Curvilinear orthogonal coordinates 正交曲线坐标
With the development of production and technology , non - orthogonal coordinate system is demanded in more and more fields 随着生产和科学的发展,出现了越来越多的场合要求采用非正交系坐标测量系统。
The study of this project will work as reference to research and development of the non - contact measuring system based on the un - orthogonal coordinate later 本课题的研究将为非正交坐标系下的非接触测量系统研制与开发起到一定的借鉴作用。
