ascending angle meaning in English
爬坡角
上升角
Examples
- Since complicated differential and integral operations were involved in the kernel of the integral equation , we simplified the equation and got the nakano equation . as instances , the planar archimedean spiral antenna , the planar equiangular spiral antenna , the monofilar helical antenna , the conical helical antenna with fixed ascending angle and the conical equiangular - spiral antenna were analyzed through the moment method . all of the results matched fairly well with the references and experiment results
这种方法的积分方程的积分核里含有复杂的微积分运算，为了简化计算，本文在推广的海伦积分方程的基础上，对方程进行了简化，推导了nakano方程，并以平面阿基米德螺旋天线，平面等角螺旋天线，轴向模圆柱螺旋天线，具有固定升角的圆锥螺旋天线和圆锥等角螺旋天线为例，用矩量法求解了天线上的电流分布，研究了螺旋天线辐射的宽频带特性，所得的结果均与参考文献吻合很好。 - Based on ansys , this paper studies stress concentration on single notch of eight kinds of high strength bolts used in grid structure , obtaining their stress concentration coefficients , discussing the effect of ascending angle , bottom radius of screw thread and bolt - ball on stress concentration , introducing their effect coefficients of a1 , a2 , a3 , putting forward the formulae of stress concentration coefficient
本文以ansys有限元软件为研究手段，针对网架螺栓球节点的8种螺栓规格进行单缺口应力集中分析，定量求得相应的应力集中系数k _ t ；论述了螺纹升角、螺纹牙根圆角半径r及球栓直径比d / d对k _ t的影响，并引入相应的影响系数_ 1 、 _ 2及_ 3 ，最终提出了应力集中系数k的计算公式。
