摘要
本文讨论的是与同一条空间曲线有关的直线族与平面族。虽然这些直线族构成的直纹面及平面族产生的包络是各不相同的,但由于研究方法的适当改进,可以使得它们的一些性质的数学形式,能够统一地表达出来。
This paper discusses the line families and plane families with the same space curve.Though the ruled surface produced by the line families and the envelope produced by the plane families are different, with the research methods improved, some of their properties can be represented with the same kind of mathematical formulas.
