摘　　要：曲线的挠率和曲面的第Ⅰ、Ⅱ基本量在微分几何中占有重要的地位,本文简单陈述了曲面上非直线的渐近曲线的挠率与第Ⅰ、Ⅱ基本量的关系．The deflectional curvature of the curve and the first and second foundation measure of the surface are very important in the differential geometry. This paper simply describes the relationship between the defiectional curvature of the non - straight gradual - approach curve and the first and second foundation measure in the surface.

关 键 词：渐近曲线 挠率 第Ⅰ、Ⅱ基本量
