| 1. | The nitrate ion has four fundamental modes of vibration . 硝酸离子有四个基频形式。 |
| 2. | The frequency and amplitude of vibration are monitored . 振动的频率与振幅受到监控。 |
| 3. | It should be noted that the vibration is not wig-wag . 要注意,这里讲的振动不是摇摆。 |
| 4. | The vibrations accompanying the rebound are the earth quake . 伴随这种回弹的振动就是地震。 |
| 5. | The blade is clamped and excited into some mode of vibration . 叶片夹好后,被激发进入某种振动状态。 |
| 6. | The vibration will decay or damp as a result of the dissipation of energy . 振动因能量耗尽而衰减或阻滞。 |
| 7. | The eccentric mass type vibration generators are bolted to the platform . 偏心量型式的振动发生器锚固在台身上。 |
| 8. | The level of mechanical vibration during operation must be determined . 机械在工作期间振动的量级必须予以确定。 |
| 9. | Certain modes of vibration may be suppressed while others may be enhanced . 某些振型可能减弱,而另一些则可能加强。 |
| 10. | Damping wakes possible finite steady-state vibration amplitude at resonance . 在共振时,阻尼可能限制稳定振动的振幅。 |
