矩阵秩在判断平面及直线间相关位置中的应用

The Function of Matrix Order in Judging Plane and Straight Line Relative Position

由线性代数中矩阵秩的理论,给出了解析几何中平面与平面,平面与直线,直线与直线相关位置的判断方法,拓广了矩阵秩理论的应用,简化了平面与直线相关位置的判断方法,强化了代数与几何的联系.

From the matrix order theory of linear algebra, Judging methods of relative positions are given out between plane and plane, plane and straight line, straight line and straight line in analytic geometry.it broadens the application of matrix order theory, simplifies judging methods of the relative positions between the plane and the straight line, strengthens the connections between algebra and geometry.
