异面直线【skew line】
专业英文释义：
In geometry,two lines are said to be skew lines if they do not intersect but are not parallel.
Skew lines only exist in three or more dimensions; any two lines in the plane which are not parallel must intersect at some point.In fact,two lines are skew lines if and only if they do not lie in a single plane together.This means that if each line is defined by two points,these four points must not be coplanar; put another way,they must be the vertices of a tetrahedron of nonzero volume.Any three of them will still be coplanar,since three points define a plane,but no three points will be collinear,since this would make all four points coplanar.
再问： 可以帮我翻译下面的话吗?论文的摘要，谢谢！ “在了解如何判断两直线异面的基础上，对异面直线公垂线的求法的讲解以及公垂线方程的推导，最后利用公垂线段的直接求法、等积法、向量法、最值法、公式法等多种方法对异面直线的距离的求解，将空间立体几何中异面直线的距离的求解这样一个较困难的问题转化为简单的问题．”
再答： Based on the knowledge of methods of estimating skew lines, this paper gives an introduction of solution to common normal and deduction of the fomula, and solves the distance of skew lines with direct method, product method, vector method, maximum/ minimum method, formula method and so on. Therefore, the difficult problem about the distance of skew lines in solid geometry could as thus be transformed into an relatively simple problem.
