数字黑洞的概率特性初析

The phenomena of dark caves had been studied long ago.However it is scarely on the probabilistic features of dark caves of digits.In this paper the probabilistic feature of dark cave of digits is studied by taking a large sample.We intend to yield its practical application from the obtained result.
