Geographical coordinate system is another story, there are a number of different systems, and some of them are very exotic.

地理坐标系统则是另一回事，有不同的系统的数目，其中一些非常奇特。

You saw ways to convert between the 2D coordinate system of the screen and the 3D system of the world.

你看到的方法之间转换的二维屏幕坐标系统和世界的3D系统。

Remember that the z-coordinate is negative because OpenGVS uses the same right handed coordinate system to remain compatible with OpenGL (remember,+Z is out of the screen toward the eyepoint, so we are conceptually moving our sample object "into the screen" away from the eyepoint so we can see it).

记住Z坐标是相反的，因为OpenGVS用一样的右手坐标系统去保留对OpenGL的兼容（记住，+Z从银幕而出指向眼睛的，所以我们观念性的移动我们的例子，使之背离眼睛进入荧幕，所以我们能看见它）。

The coordinate system conversion and the map projection are the key technique in GPS navigation system.

坐标系统转换和地图投影是GPS导航系统中的核心技术。

As an important part of GIS platform, spatial reference system includes coordinate transformation and map projection, also named as Map projection transformation system.

GIS中的空间参照系统是GIS平台中的重要组成部分，内容包括各种坐标系统的转换和地图投影，故也称为投影变换系统。

Firstly this paper introduces some basic information about the determination of satellite orbit, including time systems, coordinate systems, the definition of these systems and the transfer between different systems.

METHODS Within a three-year period,510 cases of X-knife treatment were taken,using the standard axial serial CT scan for stereotactic localization.The target was localized by the BRW coordinate system,Radionics RSA-3 X-knife treatment planning system was adopted to make plan,and Philips SL-75-14 Linac was used to produce X-ray.

A new analytic scheme for solving the inverse kinematics equations of CRS robot manipulator was presented by the shift of the joint coordinates and the rotation coordinate system, which were significant to optimize the robot motion and path planning, and the formulas of calculating the sine and cosine of each rotate angle variable were solved.

通过关节坐标的转换和旋转坐标系统的引入，给出了CRS机械手逆运动方程求解的一种新解析法，直接推导出各个关节转角变量的反三角公式，为机械手的运动优化和轨迹规划创造了条件。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
