振动

• In wind instruments the sound is produced by a vibrating air column .
  管乐器的声音是由振动的气柱产生的。
• The diaphragm vibrates , thus setting the air around it in motion .
  膜片振动，这使得周围的空气也动荡起来。
• The atoms are displaced from their ideal locations by thermal agitation .
  原子会因为热振动从理想位置上位移。
• 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。
• 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。
• One of the features of a forced oscillation is the energy in the oscillation .
  受迫振动的特点之一是振动的能量。
• Such photons will excite the higher vibrational levels of the oh molecule .
  这种光子会激发OH分子的较高振动能级。
• 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。
• The weigh belt will turn on bin shaker to start the material moving again .
  带秤将开动料箱的振动器，以使物料继续流动。
• As the weights of the atoms increase, the frequencies of the vibrations diminish .
  当原子的重量增加时，振动的频率减少。
