查询词典 concave

Based on the transfinite interpolation theory, an improved algebraic grid generation method is presented in this paper. Our improvements of existing algebraic grid generation method include:(1) orthogonality control, which greatly improves grid orthogonality adapted to viscous flow calculation;(2) weighted average smoothing, which efficiently handles with grid intersection due to concave corner existence;(3) normal vector control, which adjusts grid smoothing near convex corner.

基于无限插值理论，引入本文提出的网格正交控制、物面法向量控制、加权平均光顺措施，给出了一种改进的空间网格生成方法，有效克服了传统无限插值网格生成方法在复杂外形网格生成方面的缺陷，有效改善了网格的法向疏密性、贴体性及周向网格的均匀性，对真实飞行器部件网格生成非常迅速。

In addition, pairs of birds Mohist shadow, the umbra and penumbra objects, concave and convex imaging phenomena, are also made many studies.

此外，墨家对飞鸟的影子、物体的本影和半影、凹面镜和凸面镜的成像现象等，也都作了许多研究。

If the dial indicator reads 0.14~0.3mm , it means the tooth clearance is right; You can also use a 15~20mm long and 0.5mm thick lead sheet or "∽"-shaped fuse . Put the sheet or fuse between the unengaged tooth flanks tha is between the convex surface of small bevel gear and the concave surface of the large bevel gear. Turn the gear, then the pressed thickness of the big lead sheet end suggests the normal tooth clearance of this site.

另一种方法是用长15~20毫米，厚0.5毫米的铅片或弯成"∽"形的保险丝，放入两齿轮非啮合的齿面之间（即小锥齿轮的凸面和大锥齿轮的凹面之间），转动齿轮，则铅片在靠近大端处被挤压的厚度即为该处的法向齿侧间隙。

Utricle hemispheric, apically slightly concave; pericarp fleshy, adnate to seed.

胞果半球形，顶部有点凹；肉的果皮，贴生于结子。

Seed ± globose, usually somewhat concave ventrally, without endosperm.

种子多少球状，通常有点凹的腹，没有胚乳。

IAs to the uniformity of MAO Coatings and efficiency of MAO Process, assumption aboat breakdown was brought up. From microcosmic viewpoint, the Al_2O_3/Al interface was accidented. Because of skin effect, protuberant region is electric-charge-rich (electron-pool) region and concave region electric-charge-pool (electron-rich) region at the anode-positive-loaded half cycle.

对微弧氧化的击穿放电机制，提出了一种基于趋肤效应的假设：氧化膜和铝基体的界面凹凸不平，在微观上有许多尖端和凹区，由于电荷在铝表面有趋肤效应，尖端形成富电荷区而微观凹区形成贫电荷区。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
