Now, I wanted to see the pole it-self, and some eight hours after we met the submarine, we were crashing through that ice, surfacing, and then I was standing in an eerily beautiful snowcape, windswept and sparkling white, with the horizon defined by little hummocks, or "pressure ridges " of ice that are pushed up like tiny mountain ranges when separate sheets collide.

For feature extraction, this dissertation studies Barnard algorithm for Edge Point extraction and SUSAN algorithm for Corner extraction, Afterward, I put forward a method to extract inflexions, straight lines and curves based on Freeman Differential Code. Thus the use of Freeman Code can be extended and there will be more approaches to finish stereo correspondence.

在特征提取部分，本文对传统的Barnard边缘点提取、新近的SUSAN角点检测等技术做了详细的分析和研究，并在此基础上提出了基于Freeman差分码的多特征提取方法，包括拐点、直线及曲线，而且提取的直线利用多直线段分解法进行拟合，提取的曲线利用B样条技术进行拟合，最终形成有意义的轮廓。

Mouse fetal tissues could be cut into uniform small pieces by scissors cutting and needle grinding, which grew well in tissue culture and great amounts of cells grew from the attached small tissue clump to form primary mouse embryonic fibroblasts monolayer.

Like the central nave, the north was apparently decorated with one continuous panel. To the east, this gave way to a small design of crosses and squares. Enclosed in rectilinear edges, the panel showed a design of interlocked octagons, which, in turn. formed squares. hexagons and triangles. At some unknown date, this panel of white, black and red cubes was damaged by a crack which was repaired with white cubes.

像中殿一样，北边的长廊是由一个连续的窗格所装饰，直到东面才变为一个小的十字和方形的设计，并逐渐在边缘被密封，窗格由一连串的八角形设计，形成了方形、六角形和三角形，不知道在什麼时候，这些窗格的白色、黑色和红色的镶嵌块被损坏，这个裂缝被一个白色的镶块的修复。
