摘　　要：通过向量在基下的坐标来统一认识点在二维的笛氏直角坐标系、仿射坐标系和射影坐标系下的坐标,从而体现代数和几何的密切联系及代数的高度的抽象性.The coordinates of the points in the two-dimensional Descartes coordinate system,the affine coordinate system and the projective coordinate system are studied through the coordinates of the vector in the bases.The results show the close relation of algebra and geometry and the highly Abstract of algebra.
