【摘要】 对抢渡长江的问题通过合理假设、数学推理并运用物理学知识建立一个寻求抢渡的数学的模型。在分析方法上,对不同的水流分布进行研究,适当简化,用Mathematica软件求其数值解,其结果与实际数据吻合得较好。更多还原

【Abstract】 About speeding the Yangtze River by reasonable assumption,mathenatics reasoning and using physics knowledge the mathematical model is set up, if we analyse the different distribution of water currents, and simplify prorerly, and figure out its result with mathemaitical software, the result just tallies with the real data.更多还原
