And the points within the cartesian coordinate system are ,笛卡尔坐标系统中的点称为
Cartesian coordinate system 笛卡儿座标系统
In short , vector data take the simplest topological entities - points , lines , and polygons - and anchor them within a 2 - d cartesian coordinate system to describe geographical features 简言之,矢量数据利用最简单的拓扑实体点、线和多边形,并在二维笛卡尔坐标系统中固定它们来描述地理特征。
Simply supported and multilayered magneto - electro - elastic plates : the state vector equation of transversely isotropic magneto - electro - elastic solid is established from its governing equations in a cartesian coordinate system 对于简支压电压磁弹性层合板问题,从它的基本方程出发,建立了压电压磁弹性层合板的状态变量方程。
Because geometry of formation of two satellites is very weak , the solution covariance is very big and unstable in order to resolve this problem , the measurement model was transformed from cartesian coordinate system to sphere coordinate system 由于双星编队星座观测的几何结构弱,所以解算参数的协方差不稳定。为了解决这一问题,对测量方程进行球坐标变换。
A Cartesian coordinate system specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances from the point to two fixed perpendicular directed lines, measured in the same unit of length. Each reference line is called a coordinate axis or just axis of the system, and the point where they meet is its origin, usually at ordered pair (0,0).
