中文摘要：

研究几类模糊空间关系。作为分明的RCC8拓扑关系的推广，给出R-正则开的模糊集、R-正则闭的模糊集、R-开的模糊集以及R-闭的模糊集的模糊RCC8刻画。这些模糊空间关系将会有助于对模糊空间区域进行定性的推理研究。

英文摘要：

This paper investigate several kinds of fuzzy spatial relations. As for a generalization of crisp RCC8 topological relations, This paper give characterizations of fuzzy RCC8 topological relations for R-regular open fuzzy sets, R-regular closed fuzzy sets, R-open fuzzy sets and R-closed fuzzy sets respectively. The results are useful for qualitative fuzzy spatial reasoning.
