富钴结壳分布的分形特征

PRELIMINARY FRACTAL ANALYSIS OF COBALT RICH CRUST DISTRIBUTION

利用我国在西太平洋国际海底两个海山获得的富钴结壳资料进行分形研究后发现 ,富钴结壳的分布具有变维分形分布的特点 ,结壳丰度呈二阶累计和分形分布 ,结壳厚度呈多阶不定累计和分形分布 ,通过计算得到了它们各自的分维数 。

The variable dimension fractal features of cobalt rich crust are found by analyzing the data of abundance and thickness of cobalt rich crusts from two seamounts located at the international seabed in the West Pacific Ocean.Relative to abundance,crust thickness has a more complex change.Taking seamounts A and B into comparison,the crust abundance of seamount A doesnt have a change as complex as that of seamount B,but the crust thickness changes more complexly than that of seamount B.In other words,crust abundance of seamount A is stable and its crust thickness is unstable,while seamount B is just the opposite.This knowledge is consistent with the result of the actual sampling.The abundance of crusts is in second order cumulative total fractal distribution,and thickness of crusts is in multi order indeterminate cumulative total fractal distribution.Their fractal dimensions have been gotten after calculation.According to this,the preliminary evaluation of crust resource is done.
