1. The torque force section is changed to a regular hexagonal prism from a regular quadrangular prism. 是以由引入段、切削段、锥杆段和扭力段组成的丝锥组成的。
2. The roof of the natatorium of Chongqing adopts quadrangular pyramid with welding hollow sphere joints. 重庆市游泳、跳水馆屋盖设计采用四角锥焊接空心球节点钢管网壳。
3. A new algorithm was proposed to partition triangular meshes into quadrangular segmentation automatically. 提出了一种对三角网格模型进行自动四边区域划分的算法。
4. The dynamical analysis of quadrangular pyramid grid structure modality and seismic response is made by ANSYS. 利用ANSYS作出了某四角锥网架的模态及地震响应的动力分析。
5. Additionally, compared with the quadrangular slice, the width of triangular slice has a greater influence on the calculation speed of landslides. 另外,与四边形条块相比,三角形条块宽度的大小对滑坡速度计算影响较大。
