抛物面坐标系是一种三维正交坐标系，是二维抛物线坐标系的推广。与大多数的三维正交坐标系的生成方法不同，抛物面坐标系不是由任何二维正交坐标系延伸或旋转生成的。

Paraboloidal coordinates are a three-dimensional orthogonal coordinate system ![(\lambda, \mu, \nu)](/Images/godic/202501/06/b2b4d19d9cb128df05e34eb86a9cce243423.png")
that generalizes the two-dimensional parabolic coordinate system. Similar to the related ellipsoidal coordinates, the paraboloidal coordinate system has orthogonal quadratic coordinate surfaces that are not produced by rotating or projecting any two-dimensional orthogonal coordinate system.
