或许对象通过凸集、凸曲线或其它可度量向量空间中的结构来表示会更好。

Perhaps objects might be better represented by convex bodies, curves or by other structures in a metric vector space.

二维和三维的欧几里德空间是度量空间。另外，内乘空间、向量空间以及某些拓扑空间等也都是度量空间。

Two-and threed imensional euclidean spaces are metric spaces as are inner product spaces vector spaces and certain topological spaces.
