抢渡长江数学模型及应用

The Mathematics Modle of Crossing the Yangtze River and Application

抢渡长江是一种很有意义的体育竞技活动 ,由于江水流动对参赛者造成的影响使竞赛更具挑战性及观赏性。本文通过建立抢渡长江的数学模型 ,分析了游泳者应该沿怎样的游泳方向和游泳路线才能更快地到达终点 ,并进一步讨论该模型在横渡长江等其他活动中的应用。

Across the Changjiang River is a meaningful physical training. The influence of the flowing stream on the competitor makes the contest more challengeful. The paper establishes the mathematics modle of crossing the Changjing River,analyses how the swimmer could reach the end-point faster and successfully along the right direction and route.furthermore,discusses the application on the other activity.
