 双曲点 添加此单词到默认生词本
hyperbolic point
neutral point

  1. 作为上述理论的具体应用,研究了准双曲面齿轮传动两齿面之间在给定参考处的法曲率、短程挠率的关系。
    In addition, as an application of the theory mentioned above, the relationships of normal curvature and geodesic torsion between tooth surfaces of hypoid gearing at given reference meshing point are analyzed.
  2. 在三维三分量地震勘探资料处理中,对于反射纵波资料可以采用常规方法进行处理;而对于反射转换波资料,由于其传播路径的非对称性,转换波共中心道集不再是共反射道集,转换波时距方程也不是双曲方程,因此不能采用常规纵波处理方法来处理转换波资料。
    For processing of 3D and 3C seismic data, the reflected P-waves can be processed with the conventional methods, while the reflected converted waves can not be processed with the conventional P-wave processing methods, because their travel paths are asymmetrical, their common midpoint gathers are no longer common reflection point gathers, and their time-distance equation is non hyperbolic.
  3. 摘要对江坪河双曲拱坝进行了三维弹塑性有限元分析,利用有限元应力成果分别计算了正常蓄水位、设计洪水位等3种工况下加固前后坝体坝肩系统的安全系数和7个可能滑动块体的抗滑富余系数。
    For Jiangpinghe Double-Curved Arch Dam, 3-D elasto-plastic FEM is made, in which the point safety factors of the dam-abutments system and the safety margin for coefficients of sliding resistance on 7 potential sliding blocks of the dam before and after the reinforcement of the dam are calculated under the conditions of the normal storage level and the design flood level respectively based on the results from the analysis made with FEM.
