边缘的

A variational formulation level set model based on the image global information is obtained, which can detect contours both with and without gradient based on global information and eliminate the re-initialization procedure. The stopping term does not depend on the boundary gradient of the image, which overcomes greatly the "over segmentation".

针对这种情况，该文提出了一种基于图像全局信息并且不需要重新初始化的变分水平集红外图像分割方法，不考虑图像边缘梯度的影响，将图像全局信息作为外部能量项，在很大程度上克服了边缘模糊时过分割的情况。

The contents of volcanic grains increase upwards in the stratigraphic section, and become dominant during the Early Albian.

侏罗纪晚期，砂岩物源来自于稳定的被动大陆边缘，早白垩世Barremian期砂岩物源来自于被动大陆边缘和火山弧的双重供应，随地层变新火山物质的输入逐渐增加，至Albian早期达到顶峰。

And according to the directions, the Bandelet blocks were classified into two sorts: the Bandelet blocks with geometrical directions and the Bandelet blocks without geometrical directions, and the different characteristics of the two sorts of Bandelet blocks were analyzed in order to distinguish the noise and signal, and the weak contrast features and the strong contrast features.

根据图像增强方向将Bandelet块分为两类：有几何方向的Bandelet块和无几何方向的Bandelet块，并分析了这两类Bandelet块系数的不同特征，从而区分出噪声和信号、清晰边缘和脆弱边缘。

分水岭算法具有很强的边缘检测能力，对微弱的边缘也有较好的效果。

In contrast, P. obliquum has lamina with basal pinnae contracted, scales of petiole brown adaxially, scales of rachis up to 2.3×0.5 mm, pinnae green, chartaceous, matt adaxially, and serrulate on margin, and microscales 0.2-0.5×0.1-0.2 mm.

Culm sheaths green, densely glaucous, abaxially glabrous or hairy, densely so at base, margins ciliate and apically orange or withered; auricles obscure; ligule truncate, 1–2 mm, densely glaucous, ciliolate; blade narrowly lanceolate, margins serrulate.

绿色的竿箨，密被白霜，或者有毛的背面无毛，浓密因此在基部，边缘具缘毛和顶部橙或者枯萎；叶耳不明显；叶舌削去，1-2毫米，密被白霜，具短缘毛；狭披针形的叶片，边缘有细锯齿。

The Caledonian granitoids,majorly distributed in the northern Qimatage mountain,showing geochemical characteristics of Cordilleran I-type grantiods,low-K high-Ca amphibole-bearing calc-alkaline granitoids or peralkaline and alkaline granitoids,and associated with an active continental margin or back-arc basin,indicated the existence of the Qimatage ocean-related limited subdu...

研究表明加里东晚期（430 ～370 Ma）花岗岩主要分布于祁漫塔格山北坡，具科迪勒拉I 型花岗岩或ACG、PAG 特征，代表活动大陆边缘或弧后盆地构造属性，加里东晚期祁漫塔格北坡至少存在洋壳的有限俯冲；华力西中期（320 Ma ±）发育伸展型富钾低铝钙碱性花岗岩，类似加里东I 型、CPG、KCG 花岗岩特征，广布于祁漫塔格山和求勉雷克山区，形成于碰撞后构造环境；华力西晚期（270 ～250 Ma）具科迪勒拉I型或ACG 特征，属活动大陆边缘构造环境，其形成与早二叠世特提斯洋的向北俯冲作用有关；印支—燕山期（220 ～160 Ma）具A2 型或富钾低钙钙碱性花岗岩，形成于碰撞后挤压向拉张转折过渡的构造环境。

WOX3 specifies the cell fate at the margins of cotyledonary primordia and regulates the rate of cell division in the margins of meristem in Arabidopsis.

阿拉伯芥的PRS/WOX3基因参与子叶原基边缘细胞专一性的决定，及调控分生组织边缘细胞分裂的速度。

In the most caudal extent of the striatum, there was also a dense band of CGRP-positive fibers in the lateral border of the caudate putamen and the direction of the fibers was also dorsoventral. There are some transverse CGRP-positive fibers connecting the MrD and Cpu.

CGRP免疫阳性纤维分布越靠纹状体尾，则纤维越密集，且阳性带越宽；（2）在纹状体的最尾侧，除边缘区外，尾壳核的外侧缘也出现一条致密的阳性纤维带，与边缘区走向一致。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
