| 摘 要： | 人在外出行走时被淋雨，应该如何选择行走速度使得淋雨量最小，这个问题一直引起人们的兴趣，也有很多学者通过建立数学模型给予解答．一些文献给出了直观简单并具有创新性的思维方法，但也分别存在一定的缺点．通过适当采用并修正、补充参考文献中的方法，糅合这些方法的优点，弥补其不足，利用三维角度和单调性分析对淋雨量问题给出更加严谨的解答，并经过Matlab软件进行更深层次的分析，得出有价值的结论．

| Abstract: | When people walk in rain, the problem of at what speed they have the minimum of rain falling on them arouses people＇s interest.Many scholars have tried to give the solution by building a mathematic model. Some references offer straightforward and innovative ways, but those ways have some shortcomings respectively. Through adopting, correcting and supplementing the ways in the references, this paper combines the advantages and compensates for the weaknesses. It gives more rigorous solutions to the problem of rain amount through three-dimension and monotonicity analyses, and makes deeper analyses by using Matlab to arrive at valuable conclusions. |
