Oval 鹅蛋形
(重定向自Egg shaped)
An oval (from Latin ovum, "egg") is a closed curve in a plane which "loosely" resembles the outline of an egg. The term is not very specific, but in some areas (projective geometry, technical drawing, etc.) it is given a more precise definition, which may include either one or two axes of symmetry.
In common English, the term is used in a broader sense: any shape which reminds one of an egg.
