The results show that monthly rain acidity series exhibit fractal Brown motion with Hurst exponent H> 0.

表明其变化表现为分形布朗运动，各月份降水酸度值是相互关联的。

By taking the image to be compressed as a grey-level surface of some fractal brown motion, the fractal dimension of this surface gives out a good description of its texture characteristics.

把灰度图像看作是某种分数布朗运动形成的(分形)灰度表面，并用这种灰度表面的分形维数来刻画它的纹理粗糙程度。
