1、作最后冲刺。(3)根据艇速趋势线，参考桨频趋势线，本文把200m短距离项目划分为三个阶段：起航加速划阶段(O一50m分段)、途中划阶段(50-190m分段)、冲刺划阶段(190-200m分段)。(4)对每lOm分段艇速和桨频进行K型聚类，各类型间的距离差异概率均值均小于0．001，聚类效果好，原有的艇速和桨频各42类聚合成各2类。具体各项目艇速和桨频类型：MKl—200m和MK2-200m项目为艇速的类型一+桨频的类型一；WKl-200m项目为艇速的类型二+桨频的类型一；MCl-200m项目为艇速的类型二+桨频的类型二。关键词：200m；皮艇；划艇；起航技术；竞赛策略III，▲T艇ST切DYO
