By using the molecular dynamics theory and diffusion limited aggregation model of film growth, the fractal phenomenon of the nodule nucleation was well explained.

用分子动力学和薄膜生长的扩散限制聚集模型，薄膜中结瘤微缺陷成核时的分形现象得到了很好的解释。

Compared with conventional method and the diffusion limited volatiles combustion (DLVC) model, the results predicted by MFFVC agree well with those by the developed continuous-film model.

与挥发分现有计算方法、扩散控制的挥发分燃烧(DLVC)模型相比，MFFVC模型预报与考虑热解的扩展连续膜模型符合较好。

Results from our model revealed that oxygen uptake by diffusion from the air, under normal conditions, was limited to the out most layer of the skin and did not penetrate beyond the germinal layer.

研究结果表明，在正常生理条件下，皮肤从空气中通过扩散输运所获取的氧仅限于表皮角化层，而不能到达表皮生发层。
