el·lipse AHD[ĭ-lĭpsʹ] D.J.[ɪˈlɪps]K.K.[ɪˈlɪps]n.(名词)The line running through the foci (F and F1) of an ellipse is the major axis. The vertices (V and V1) mark where the major axis intersects the ellipse. The midpoint between the vertices is the center; the line that runs vertically through the center is the minor axis.Clarinda/Academy Artworks- A plane curve, especially:椭圆:一个平面曲线,尤指:
- A conic section whose plane is not parallel to the axis, base, or generatrix of the intersected cone.圆锥的一部分,其切面既不平行于轴和基面,也不平行于圆锥母线
- The locus of points for which the sum of the distances from each point to two fixed points is equal.椭圆:到两定点的距离的和为常数的点的轨道
