摘要
研究了圆、圆球的一组其轭半径在另一组共轭半径上的投影性质。利用仿射变换的原理,证明了有关椭圆、椭球的一组共轭半径在另一组其轭半径上投影的4个性质。
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.
