坐标系统

There were many champions of synthetic geometry , Euclid-style development of projective geometry, in the nineteenth century, Jakob Steiner being a particularly brilliant figure.

该模型的欧几里得的要素，发展的几何连接作为一个不言自明的制度，是在紧张与笛卡尔的减少几何代数通过坐标系统。

A tolerance analysis procedure based on homogeneous transform and Monte Carlo Simulation is proposed in this research. The propagation of variation in 3-D space is treated as propagation of errors during transformations of Cartesian frames, which are set up on the Key Characteristic Points.

通过定义车身装配坐标系统，根据微分运动的原理，建立了计算车身零部件位姿关系的数学模型，对典型公差语义的数学表达进行了研究；并应用蒙特卡洛模拟，对关键特征点偏差传播的统计特性进行了分析。

In the western mining areas, when from adjustment to restriction adjustment, the original national control points are of low grade, or the points are destroyed and the surface movement is out of shape. thus, there are few control points and the reference frame conversion is a big problem in the western high elevation areas. As a result, this thesis makes a reparable design in accordance with the key problems of holing through survey.

本文就利用GPS技术测设地面近井点的网形布设、观测方法、数据处理作了相应阐述；并对由无约束平差到约束平差时，西部地区可能遇到在矿区分布的原有国家控制点往往只有低等级点，或点位遭破坏、地表移动变形等可能使可用控制点很少的情况、以及西部高海拔地区坐标系统变换问题，提出了针对贯通测量的关键问题应对方案。

In order to locate the human structure in 3-dimensional space precisely and to compare the data set among different individuals conveniently, we suggested and created a universal coordinate system of the human body in which the pubic symphysis horizontal plane was determined as the universal standard original zero plane.

为了确定人体结构在三维空间中的准确定位以及在不同个体之间便于比较，文中提出和建立了可视化人体的整体坐标系统。

Then, in support of his covariance principle, Einstein [2] remarked, It should be noted that this result, also, of the theory is not influenced by our arbitrary choice of a system of coordinates.

于是作为支持他的协度变原理，爱氏评论道：请注意这结果，而且这理论是不受任意选择坐标系统所影响的。

This coordinate department is approximate 1954 Beijing coordinate system, central meridian is 111 degrees 00 minutes, umbriferous face 110 meters, tierce of the 37 .

该坐标系为近似1954年北京坐标系统，中心子午线为111度00分，投影面110米，带号37。

This is because projected coordinate systems have a Y-axis which is the opposite of pixel coordinate systems.

这是因为预计坐标系统有一个Y轴是相反的像素坐标系。

The center of the global coordinate system is labeled "'''W'''"; the Z axis is not visible.

整个全局坐标系统的中心被标注为"'''W'''"；Z 轴是不可见的。

Based on the hybrid coordinate ocean model, the climatically global ocean current system is established.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
