摘要
在学习“解析几何”、“画法几何”及“射影几何”等学科的基础上,本文将它们之间做了一些横向的联系。用射影几何的观点、投影的方法、代数的手段,通过对4×4以下矩阵的不同分析,来研究点、线、面的几何问题,给矩阵的秩以具体而多样的几何涵义。
Some connections among the Analytic Geometry,Descriptive Geometry and Projection Geometry were studied.In the view of projection geometry and by the means of projection and algebra,the various detailed geometrical meanings of the order of a matrix were given through analysing the matrix less than 4×4 and studing the geometrical problem of point, line and plane.
