In this paper,we study the problem finding basic circle in plane graph,in which the number and coordinate of nodes and the node number of two ends of the side is given,we create a method,which is enlightened by the"proble of find way in labyrinth",to find way in branch point and then to find basic circle.

论文讨论了平面图形中存在着节点和边，在已知节点的坐标、标号以及边的标号和边两端的节点标号情况下，对其中存在的一阶环进行计算机搜索问题，提出了受"走迷宫"问题启发的一种在分叉点沿一定的方向进行搜索的方法。

The preliminary results show that the maximally evoked responses are at a deeper layer of the cortex. The value of this depth form surface of the cortex is about 900 m. A twodimensional recording was performed at this depth to find the responsive center or locus. The result shows that a dipole can be used to represent the responsive center with a coordinate of 1.9 mm posterial and 1.9 mm lateral to the Bregma. These finds should be valuable for further studies about pain.
