n.
1.【数学】椭圆,椭圆形。
2.=ellipsis.
a closed plane curve resulting from the intersection of a circular cone and a plane cutting completely through it; "the sums of the distances from the foci to any point on an ellipse is constant"
同义词:oval,

In mathematics, an ellipse (from Greek ?λλειψι? elleipsis, a "falling short") is a plane curve that results from the intersection of a cone by a plane in a way that produces a closed curve. Circles are special cases of ellipses, obtained when the cutting plane is orthogonal to the cone's axis.
