| 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. |
