摘　　要：提出了二次曲线的伴随直线的概念,从它与二次曲线的相关位置关系出发,利用解析方法证明了伴随直线的几个性质,为二次曲线的相关理论研究带来方便.In this paper, a concept of adjoint line of non-degenerate quadratic curve was put forward. According to the relative position between the adjoint line and quadratic curve, some properties of adjoint line were obtained by the analytical methods, which brings convenience for the research to relative theories of quadratic curve.
