查询词典 veins

In addition, the edges, veins, skeleton and fissility of plant leaf are also primary features for plant morphology. So we also studied the method of the automatic extraction of these structural features from leaf images, which is a necessary step to design an automatic plant species system.

另外，叶片的叶缘、叶脉、骨架、裂深等叶片结构特征是植物数值分类学的主要分类性状，也是植物形态学分类的依据，通过数字图像处理技术实现这些性状的自动提取，是计算机辅助植物物种识别的重要内容和必然环节，所以对这些叶片结构特征的自动提取方法也进行了研究。

Many Kinds of syn-sedimentary deformation structures have been found in seismite, including stepmicro-faults, micro-corrugated laminations, vibrational liquefaction sandstone and clay veins,loadingstructure, flamboyancy structure and so on. By the analysis of seismite of single well,seismite sequence have been put forward.

通过岩心观察和描述，在黄骅坳陷古近系中识别出震积岩，主要标志为同沉积变形构造，包括小规模阶梯状正断层、微褶皱纹理、振动液化砂泥岩脉、负荷构造、火焰构造等，通过单井岩心分析，建立了震积垂向序列。

Many experiments indicate that flocculus steel balls possessing reticulate veins surface tend to elastic fluid kinetic lubricating layer and improves of the lubricating conditions of bearings.

而且许多实验表明：表面呈现网状纹理形貌的"绒面"钢球，有利于钢球和套圈之间的点接触区域形成全膜弹流润滑层，使得轴承的润滑状态得到改善，从而实现轴承减振降噪和提高寿命的目的。

Finally steel balls millstone covering with Ni-Fe-diamond composite electro-brush plating film is produced successfully.Secondly, the steel balls millstone is used to grind steel ball in ones steel ball factory, and process flocculus the steel balls that possess reticulate veins surface.

然后利用制成的钢球研磨板对钢球进行超精磨削加工，加工出了表面具有网状纹理形貌的"绒面"钢球，利用仪器测量钢球表面的粗糙度值达到了0.015μm，表面波纹度值达到了0.006μm，圆度达到了0.010μm，球批直径变动量小于0.015μm。

It is shown that the distribution of their veins were similar; and both wings tend to be much stiffer under upward loading than under downward loading; the area of a forewing is smaller than that of a hind wing from the same dragonfly; and the structural performance of the forewing is superior to that of the hind wing.

对具有不同起拱、起皱高度的计算模型进行静力分析，发现起拱和起皱的幅度越大，结构的刚度也越大，但单位面积上所用的材料则呈非线性增加，相应地增加了结构自重。

For comparison reason, the planar and spatial models based on a forewing structure were analysed, it is shown that the cambered corrugation in the wings can improve the flexural stiffness of dragonfly wings effectively; the veins distribution and their size variation in different zones are quite reasonable.

对前翅平面模型和立体模型的静力性能进行了对比分析，发现翅膀中的起拱、起皱结构可显著提高蜻蜒翅膀的弯曲刚度；分布在翅膀不同区域的翅脉横截面尺寸与其受力大小是完全相适应的。对翅膀模型分有膜、无膜两种情况进行对比分析，得出翅膜中产生的膜应力刚化效应可有效改善翅膀结构的刚度。

Methods To improve the technique on the base of traditional way,52 patients with redundant prepuce underwent operations of degloving circumcision from the base of penis,cut off the extra redundant foreskin of the base of penis,and pay attention to protect the veins under foreskin at the back of penis and foreskin frenulum,thus achieve the goal of curing theredundant prepuce.

在传统术式的基础上进行改良，对52例包皮过长患者采用阴茎根部脱袖状环切术，切除多余的阴茎根部皮肤，保护阴茎背侧静脉及包皮系带，根治包皮过长。

Foliaceous egg form grows to egg shape elliptic, tip blunt needle, the brim has fretsaw to age, base give birth to 3 arteries and veins, luster of face of blade, two sides does not have wool.

叶卵形至卵状长椭圆形，先端钝尖，边缘有细锯齿，基生三出脉，叶面有光泽，两面无毛。5～6月开花，聚伞花序腋生，花小，黄绿色。

With the complex of veins and plexuses anastomosing freely, any laceration of these rather friable structures can lead to considerable blood loss.

由于静脉复合体同盆静脉丛吻合支的存在，这些脆弱结构的任何撕裂都将导致可观的出血。

Leaf blade ovate, base cordate, lateral veins arcuate, often not furcate; fruit cylindric, to 1 cm in diam.

叶片卵形，基部心形，侧脉弧曲，经常不分叉；圆筒状的果，在1厘米直径 39 A。
