拓扑学的英文名是Topology,直译是地志学,也就是和研究地形、地貌相类似的有关学科．它是几何学的一个分支,但是这种几何学又和通常的平面几何、立体几何不同．通常的平面几何或立体几何研究的对象是点、线、面之间的位置关系以及它们的度量 The English name of Topology is Topology. The literal translation is geo-histology, which is similar to the study of topography and geomorphology. It is a branch of geometry, but this geometry is different from the usual plane geometry and solid geometry. The objects of general plane geometry or solid geometry study are the positional relationships between points, lines, and surfaces and their metrics.
