Suppose you want a coordinate system that has its origin 200 pixels from the left edge of the client area and 150 pixels from the top of the client area 假定您需要原点距工作区左边缘200像素、距工作区顶部150像素的坐标系统。
The common point of motion control system lies in its position control to working axes . the axes could be positioned according to another axes or coordinate system 此轴可以相对于某一主轴（主轴定位）或相对于某个坐标系统（坐标系统定位）进行定位控制。
Article 9 relatively independent plane coordinate systems may be established in local areas on account of the needs of construction , urban planning and scientific research 第九条因建设、城市规划和科学研究的需要，局部地区可以建立相对独立的平面坐标系统。
The following code placed at the end of the preceding example creates a path that consists of a single rectangle with its lower - left corner at the origin of the new coordinate system 下面的代码（置于前面示例的结尾处）创建了由一个单独矩形组成的路径，该矩形的左下角在新坐标系统的原点。
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。
Key realization technology of this system that included the space coordinates built , node model base established , scene structure expressed by data and safety rules checking was studied 研究了系统实现的关键技术，这包括空间位置坐标系统的确立，节点改模型库的建立，虚拟场景的数据构建及安全规程的校验方法。
For example , you can use the world transformation to revise the coordinate system and use local transformations to rotate and scale objects drawn on the new coordinate system 世界变换可与局部变换合并，以得到多种结果。例如，世界变换可用于修正坐标系统，而局部变换可用于旋转和缩放在新坐标系统上绘制的对象。
For example , suppose you want to use inches as the unit of measure and you want the origin of your coordinate system to be 2 inches from the left edge of the client area and 1 2 inch from the top of the client area 例如，假定您想使用英寸作为度量单位，并且想让坐标系统的原点距工作区左边缘2英寸、距工作区顶部1 / 2英寸。下面的示例设置
Our routing protocol imposes a flexible and intuitive coordinate system onto the deployment area and partitions the anonymous nodes into clusters where data can be gathered from the environment to collect data 协议针对传感器网络节点所覆盖的区域建立起一个灵活的、直观的坐标系统,利用坐标系统把位置不明的传感器节点分成一个个能从环境中采集数据的簇群,进行数据采集。
Under the cylindrical coordinate , the transit - time effect of the radial gap in the resonance cavity of rtto is studied by hydrodynamic theory . the equation describing the interaction between the electron beam and the high frequency field is obtained 在柱坐标系统中，我们用流体理论方法分析了rtto谐振腔间隙的渡越时间效应，得到了在有限渡越角情况下电子束与高频场相互作用的方程。
