of Lizhou (near Xichang and Qionghai) tensile normal faults are vastly developed, featuring an extension area. This paper aims at...

Suggested by the deformation and shift data of Xigeda Group, Middle Pleistocene, an obvious zoning in stress pattern is appeared in Xichang area, Sichuan Province. That is to say, demarcating approximately at Lizhou, the northern part (around Lugu-Mianning) is mainly of intense folding deformation, with a probable principal compression stress of WNW direction; but in an area south of Lizhou (near Xichang and Qionghai) tensile normal faults are vastly developed, featuring an extension area. This paper aims at how to deduce regional stress field from those locally tectonic deformation relics, and how to better explain such a peculiar phenomenon of both compression and extention existing in a small area.In this paper, from a viewpoint that the dynamic property difference in geologic medium is the main factor effecting local stress status, an evolution model of "edge to edge-vertex to edge" contact relation between rigid blocks has been presented, which can be used to better explain the above phenomenon. Finally, using plane finite element method the stress field in Xichang area has been simulated, obtaining calculated results coincident with the available data.The evolution model of "edge to edge-vertex to edge" contact relation between rigid blocks has certain enlightenment significance in origin explanation of a series paternoster narrow basins and depressive valleys in Southwest China.

四川省西昌地区中更新统昔格达组地层的变形变位等资料表明,该区的应力图象具有明显的分区性。即大致以礼州为分界,北部泸沽、冕宁一带以强烈的褶皱变形为主,推测其主压应力方向为北西西;而礼州以南的西昌、邛海附近则广泛发育张性正断层,表明是一引张区。如何从这些局部的构造变形遗迹反演区域应力场,并较好地解释在一小范围内挤压和引张共存的特殊现象,是我们的目的。本文从地质体介质力学性质差异是影响局部应力状态的主要因素这一思想出发,提出了刚性块体接触关系的“边边—点边”演化模式,能较好地解释上述现象。最后,用平面有限元方法模拟了西昌地区的应力场,计算结果与实际资料吻合。“边边——点边”块体接触关系的演化模式,对于解释西南地区一系列串珠状窄长盆地和断陷谷的成因具有一定的启发性意义。

In digital image mosaicking, search of seam points is the key procedure. It is usually to be done based on certain criteria to select the seam points row by row. In one-dimensional seam point search algorithm, the horizontal artificial edges are more significant than the vertical. In this article, a two-dimensional seam point searching algorithm is suggested where the grey level differences in the vertical direction are concerned as well as in the horizontal direction. Algorithm for mosaics of multispectral images is also introduced. Experiments show that with the method proposed, the artificial edges in the mosaics can be smoothed effectively.

在计算机图像镶嵌中,两相邻图像间接缝的选择是个关键性步骤。常用的方法是根据某种误差准则来逐行(列)选择接边点。现有的误差准则中存在的问题是水平接边质量比垂直接边的质量差。本文提出用两维接边准则代替原有一维准则,使水平接边与垂直接边质量相当。对多波段彩色合成图像数字镶嵌,提出了在三组图像重叠区加权绝对灰差和图像上用两维准则选择寻找接边点的方法。取得了较好的结果。

In the traditional divide algorithm for intersection of two parameter surfaces, it is impossible to simply calculate the intersection of polygons approxi mated from divided surfaces because of the, thickness of the polygons. An improving algorithm is presented which has eliminated some unreasonable phenomena, such as intersection segments lost, by considering the relationship among faces, edges and vertices of polygons in global view, and by computing the intersection of any two polygons under environment of...

In the traditional divide algorithm for intersection of two parameter surfaces, it is impossible to simply calculate the intersection of polygons approxi mated from divided surfaces because of the, thickness of the polygons. An improving algorithm is presented which has eliminated some unreasonable phenomena, such as intersection segments lost, by considering the relationship among faces, edges and vertices of polygons in global view, and by computing the intersection of any two polygons under environment of all polygons. It has been proved by experiments that the algorithm is robust.

本文认为,在传统的参数曲面分割求交算法中,由于近似多边形存在厚度,因此不能用简单的方法计算近似多边形的交线。文章提出了一种改进的算法,该算法以整体的观点考察多边形的面、边、点之间的关系,把两多边形之间的求交放到全体多边形中去考虑,从而避免了两参数曲面的交线出现裂缝、丢失或增多的现象。实践证明,这种改进算法是可靠的。
