线线共面条件及其平面方程的求法

Two Coplanar Lines and the Solution of Its Plane Equation

空间任意两个向量都是共面的,但是空间任意两条直线却不一定共面。研究给出了线线共面的条件并加以了证明,从而得出了线线共面平面方程的求法。

Any two vectors in space are coplanar,but any two lines in space are not necessarily coplanar.In this paper,the coplanar condition of two lines is given and proved,thus the coplanar condition of two lines and the solution of their plane equations are obtained.
