isometry

核心释义

A distance-preserving mapping between metric spaces, typically one-to-one.

1. 1.

   度量空间之间保持距离的函数,即两像的距离等于原像的距离

   A function between metric spaces (or on a single metric space) having the property that the distance between two images is equal to the distance between their preimages.

2. 2.

   生长中的生物体不同部分的生长速率相同

   the growth rates in different parts of a growing organism are the same

3. 3.

   保持每对点之间距离的一个度量空间到另一个度量空间的一对一映射

   a one-to-one mapping of one metric space into another metric space that preserves the distances between each pair of points

4. 4.

   海拔高度相等

   equality of elevation above sea level

等速生长；海拔相等；度量空间之间保持距离的函数,即两像的距离等于原像的距离；生长中的生物体不同部分的生长速率相同；保持每对点之间距离的一个度量空间到另一个度量空间的一对一映射
