摘要: 利用运动分析和相对运动,分别给出了三角形3个顶点上追击者能够相遇的速度条件.相遇点是三角形的布洛卡点,追击曲线是对数螺旋曲线.

关键词: 追击问题, 相遇点, 极限性质

Abstract: The initial velocity of three chasers which can meet at rendezvous point is derived by analytical motion method and relative motion method.This point is the Brocard one of triangle and the pursuit curve is the logarithmic spiral curve.

Key words: pursuit problem, rendezvous point, limitation propriety
