In this paper, the author further reveals some intrinsic properties of the Cantor set. By erties, the author gives a new method for calculating the exact value of the Hausdorff measure of the C and shows the facts that each covering which consists of basic intervals, in which any basic interval can pletely contain the other, is the best covering of the Cantor set, and the Hausdorff measure of the Cant be determined by coverings which only consist of basic intervals.
