摘要: 由不同正交曲线坐标系的单位基矢之间的变换矩阵,推导出正交曲线坐标系的单位基矢对本身坐标的求导和对时间的求导规律.并且以球坐标系与柱坐标系的单位基矢的本身空间坐标求导为例进行了讨论.
关键词: 正交曲线坐标系, 幺正矩阵, 单位基矢, 导数
Abstract: Though the transformation matrix between the unit basic vector in deferent orthogonal curvilinear coordinate system, we deduce the law of the unit basic vectors derivative of their own coordinates and the time in the orthogonal curvilinear coordinate system. As an example, the derivation of the unit basic vectors self space coordinate in the spherical coordinate system and the cylindrical coordinates system is also discussed.
Key words: orthogonal curvilinear coordinate system, unitary matrix, unit basic vectors, derivative
