摘　　要：与曲线的弧长对应,提出了E3中曲线的弧角概念。弧角可以作为三维线状物体或对象总弯曲程度的评价指标,特别是由其可以导出道路的角度路程概念,显示了其潜在的应用价值。Corresponding to arclength of curves, the concept of arcangle of curves in E3 is proposed. Arcangle of curves can be used as the index of evaluating the total curvature of wirelike objects;especially it can induce the concept of angular distance traveled of paths, which shows its potential application value.
