摘　　要：根据正交曲线坐标系和直角坐标系单位矢量之间的变换关系,利用直角坐标系中单位矢量的常矢量特性,严格推导出4种基础正交曲线坐标系下单位矢量的空间导数。Based on the transformation of the unit vectors between the orthogonal curvilinear coordinate system and the Cartesian coordinate system,the spatial derivatives of the unit vectors under four basic orthogonal curvilinear coordinates are derived strictly by using the constant vector property of the unit vector in the Cartesian coordinate system.

关 键 词：正交曲线坐标系 椭圆柱坐标系 单位矢量 空间导数
