- Conical coordinates, sometimes called sphero-conal or sphero-conical coordinates, are a three-dimensional orthogonal coordinate system consisting of concentric spheres (described by their radius r) and by two families of perpendicular elliptic cones, aligned along the z- and x-axes, respectively. The intersection between one of the cones and the sphere forms a spherical conic. (en)
- 圓錐坐標系（英語：Conical coordinates）是一種三維正交坐標系。它的三個坐標曲面分別為同心圓球面，錐軸為 x-軸的圓錐面，錐軸為 z-軸的圓錐面。 (zh)
