isometry 是什么意思

中文翻译与英英解释

	n. 1.度量相等。 2.【地质学；地理学】等高。

	equality of measure (e.g., equality of height above sea level or equality of loudness etc.)
	equality of elevation above sea level
	a one-to-one mapping of one metric space into another metric space that preserves the distances between each pair of points; "the isometries of the cube"
	the growth rates in different parts of a growing organism are the same

In mathematics, an isometry is a distance-preserving map between metric spaces. Given a metric space, or a set and scheme for assigning distances between elements of the set, an isometry is a transformation which maps elements to another metric space such that the the distance between the elements in the new metric space is equal to the distance between the elements in the original metric space.
