The method includes identifying (101) a surface in the image, and for each point in the image, calculating (102) a first curvature measure, forming (103) a set of rings of points about each point, each ring being of equal geodesic distance from a center point for the ring, calculating (104), for each ring, a standard deviation of the first curvature measure, and selecting (105) those rings with a minimum standard deviation for the first curvature measure.

该方法包括在所述图像中识别(101)表面；为该表面中的每个点计算(102)第一曲率量；为该表面中的每个点形成(103)围绕每个点的一组点环，每个环具有到该环的中心点的相等的测地距；为每个环计算(104)第一曲率量的标准偏差；以及选择(105)那些具有第一曲率量的最小标准偏差的环。

Beijing Institute of Cultural Relics and Archaeology,Beijing,China,100009Abstract The sedimentary characteristics and facies ofthe cultural layers in the late Paleolithic period of the late Late－Pleistocene in theWangfujing Oriental Plaza site were studied based on the comparison and analysis of thetypical sedimentation profile of the site and more than 150 stratigraphic data.The paleo－geomorphicsurfaces during the periods of 2.2×104a B.P.were rediscovered.The studysuggests that the ancients must have acted in the sandy islands of alluvial fans,whichwere evolved in relatively steady water flows during the interglacial stage with slightlywarming in the last glacial epoch.

沉积相与古地貌研究徐海鹏莫多闻岳升阳朱忠礼郁金城摘要：通过对遗址地层典型沉积剖面和遗址地区150余个地层资料的对比分析，揭示了北京王府井东方广场晚更新世晚期旧石器人类遗址地层的沉积特征与沉积相类型，从而恢复了距今2.2万年前人类在此生存活动的古地貌面。

The last glacial period, with two warming intervals, began at about 110 000 years.

末次冰期始于距今11万年，存在两个温暖期，冰盛期温度降低约9℃。

Full glacial conditions appear to have persisted in the region until about 15,000 years ago.

全冰川条件在这一地区似乎持续到距今大约15，000年前。

The current rate of increased carbon dioxide release into the atmosphere by humans may delay the onset of the next period of glaciation until at least 50,000–130,000 years from now.

由于人类向大气中排放二氧化碳的速度加快，下一个冰川时期的到来可能会有所延迟，至少在距今 5 万至 13 万年以后。

An Australian Antarctic Division glaciologist said the ice chunks, spottedby satellite photography, had passed the Auckland Islands and were heading towards the main South Island, about 450 kilometres (280 miles) northeast.

一名澳大利亚南极署的冰河专家说，卫星图像显示，这些冰块已经通过了奥克兰群岛，正向着距东北部450公里外的新西兰主要的南岛飘去。
