摘　　要：讨论两直线方程一个为对称式方程另一个为一般方程时异面的充要条件以及两异面直线间的距离,利用向量运算的性质,给出了两异面直线间的一个新的距离公式.The necessary and sufficient condition of two lines in space being non-coplanar and the distance be-tween those two lines are discussed when the one of two lines is of symmetric equation and the other general .By the use of vector operation , the corresponding conclusions are obtained and a new formula for calculating the distance between two non-coplanar lines deduced .
