摘　　要：本文运用类比方法,在立体几何中,导出了三棱台的一个分割定理及其推论和推广。作为一种教学实践活动,在此试图展现类比过程的思维活动及探索的方向,以期对数学教学工作有所帮助。By analogism, this thesis gives a theorem of cut in the frustum of a triangular pyramid and its inference and extension in the solid geometry. We will here try to present a thinking way and considering proceeding about analogism in mathematical teaching and hope that it will be helpful to our mathematical teaching later.
