惯性

In Inertial frames and why the laws are the same in the train and on the platform, we introduced the idea of inertial frames - a frame of reference in which Newton's laws work.

在"惯性系：为什么火车上和月台上物理定律是一样的？"

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。

A method to acquire and track the beacon for deep space optical communication system is proposed, which uses star as beacon, and controls the direction of down beam based on the absolute position in inertial frame, the ephemeris of aircraft and earth and the attitude of aircraft.

提出一种深空光通信系统的信标捕获、跟踪方案，该方案是以恒星作为信标，根据恒星在惯性坐标系中的绝对位置信息，基于航天器和地球星历表、航天器的姿态信息来进行下行光束瞄准方向的精确控制。

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。

Adopting inertial coordinate frame simplifies modeling process and the dynamic inflow model can easily be incorporated without multi-blade coordinate transformation.

本文基於惯性坐标系的旋冀气弹建模方法简化了建模，方便地嵌入了动态入流模型。

Observed from an inertial reference frame, the net force on a particle is proportional to the time rate of change of its linear momentum: F = d / dt.

从惯性参照系看，作用在物体上的外力与冲量的时间变化率成比例。

No wonder that inertial mass is defined as its resistance to motion!

这样惯性质量被定义为运动的阻力就不足为奇了。

The precision of instruments that measure center of mass and inertial moments is below 1%. It is an advanced level of national and international.

本研究中还研制出了精度较高的人体惯性参数测量系统，其中，质心仪和转动惯量的测量精度均可达到1%以内，属国内和国际先进水平。

Inertial mass can be defined only in terms of certain mechanical measurements whose success hinges on Newton's law of motion.

只有用某些力学上测量，才能给惯性质量作出定义，而这些力学上的测量的成就是随牛顿运动定律而定的。

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。
