摘 要: 研究了比自相似集更广泛的一类分形集———s_集。利用Vitali覆盖定理得到了由Hs_几乎处处覆盖所描述的s_集的Hausdorff测度的一个基本性质;作为应用,得到了s_集的Hausdorff测度与Hausdorff容度相等的充分必要条件。此外,还给出了s_集存在最好Hs_几乎处处覆盖的一个充分条件。 The s_sets are studied. By using the Vitali Covering Theorem, a basic property describing the Hausdorff measure of the s_set by the notation of H^s_ a\^e\^ covering is obtained. As applications, some sufficient and necessary conditions under which the Hausdorff measure of the s_set equals its Hausdorff content are obtained. In addition, a sufficient condition under which the s_set has an H^s_ a\^e\^ covering is obtained.
