中文摘要：

gibbsites 从苛性的铝酸盐答案在上被猛抛的种子的不规则的表面，根据分数维的理论被调查。二种分数维的尺寸被用来描绘这些不规则。盒子尺寸并且光谱尺寸分别地基于种子的 SEM 图象和降水的散开的动态方程。两种这二尺寸被反应温度影响，与条件和罐头反映的不同反应演变降水率上的种子的不规则的影响。Boxdimension 为种子的不规则的形态学的描述是合适的，当时光谱尺寸能解释分数维的动态行为。

英文摘要：

The irregular surface of seeds on which gibbsites are precipitated from caustic aluminate solutions, was investigated according to the fractal theory. Two kinds of fractal dimensions were used to characterize these irregularity. Box-dimension and spectral dimension are based on the SEM images of seeds and diffusive dynamic equation of the precipitation respectively. Both these two dimensions are affected by the reaction temperature, evolved with different reaction conditions and can reflect the influence of irregularity of seeds on the precipitation rate. Box dimension is fit for the characterization of the irregular morphology of seeds, while spectral dimension can explain the fractal dynamic behavior.
