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。

Seed cones borne in groups of 1-6, globose or subglobose, 0.9-1.6(-2.5)× 1-2(-2.5) cm; cone scales 20-30, proximal 2 margins often convex in outline, or all 4 margins ± concave in outline, middle part with or without distinct shoulders at widest point, apex usually recurved, umbo rhombic, distally with 4 or 5(-7) toothlike projections 1-3.5 mm. Seeds 2-5 per cone scale, brown or dark brown, irregularly ellipsoid or multiangular and ± compressed, 4-6.5 × 2-3.5 mm; wings 0.2-0.25 mm wide.

1-6个中的成群忍受的球果，球状或近球状， 0.9-1.6(-2.5)* 1-2(-2.5)厘米；珠鳞20-30，轮廓的下部的2个边缘通常凸面，轮廓的或全部4个边缘多少凹面，有或没有在宽点的离生的肩的中部，先端通常下弯，鳞脐，上部每珠鳞具4或5(-7)种子2-5 1-3.5毫米的齿状预测， 4-6.5 * 2-3.5 毫米；翅0.2-0.25毫米宽。

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。

Shrubs or small trees; flowers emerging from lateral, dwarf branches on second year's growth; perianth membranous, with a winged appendage in fruit; utricle slightly concave; disk inconspicuous.

灌木或小乔木；在秒从侧，矮小的分枝出现的花年的发展；膜的花被，有一翅状附属物在果期；胞果稍凹；花盘不明显。 31 Haloxylon 琐琐属

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。
