摘要
文[1]将射影几何著名的Desargues透视三点形定理推广到三维射影空间P3的四面体和完全n点形（体）中，本文将该定理进一步推广到P3的三面（三棱）锥面、完全n（n≥3）面锥面和完全n棱锥面中。
The famous Desatgues Theorem of perspective three point-shape of projective geometry was extended to tetrahedroid and complete n-point-shape (n≥4) of triaxial projective space p3in the paper [1]. This paper further extends this theorem into trihedonr (triedge)- cone, complete n-hedron-cone(n≥3) and complete n-edge-cone in p3.
