Through the analysis of De, an alternative mechanism interpreting of the"overshoot"phenomena can be obtained: when the diffusing time of small molecular penetrants is shorter than relaxation time of the involved polymer, small molecular substance penetrates into the polymer quickly and its concentration reached a maximum, then the swelling of the polymer by the small molecules makes the chain structure of the polymer relaxed, thus the free volume in polymer matrix, which is occupied by small molecule, decreased, and will squeeze part of the small molecular substance out of the polymer, and therefore overshoot behavior can be observed.

通过对De的分析，可以得出产生&超调&现象的机理的另一种解释：小分子渗透物质的扩散时间相对于聚合物的松弛时间要短（相当于有个更快的扩散速度），所以小分子迅速扩散进聚合物中达到一个极值，由于小分子物质对聚合物的溶胀，使得聚合物链结构产生松弛，由于聚合物链结构的变化，小分子物质占有的自由体积会减小，这样会挤出小分子物质，使得小分子物质在聚合物中的浓度减小，如果高聚物粘弹性明显，甚至可能出现多个浓度的衰减振荡并达到平衡值。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
