Generative flow velocity to non\|uniform sediment expressed by the common tangential angle;
以公切角表征的非均匀沙起动流速
A New Fixed Method of Common Tangent Point of Biarc Curves;
本文提出了数控加工技术中双圆弧插补的一种新方法:公切点选取不是从几何出发而是从最省材料的物理角度来考虑,并直接首次给出了满足工程设计要求的计算公式而无需迭代,还首次给出了工程设计点的概念。
An optimal algorithm for finding the internal common tangent of two simple planarpolygons is proposed.
提出了一种确定两简单平面多边形内公切线的最优算法。
We put forward in this article the method of applying common tangent circle drawing to draw ellipses.
提出应用公切圆法画椭圆,可不必推平行线和多次加长圆规,只需用直线尺作图,且理论上误差为零。
