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.

谷歌的网页级别是特征向量中心性度量的一个变体。

Google's PageRank is a variant of the Eigenvector centrality measure.

从另一方面来看，“通量”度量的是，沿着曲线前进时，大致会有多少向量场通过曲线。

Flux, on the other hand, measures, when I go along the curve, roughly how much the field is going to across the curve.
