摘要
利用克莱姆法则,给出了异面直线公垂线的一般方程并证明了其正确性,并举例说明其应用.同时给出了异面直线公垂线长的计算方法.
Using Cramer＇s law, a general equation for the common perpendicular line of two skew lines is produced, with its validity proven to be true. And some examples are presented to illustrate its applications. Meanwhile, a method is given to calculate the length of the common perpendicular line of two skew lines.
