查询词典 concaves

There are many heaves and concaves which can be observed on the surface of the layer, and so they make the surface of the layer rough. The surface of the layer is rich in Ti, but gradually the Ti decreases. It shows that The combine of the layer with the base is good, which result from the heat diffusing and chemical metallurgy reaction.

涂层表面由许多凸起和凹坑组成，表面稍粗糙，这是脉冲放电的工艺特点决定；涂层内部Ti元素由表层至与基体界面处呈梯度分布，并且Ti元素也渗入基体一定深度，说明结合良好，为冶金反应和热扩散的结果。

This paper analyzes the cause of small concaves around the welding seam in the long rail of Guangzhou Metro Line 2, and presents preventive measures, such as increasing the under layer of the rail, limiting the weld seam, lowering the welding temperature etc.

摘要结合广州地铁2号线接触焊焊接长钢轨的实践，分析了产生焊头表面小凹痕的原因，提出改变垫高钢轨的方式、缩小正火範围、降低正火温度、限制接头错牙量等预防措施。

During the prophase and anaphase of fruit growth, light,deep and very few V-type concaves generated in \'Kobayashi\' bag,\'Qianwei\' bag and unbagging fruit,respectively.

有袋栽培下可分离的主要放线菌是烬灰类群，另外还分离出白色类群、绿色类群和黄色类群等。2。

The traditional snake model only applies the features of the curve, which did not adequately apply the feature of the image. But in the algorithm, the corners of the detected object is detected based on the MIC operator; the initialized curve is set based on the corners; the object is fitted according on the snake model. The traditional snake model highly depended on the initialized position of the curve and can not get well fitted effort for the image which has the corners and concaves. The proposed algorithm preferably solve the drawbacks.

传统的snake算法只考虑曲线本身的特征，并没有充分的利用被拟合图像本身的特征，而此算法首先检测被拟和目标的角点，然后以这些角点为基准进行曲线初始化，最后根据snake算法进行目标拟和；较好地解决了传统snake模型对初始化位置敏感、对有角点和凹陷的图像收敛效果差的缺点。

Hexagonal flake-like Cd2 is the building-block to assemble doughnut-like microstructures. The block concaves from one side when PAM is present in the synthesis system.

这种结构是由单晶结构的六方片状Cd2按一定排列方式自组装而成。

Well-aligned nanoscrews are single crystals grown along the c-axis, with 18 sides on their heads but six concaves on their stems, while the whole is six-fold symmetry.

定向生长的纳米螺杆呈单晶态、c轴择优取向生长，且具有头部十八面体茎部六面体的结构。

A method and device for continuously supplying drops into female moldings which are rotatingly movable for manufacturing moldings, wherein synthetic resin in molten condition extruded from an extrusion opening is cut by a cutter attached to a holding mechanism to form the molten resin into drops in a determined quantity, the drops are held and conveyed by the holding mechanism, and the drops are forcibly inserted and supplied into the concaves of the female moldings.

是一种将用于对成形品进行成形的滴物向旋转可动的形成阴模连续供给的方法及装置，将从挤压开口部挤压出的熔融状态的合成树脂通过附设在保持机构上的切断工具切断、形成定量的滴物，利用保持机构将滴物保持输送，向成形阴模凹部强制插入、供给。

The GVF force does better than the other two forces in the segmentation of complex images with concaves. The gradient plus pressure force does better in preventing the model from crossing the slim images.［KEY WORDS］ image segmentation; active contour model; GVF; open contour model

对于简单的图像，梯度外力和梯度矢量流外力均能得到较好的分割结果；对于较复杂及边界凹陷的图像，梯度矢量流外力的分割效果明显好于其他外力；对于纤细图像应用梯度加压力的外力更容易控制模型越界的现象。

This kind of implant has the exact defect dimention, concaves andconcvexness, which apparently avoid in-operation shaping and tailoring, and make theoperative outcome more satisfactory.(4) A objective evaluation system can be established through the comparision of pre-op3-D imaging, in-op models, post-op 3D imaging. Also the feasibility of such kind of operationcan be appraised, if large sample is provieded.

4将患者手术前、手术模拟和手术后的三维数字模型应用逆向工程软件进行配准、分析，验证手术效果和手术设计方案的实现程度，(5)将患者手术后的颜面部数字化曲面模型和模拟的手术后曲面模型导入逆向工程软件，进行配准比较，验证手术设计方案的实现程度。

This devise is a pair of reformed chopsticks,which could economize efforts and adds more efficiency through the ribs shape of design at the botton to have more contact faces and points between chopsticks and foodstuffs. It is easy to clip tiny or slippery foodstuffs just like noodles, beans or eggs. On the other hand, this reformed chopsticks is more convenient than the traditional one which is in a pole shape or have concaves on it. The reformed one need not adjust the concave side to cilp foodstuffs.

本创作是一种更省力且使用更方便的改良快子，藉由筷子夹持端之肋条状设计，增加筷子与食物间之接触面积与接触点，对於夹取面条、豆类或卤蛋等外径、体积细小或表面圆滑之食物甚为方便有效，相较於传统圆杆状或表面设有内凹沟槽之筷子，本筷子不仅夹持力更佳，使用时更不需刻意调整设有内凹沟槽之部位来夹持食物，使用上更为方便省力。
