论文摘要
引入了欧几里得空间中额叶的概念，并研究了正面和动力学方面的正常和切线图。此外，我们观察到，切线图与正面曲线的相似之处相当于在某些自然条件下额叶曲线的切线图。
The notion of frontals in Euclidean space is introduced and the normal and tangent maps to frontals are studied for both geometrical and dynamical aspects of frontals. Moreover we observe that parallels of the tangent map to a frontal curve is right equivalent to the tangent map of a frontal curve under some natural conditions.
