，笛卡爾坐標系統(tǒng)中的點稱為 - Cartesian coordinate system
笛卡兒座標系統(tǒng) - 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
簡言之，矢量數(shù)據(jù)利用最簡單的拓撲實體點、線和多邊形，并在二維笛卡爾坐標系統(tǒng)中固定它們來描述地理特征。 - 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
對于簡支壓電壓磁彈性層合板問題，從它的基本方程出發(fā)，建立了壓電壓磁彈性層合板的狀態(tài)變量方程。 - 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
由于雙星編隊星座觀測的幾何結(jié)構(gòu)弱，所以解算參數(shù)的協(xié)方差不穩(wěn)定。為了解決這一問題，對測量方程進行球坐標變換。 - It's difficult to find cartesian coordinate system in a sentence. 用cartesian coordinate system造句挺難的
