查询词典 obtuse triangle

Leaf blade apex obtuse or rarely retuse or mucronate; midvein apically slightly flexuous.

叶片先端钝的或很少微凹的或短尖；中脉顶部稍微曲折。

Petiole long; leaf blade palmately (3--)5--7(--9)-foliolate; petiolules 0.5--2.5 cm; leaflets 3--13 × 0.3--5 cm, subleathery to leathery, abaxially glaucous and densely very minutely papillose, adaxially green and shiny, base cuneate, margin entire, apex acuminate, acute, or obtuse, sometimes emarginate; secondary veins 6--10 pairs, tertiary veinlets and secondary veins conspicuously prominent on both surfaces or abaxially slightly prominent and adaxially inconspicuous.

叶柄长；掌状叶片(3-)5-7(-9)具小叶；小叶柄0.5-2.5厘米；小叶 3-13 * 0.3-5 厘米，近革质的到革质，背面的有白霜和浓密的细小小乳突，次脉6-10 对，第三细脉和次脉显著的两面突出或背面稍突出和正面不明显。

Based on 3D steady and incompressible N-S equation and k-ε turbulent model, the aerodynamic performance of three different design options of 160 km/h container flat wagon was analyzed and compared using finite volume method. The three design options are as follows: the first design option has no headwall and the side surface of side beam is flat; the second and the third both have headwall and high side beam, and the side surface of side beam of the second is obtuse, while the third is cambered.

基于三维、不可压、定常N-S方程和k-ε双方程湍流模型，采用有限体积法对3种不同设计方案在运行时速为160 km/h的集装箱专用平车在有、无横风情况下的气动性能进行分析与比较，其中：方案一的平车无端墙，侧梁侧面平直；方案二和三的平车均加有端墙，且侧梁加高、侧面形状分别为钝形和弧形。
