| Abstract: | The natures of projection of a group of conjugate radiuses of the circle and sphere on other group are studied. Four natures about projection of a group of conjugate radiuses of the ellipse and ellipsoid on other group are proved by the principles of affine transformation. |
| Keywords: | affine transformation ellipse ellipsoid conjugate radius |
