摘要
本文给出了广义二次型的概念 ,并用数学分析的方法研究了它的标准形的存在性及唯一性 。
The concept of extended quadratic form is supposed and the existence and uniqueness of its canonical form are studied on method of analysis of mathematics. At the meantime, the method for obtaining the orthogonal transformation matrix which is needed while the extended quadratic form is changed into its canonical form is given in this paper.
