摘　　要：二次型理论在经济管理、工程技术等领域有较多应用,其本身在线性代数课程中又是矩阵理论的应用,教学中应予以重视。本文结合教学实践,探讨二次型教学中需突出的重点。Real quadratic form have many applications in the field of economic management,engineeringtechnology,and it is also the application of matrix theory in turn. We should pay attention to it. Combining teachingpractice,three key aspects of real quadratic formare discussed in this paper.
