坐标系的

Two different methods based on ship rectangular frame and inertial frame are proposed separately according to consistence of radar base angle and beam angle.

本文首先研究了舰载两轴雷达系统抑制船摇的方案，对雷达天线转角和波束转角一致和不一致的情况，分别提出了基于甲板坐标系稳定和基于大地坐标系稳定的不同方法。

Coordinate system is the foundation of spatial data and geographical information system.

1引言坐标系是空间数据的基准，也是地理信息系统的基础，正确定义GIS系统的坐标系至关重要。

It is difficult to directly employ the GPS owing to the inaccessibility of the ellipsoidal parameters and projection parameters of the independent coordinate systems.

但是在有些地区使用的是某些独立坐标系，并且独立坐标系和 BJS- 5 4系之间的转换关系一般是保密的。

The equivalent form for the PI regulator in stationary form is deduced and a resonant link is proposed.

最后分析了旋转坐标系下能实现稳态无静养的比例积分器在静止坐标系下的等效形式，提出包含单次谐波内模的谐振控制器。

In a polar coordinate system, the concept of image area extension is established, and the uniqueness problem is discussed for an image whose Fourier series expansion of grey only contains the 0th-order and 1th-order terms.

同时本文以极坐标系表示图像平面，建立了图像区域延拓的概念，讨论了由灰度关于极坐标系角度坐标的富里叶展开式仅含零阶和一阶项之图像恢复物体外形的唯一性问题。

Pointing out that the singularity revealed the defects of the general relativity in theory and was not the intrinsic property in the nature world.

而通常所说的光速不变原理，指的是在惯性坐标系或局域惯性坐标系中，真空中的光速各向同性

The second part, we select the coordinate system for the sun to study the Earth's revolution, when the introduction of the Coriolis force on the impact of the spacecraft, and further selected for the reference system on Earth, the establishment of coordinate system, taking the Earth's non-inertial reference frame, the Coriolis profit impact of forces on the spacecraft.

第二部分，我们选取太阳为坐标系，研究地球公转时引入的科里奥利力对飞船的影响，并且进一步选取地球为参考系，建立坐标系，考虑地球为非惯性系时，科里奥利力对飞船的影响。

We have described two events happening at the same time in one c.s., but at different times in another c.s.

我们已经描述过，在一个坐标系中同时的两个事件，在另一个坐标系中却不是同时的。

This would mean that there exists one c.s. distinct from all others, at rest relative to the ether-sea.

这意味着有这么一个跟所有别的坐标系都不同的坐标系，它对于以太海是静止的。

A Prove that d/dx is a linear operator on V. b You can put a coordinate system on V by mapping p to p(0, p(1), p(2).(Please imagine that flipped 90 degrees so it is a column.) Find the matrix that represents d/dx in this coordinate system.

1证明d/dx是V上的线性算子；2你可以将p映射到p(0， p(1)， p(2)，从而给V加上坐标系（想象将其翻转90°，形成柱体），找出在此坐标系中代表d/dx的矩阵。

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。
