【摘要】 给出了空间曲线段的基于弧长的定比分点公式,从而把直线段的定比分点公式推广到了空间曲线段.特别地,对具有定长切向量的空间曲线段的定比分点进行讨论,得到了很理想的结果.更多还原

【Abstract】 Based on the arc length of a curve,in this paper,a formula of Definite Proportional Devision Point for Space Curve Segment was given,thus generalizing the traditional formula for line segment to space corve segment.Especially,the definite proportional devision point for space corves with tangent vector of constant length were discussed and an ideal result was obtained.更多还原
