摘　　要：数学教学中立体几何的证明问题是非常抽象的,也是立体几何证明的难点所在,本文的研究属于应用对策研究,旨在通过转化、引入向量和球面坐标变换等数学工具,对立体几何空间问题代数化,从而提出简化立体几何问题的策略。这就为学习立体几何增添了一个有力工具,从而大大降低了学习立体几何的难度。The teaching of mathematics in the problem of three-dimensional geometric proof is very abstract, three-dimensional geometry is alao difficult to prove. The research of this article belongs to studying applications countermeasures, through transformation, and the introduction of vector spherical coordinate transformation, and other mathematical tools, space Algebra problems of three-dimensional geometry, thus simplifying the threedimensional geometry. This study adds a powerful tool of three-dimensional geometry, which greatly reduces the difficulty of learning three-dlmensional geometry.
