Aluminum motorcycle left-cover has the features of uniform wall-thickness and large profiledimension.
摩托车铝合金左盖压铸件，壁厚比较均匀。

And then, fractal characterizations and dimension calculations were conducted in two kinds of profile curves with the methods of the structure function and the mean square root.
然后用结构函数和均方根两种方法对理论和实际的轮廓曲线进行了分形表征和分维计算。

Introducing correlation dimension method in the fractal theory and the correlation dimension curve of the synthetic seismic profile is analyzed.
