参考系

The concepts of leading-force and leading-work in laboratory-reference-system are established and the process of inelastic collision between two bodies is examed.

在实验室参考系建立三维引导力与引导功的概念，研究了两物体非弹性碰撞过程。

Therefore, I offer my proposal that there exists the indeterminacy of reference system in 'the changes of location' of the same event in the inertial frame.

为此，我提出惯性系的同一事件"位置的改变"存在参考系的不确定性。

In order to provide references for the ground separation tests and the separation system design, characteristics of the constrained and centroid biased on-orbit satellite separation were analyzed in inertial reference frame.

为了给分离地面试验和分离系统设计提供依据，在惯性参考系中分析了筒式偏心在轨分离问题的运动特性。

Foucault's pendulum, and other much more sensitive experiments, demonstrate that an inertial frame is also one in which the distant galaxies do not appear to rotate.

一节，我们介绍了惯性系的概念：找一个参考系使牛顿定律适用于傅科摆和其他更敏感的实验，而我们发现在这个惯性系中遥远星系是不转动的。

As a result, there would be no irresistible confusion brought about by the physicists' inability to distinguish whether the reference system for 'the changes of location' of the same event in the inertial frame is absolute or relative.

这样，可以避免物理学家无法区别惯性系的同一事件"位置的改变"参考系是绝对还是相对所带来的难以抵抗的模糊。

In this article, I start from the foundation of classical physics-uniform linear motion, then extend to the foundation of modern physics, illustrating through solid evidence, the notion that 'the change of state' and 'the change of location' of inertial frame are two different concepts as well as my idea that in inertia system the reference system for 'the change of location' will not necessarily exist independently from natural object.

本文中我大体上从经典物理学基础的匀速直线运动开始并延伸到近代物理学的基础，以实证的方法阐述惯性系"状态的改变"与"位置的改变"是两个不同的概念，以及我对惯性系"位置的改变"参考系未必能脱离自然客体而独立存在的看法。

To explain why the frame of the distant galaxies is an inertial frame, we really need either Mach's principle or another postulate.

为了解释遥远星系参考系是惯性系，我们要么需要马赫原理，要么需要其他什么假定。

The moving reference frame is used in the impeller region and the boundary conditions are velocity inlet and pressure outlet.

在计算时对于叶轮区域采用旋转参考系的方式，边界条件分别是进口速度边界条件以及出口压力边界条件。

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。

Simultaneity depends on the system from which you observe it, right?

同时性取决于你从那个参考系来观察，不是吗？

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。
