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。

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。

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。

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；
