根据该领域近期进展，介绍分形理论在腐蚀行为描述及腐蚀 模型研究等领域的应用.具体分析了一些成功的事例，包括用分维值修正腐蚀波动性指标(如 标准偏差)，以便更好地描述腐蚀行为；观察腐蚀表面分形特征，如早期大气腐蚀中微 液滴尺寸分布和腐蚀表面坑直径及深度分布，并获取分布分维指标；提出腐蚀图像分维的新 计算法，并发现其二维分维D2D和三维分维D3D分别代表表面坑直径及深度的分 布分维；建立基于分形动力学过程的腐蚀模型，预测金属在大气及土壤中的腐蚀发展，并揭 示了分形模型和经验模型之间的参数关联.
Applications of fractal theory in describing corrosion behaviors and creating co rrosion model were introduced based on the recent progresses in the field.Severa l successful samples were demonstrated in details,namely：(1) to correct the ind ex denoting corrosion fluctuation(e.g.,standard deviation)by fractal dimension ( FD) to better describing corrosion behaviors；(2) to observe fractal characteris tics on corroded steel surface (e.g.，distribution for micro-droplet formation i n early atmosphere and for pit diameter and depth in soil corrosion) and obtain distribution FD；(3) to propose a new approach to estimate 2-dimension FD(D2 D) and 3-dimension FD(D3D) of corrosion image and find that they respect ively denoted FD for pit diameter and depth distribution；(4) to create corrosio n formation model based on fractal dynamic process to predict corrosion developi ng of metals in soil and atmosphere，and display the parameter-relation between fractal model and experimental model.
