无特征的

In application point of view, is a bridge between CAD and CAPP, furthermore, it is also a good connecter of geometry topology information of CAD and special engineering information to improve the utility of CAD, CAPP and CAM and to make new sense for parts CAD module, from combination of geometry topology information to special engineering information.

特征不仅仅是连接CAD与CAPP、CAM等领域的一个桥梁，更重要的是它可将CAD中的几何拓扑信息与具体的工程信息紧密地连接起来，提高了CAD、CAPP、CAM等的实际应用成熟度，使得产品模型由原始无工程意义的几何拓扑信息组合变为具有工程意义的特征信息组合。

Point clouds are discrete data points without the topology relationship between them. So, to facilitate and expedite the extraction of contour points for the late NPR style, firstly we should simplify the point cloud data. In other words, non-contour points should be eliminated but their contour points and feature points should be retained .

点云数据本身是无拓扑关系的离散数据点集，所以，为了方便和加速后期非真实感绘制风格化所需轮廓点的提取，首先对点云数据进行了"粗略"地简化处理，即剔除点云数据中非轮廓点保留了其轮廓点和特征点；然后应用判定准则提取出所表示物体的轮廓点并对其进行"归并"形成便于NPR风格化处理的特征轮廓线；最后再对得到的轮廓线进行NPR风格化效果"加密"处理。

The size and localization of oil cells in the leaves, combined with the thickness of leaves, the number of layer of palisade tissue, the ratio of the thickness of palisade tissue to that of spongy tissue, the hypoderm, and the type of hairs, may be used as the identification characteristics of the generas, and even species.

木兰科植物油细胞的分布及其大小与叶厚、栅栏组织层数、栅栏组织与海绵组织厚度间的比值以及下皮层的有无、表皮毛的类型、叶脉的结构等特征相结合，可作为该科中属、甚至种的鉴别特征。

Two hysteretic models suitable for damaged and undamaged fiber-reinforced prestressed wide-beam frames were proposed sequentially. The hysteretic models consisted of a skeleton curves which based on the concept of three stage polygonal line with soften region and some hysteretic rules.

在上述研究的基础上，分析了无损伤和地震损伤的钢纤维预应力扁梁框架滞回曲线的主要特征，进而分别提出了适合于无损伤和地震损伤的钢纤维无粘结预应力扁梁框架结构的恢复力模型。

The local statistical information has a quantization error greater than the local optimal features, but its accuracy is higher.

这些结论为采用无监督聚类方法来发现云型模式并找到最佳的特征和较好的相似性度量以取得更好的结果提供了重要的参考，也有助于避免目前云图自动化分析研究中对特征和度量选取的随意性。

Methods:a total of 50 patients of manic with agressive behavor and 50 patients with no agressive behavor were compaired with their rebation data.results: the two groups were signifcent different in brms and the dinical charaters.imply that the active,agression factor,dinical character of agressive history,irritably of brms were the agressive behavor danger factors.conclusions: to give nurse intervene and heath cducation in manic with agressive behavor early could decrease the agessive behavor mostly.

采用对照分析法，对50例有攻击行为的躁狂症患者和50例无攻击行为的躁狂症患者的相关资料进行分析和显著性检验。结果：两组躁狂症患者在brms和临床特征上存在显著差异，提示brms的动作活动、敌意因子分和临床特征中既往有攻击史，易激惹、不合作及医护人员的强制手段是躁狂症患者的攻击行为的危险因素。结论：及早对躁狂症攻击行为患者实施心理干预及健康指导，可以将攻击行为减少到最低限度。

There is usually little or no progression, the EMG shows non-specific myopathic features and serum CK is normal or only slightly raised.1 The muscle biopsy may show characteristic ultrastructural abnormalities but these can be difficult to detect without specific histochemistry and/or electron microscopy that were not available in 1981 when our patient was biopsied.

经常表现为缓慢或者无明显进展，EMG提示非特异性肌源性改变特征，血清CK是正常的或者仅仅轻微的升高。肌肉活检可能表现为特征性的超微结构异常，但是这些改变必须通过特异性的组织化学和/或电镜才能观察。而在患者进行活检时的1981年这些手段是达不到的。

The results showed that the plant had the character of damp-inhabiting, the cutical on the epidermis of stem and leaf is rather thin but without wax-layer, its stomata protrude clearly on the lower surface of leaf, the rate of palisade parenchyma and spongy parenchyma is rather low and the cortex is well developed in root.

结果表明蓝靛果具有明显的湿生特征：茎、叶表皮的角质层薄，无蜡被；叶片上表皮细胞甚大，无气孔，下表皮细胞小，气孔明显突起；叶脉导管直径小，壁薄；叶肉栅栏组织/海绵组织小；根的皮层发达，富细胞间隙。

Karyotypes of root tip chromosome showed that the arm volume ratio, the mean relative volume and idiogram were identical before and after improving seed vigor, so the pattern of chromosome did not change. But we couldnt confirm whether the pattern of other separation dates and the inner structure varied in this experiment, such as gene mutation.

根尖染色体核型分析结果，甘蓝种子在活力提高前后染色体的臂比值相同，相对长度相同，表明活力提高后染色体在形态及核型上无明显变化，而对于除中期外的其它分裂期染色体的形态特征以及染色体内部结构有无明显变异在本试验条件下尚不能确定。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
