摘要
本文通过对实践中的一次硬盘空间分配策略的分析，建立了该分配策略的两个数学模型。通过这两个数学模型的求解，解释了这种分配策略的合理性，同时，两个数学模型的提出，为同类问题的解决提供了一种方法。
By analysing the distributive tactics to harddisk space, this paper set up two mathematical models about it. And by finding the solution to those modles, the paper explains the reasonableness of the tactics. at the same time, the raising of the two modles provides a solution to problems of the same kind.
