The energy of an atom or molecule is described in terms of translational rotational vibration and electronic energy . 原子或分子的能量,按平动转动振动和电子能来描述。
The mix is placed in the form on the machine and is removed after a minute or less of vibration . 这种拌合物注入机器上的模型器内,经一分钟或更少时间的振动后即脱模取出。
The absorption peaks arising from unsaturated and aromatic vibrations are considered in chapter 3 and 5 . 由不饱和以及芳香化合物振动产生的吸收谱带将在第三和第五章中讨论。
Subsidiary costs for insurance premiums, inspections and ground vibration control can add up considerable amounts . 保险费,检查和地层振动控制的辅助费用可增加相当可观的数额。
The vibration is varied in frequency over a range on the order of 5 to 2, 000 cps, usually at a constant octave . 振动的频率在5到2000赫的范围内变化,通常用一常值的八阶变化率。
The spectrum curves determined for linearly elastic systems still have significance for nonlinear hysteretic vibrations . 线性弹性系统确定的谱曲线对非线性滞回振动仍然是有意义的。
In solids, the particles are held so firmly that their motion is restricted to vibration about fixed positions . 固体中的粒子结合得如此牢固,以致它们的运动只限于固定位置里作振动。
A series of seismographs are arranged with their direction of vibration along the generators of a cone with vertical axis . 一组地震仪的振动方向是与具有垂直轴的锥体拾震器方向一致的。
The simplest form of wave motion consists of the combination of a transverse simple harmonic vibration and a uniform translation . 波动的最简单形式是横向简谐振动和匀速直线运动的组合。
Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. The oscillations may be periodic such as the motion of a pendulum or random such as the movement of a tire on a gravel road.
