1. I told everyone who was ready to listen that I had material with pentagonal symmetry. 我曾跟愿意聆听(我的发现)的人说,我找到了五重对称的材料。
2. It offers a PENTAGONAL profile for good bite on the ball resulting in better spin potential. 五角形的结构使其具备良好的咬球性能,提供了绝佳的旋转。
3. Flowers: Sepals strongly ascending to appressed, longest 4 – 5 mm, corolla globose-urceolate, pentagonal, to 10 x 8 mm in diameter, petals apiculate, orange -red. 花:萼片紧密贴合在花上,最长约4-5毫米,花冠球瓮形,(正面观)五边形,10×8毫米直径,花瓣尖细,橘红色。
4. The results of the simulation indicate:compared with cyclone in other domain, the secondary flow of the preheating cyclone with pentagonal inlet and three core volute structure is relatively weaker. 模拟计算结果表明:与其他领域应用的旋风分离器相比,五边形入口、三心大涡壳式旋风预热器内筒入口附近次级流动相对较弱;
