摘要
讨论了一般异面直线的相交直线存在及唯一存在的充要条件,证明了两者的等价性,并在唯一存在时给出了一般的表达式.
The full and necessary conditions that the intersection line with general straight lines in different planes existed and existed solely was discussed. Their equivalent relation was proved. And the general expression of the intersection line with the sole existence was gaved.
