查询词典 frame of reference

We know that light in inertial reference frame, Naturally satisfy the sum theorem of classical mechanics in speed (since so far we have not found exception to overthrow it is inertial basis).

我们知道，光处在惯性系中，自然也就满足经典力学中速度相加定理（因为至今我们还没有找到推翻它是惯性系中特例的依据）。

Principle of d′Alembert Lagrange for a system relative to a non inertial reference frame and non isochronal variation is first presented.

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。

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。

In 1987, Kane et al.〓investigated the dynamics of a cantilever beam in a non-inertial reference frame.

建模时如果不考虑这种因素的影响，将会导致错误的结论。1987年，Kane〓对非惯性系下的旋转弹性梁的动力学特性进行研究，指出在转速较大的情况下，按零次近似建模理论进行仿真计算会得到梁的挠度趋于发散失稳这样一个错误的结论。
