摘　　要：主要研究三维Minkowski空间中非类光曲线的从切高斯曲面的奇点,并且建立了奇点和曲线几何不变量之间的联系,其中曲线几何不变量与曲线同螺线切触的阶数密切相关.In this paper we study the singularities of the rectifying Gaussian surface of a nonlightlike curve in Minkowski 3-space. Moreover we establish the relationships between the singularities of these subjects and the geometric invariants of curves which are deeply related to the order of contact with helices.
