The mathematical model of the hyperboloid twist drill was introduced. 介绍了以旋转单叶双曲面作麻花钻钻尖后刀面的数学模型。
The stress, displacement and modality of the hyperboloidal shell is analysed, with the help of ANSYS9?0. 以配煤仓落料斗为对象,在ANSYS9·平台上对双曲料仓斗壳进行了静载计算和模态分析。
The trajectories of the negative ions in the negative ion atom probe have been calculated for hyperboloidal tip shape. 摘要本文基于双曲而形样品针尖,计算了负离子原子探针中负离子的飞行轨迹。
The authors show that the hyperboloid of one sheet and the hyperbolic paraboloid are ruled surfaces. 作者证实:单叶双曲面和双曲抛物面是直线曲面。
Now there is a hyperboloid, a concave ellipsoidal surface and a convex ellipsoidal surface need to be done. 现在是一个双曲面,一个凹椭球面,一个凸椭球面。
