通过电沉积二维地生长锌金属叶。这些结构清楚地提醒我们，根据Witten-Sander扩散限制聚集模型，计算机模拟的随机模式。尺度不变性是通过计算密度密度相关函数的数字化图案的照片。在许多例子中平均的Hausdorff维数为D= 1.66±0.03，这与二维扩散限制聚集模型（D = 5.3）非常一致。
Zinc metal leaves are grown two-dimensionally by electrodeposition. The structures clearly remind us of the random patterns simulated by computer according to the Witten-Sander diffusion-limited-aggregation model. The scale invariance is tested by computing the density-density correlation function for the digitized patterns of the photographs. The Hausdorff dimension averaged over many examples is D= 1.66±0.03, which is in excellent agreement with that of the two-dimensional diffusion-limited-aggregation model (D≅ 5 3).
