查询词典 thinning

The trees may be cut as a part of a silvicultural thinning.

这些树木可以被砍掉作为造林疏伐的一部分。

For different silvicultural measures, the mechanical properties of Pinus sylvestris plantations were measured and analyzed. The results showed that the effect of silvicultural measures on many mechanical properties of Pinus sylvestris Plantations were not significant..In order to increase the mechanical properties of wood, growth-promoting and then get the better structure building lumber and glued lamination board, the stands on south slope or at the down of slope, and with density of 1.5m×1.0m, properly thinning could be selected. Results of this study can provide a theoretical base and good guidance for oriented breeding of Pinus sylvestris plantations.

摘 要：对不同培育措施的人工林樟子松木材力学指标进行测试和分析，结果表明：不同的培育措施（初植密度、间伐强度、坡向、坡位）对樟子松人工林木材的绝大多数力学强度指标有显著的影响，可选择阳坡、坡下、1.5m×1.0m、轻度间伐林分进行定向培育，来提高木材力学强度性能，从而加快林木生长，培育高产、优质的结构、建筑用材及胶合板材林。

Many skeletonization approaches have been proposed, try solving the defects that are intrinsic in traditional thinning algorithm, however, almost all approaches produce extra distortions; moreover, these approaches are usually applicable to some specific font only.

虽然许多的骨架化方法已被提出，试著克服传统细化的缺点，但这些方法几乎都会产生额外的失真，而且，这些方法通常只适用於某特定的字型。

The robustness is obtained thanks to the fact that some local mismatches in the approach are generally impossible to change the global correct matching trend The method can not only be used for sectional images matching in medical field as it did in the thesis, but can also be used in other fields, such as stereo vision [2] Distance transformation plays quite an important role in object thinning and skeletonization in image processing.

2〗距离变换是一种基本的图象处理工具，它在实现目标细化、骨架抽取等方面起到重要作用。作者提出了一种统一化的距离变换，它能够快速实现多种距离测度的距离变换。当进行欧氏距离变换时，其平均误差远远小于文献中现有的方法，并且出现误差的概率也大大地降低了。

Quantitative description and 3-D reconstruction of heart vessels are based on thinning vessels to skeletons with only one pixel width. But vessels extraction from angiogram decides the accuracy of vessels skeletonization.

利用心血管造影图像定量描述心血管病变和重建三维心血管，首要任务是将造影图像中的心血管表述成单个象素宽的心血管骨架，而心血管的提取又是心血管骨架提取和决定其提取准确性的关键。

The elderly man runs his bony fingers through his thinning hair and turns to the smirking student audience.

这位老师用他瘦峋的手指捋了下稀疏的头发，然后转向窃笑的学

Potential aderse effects of topical steroids include adrenal suppression, epidermal and dermal thinning, striae, and perioral dermatitis, she said.

她说到，局部类固醇治疗的潜在不良反应包括肾上腺抑制，表皮和真皮萎缩，皱折并可出现口周皮炎。

The mantle shear zone played an important role in continental blackup. Especially, the dissymmetry caused by simple shear deformation resulted in the different amount of extension in upcrust and subcrust, which in turn formed the detachment of the upper mantle from the crust, that is, the thinning positions of upper mantle and crust were different.

地幔剪切带在大陆裂解过程中起关键性作用，特别是简单剪切变形所产生的强烈不对称构造，以至壳上伸展量明显不同于壳下伸展量，壳幔明显折离，使得壳幔变薄区的位置明显分离，这将能很好地解释华北地台东部岩石圈地幔演化及其浅部盆地形成等的响应。

Firstly, the pretreatment of character to be recognized is researched, stressed discussing the subdivisional process of character, and a kind of fast shape preserving morphological thinning algorithm is used. In the following, how to construct the structure model on the basis of characteristic point sub-stroke and their interrelation is discussed, and a kind of method that describe sub-stroke through the feature of the sequence of curvature is brought forward. Finally, the paper adopts the recognising model of printing number that base on repository, and describes the constructing method of repository.

文中首先对待识别字符的预处理进行了研究，着重探讨了字符的细化过程，采用了一种基于数学形态学的保形的快速细化算法；接着探讨了如何以特征点和子笔段及其相互关系为基础构造结构模型，提出了一种以曲率序列性质描述子笔段的方法：最后采用了以知识库为基础的印刷体数字识别模型，并详细地描述了知识库的构造方法。

Obliterationof the fat planes around the ligament, extravasation of jointfluid into the adjacent soft tissues, and talar contusions mayalso be seen. Chronic tear often manifests as thickening, thinning,elongation, and wavy or irregular contour of the ligament.

韧带周围脂肪层的消失，关节液外渗出到周围软组织消失，及可见距骨挫损，慢性损伤常出现增厚，变薄，延长，及韧带轮廓呈波浪状或不规则状。
