三元一次方程与空间平面

The Three Equations and Space Plane

数学课程中的方程与空间几何图形比如平面、曲面、直线、曲线是有对应关系的,三元一次方程就与空间几何图形——空间平面相对应。一些特殊的三元一次方程,比如常数项为零、或者只含有两个未知数、或者只含有一个未知数的就会与一些特殊的空间平面相对应。

Equation and the geometric figure in the mathematics curriculum such as flat, curved, straight line, curve has corresponding relationship, with the three equations and geometric figure--space plane corresponding. Some special three equations, such as the constant term is zero, or contains only two unknowns, or contains only one unknown, three equations will be some special space plane corresponding.
