摘要
针对二次型的综合性和抽象性,利用二次型的几何意义首先阐述二次型的标准形所表示的图形,进而得出二次型的本质,建立二次型的直观概念。
According to the comprehensiveness and abstractness of quadratic forms,we first elaborate graphics of the canonical forms of quadratic forms by the geometric significance,then come to the essence of quadratic forms,and establish the visual concepts of quadratic forms.
