分形生长ＤＬＡ模型的出现，深化了人们对非平衡生长现象的认识，揭示和解决了一些传统方法难以解决的问题．各种改善和修正的ＤＬＡ模型的出现，丰富了人们对ＤＬＡ集团的认识，ＤＬＡ集团不再具有统一的无序分形各向同性的特征，而是和网格及模型有关．在ＤＬＡ模型中考虑粒子吸附几率后，可以反映流体驱替过程中界面张力效应，尤其是可用于模拟流体驱替过程中粘性指进现象的动力学演化过程，为描述粘性指进现象提供了一个新的、有效的手段．
The appearance of fractal growth DLA model deepens people’s understanding of the phenomenon of unbalanced growth and reveals and solves some problems that are difficult to be solved by traditional methods. The emergence of DLA models with various improvements and amendments has enriched people’s understanding of DLA groups. DLA groups no longer have the same characteristics of disordered fractal isotropy but are related to grids and models. Considering the probability of particle adsorption in the DLA model, it can reflect the interfacial tension effect during fluid flooding, especially the dynamic evolution process that can be used to simulate the phenomenon of viscous fingering during fluid flooding, providing a New and effective means.
