摘　　要：介绍了BESⅢ漂移室单元结构的设计和丝层安排,讨论了如何设置斜丝倾斜角以及直、斜丝交界处存在的问题,并通过对漂移时间与距离关系的模拟优化了漂移室丝层半径.Design of cell structure and layer arrangement of the BESⅢ drift chamber are presented. The effect of stereo angles and the layers at axial-stereo boundaries on the drift-time-to-distance relation are discussed. In addition, the optimization of layer radius is performed based on the drift-time-to-distance relation.
