Centroid怎么翻译成中文？

@李东岳 在 Centroid怎么翻译成中文 中说：

Centroid

形心吧

[Leon Zhao]

对比一下，感觉密度均匀情况下就是质心和形心吧，如果按照wiki说的，就是几何重心，下面词典里也给了一些使用的例子。

Barycenter 这个呢

@李东岳 在 Centroid怎么翻译成中文 中说：

Barycenter

质心？貌似常用的是center of mass，Barycenter多用于多质心系统，天文学？

[Leon Zhao]

这个应该是单纯指质量的中心，质心了吧@李东岳

[李东岳]

Centroid是形心？
Barycenter是质心？

[Leon Zhao]

@李东岳 差不多是这样的吧，centroid 两者皆可，barycenter 单指质心。看看有没有其他大佬有比较专业的解答吧

[李东岳]

感谢二位大佬

While in geometry the word barycenter is a synonym for centroid, in astrophysics and astronomy, the barycenter is the center of mass of two or more bodies that orbit each other. In physics, the center of mass is the arithmetic mean of all points weighted by the local density or specific weight. If a physical object has uniform density, its center of mass is the same as the centroid of its shape.
