e/Ellipsoidal coordinates

Information
has gloss	eng: Ellipsoidal coordinates are a three-dimensional orthogonal coordinate system (\lambda, \mu, \nu) that generalizes the two-dimensional elliptic coordinate system. Unlike most three-dimensional orthogonal coordinate systems that feature quadratic coordinate surfaces, the ellipsoidal coordinate system is not produced by rotating or projecting any two-dimensional orthogonal coordinate system.
lexicalization	eng: ellipsoidal coordinates
instance of	(noun) a system that uses coordinates to establish position reference system, coordinate system, frame of reference, reference frame

Meaning
Chinese
has gloss	zho: 橢球坐標系是一種三維正交坐標系，是橢圓坐標系的推廣。與大多數的三維正交坐標系的生成方法不同，橢球坐標系不是由任何二維正交坐標系延伸或旋轉生成的。
lexicalization	zho: 橢球坐標系
