衰减

• Such energy transformation is also known as energy degradation .
  这样的能量转化也被看作能量衰减。
• 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。
• The log decrement are suitable for determining interface bond damage .
  对数衰减率适宜于测定界面粘结的破坏。
• A specimen which is much thicker than the penetration depth decays exponentially .
  一个比穿深透度厚得多的样品，按指数律衰减。
• Attenuation of seismic waves between such surfaces can be similarly diagnostic .
  在这些界面之间地震波的衰减，同样可以作为一种标志。
• The ground will not have time to polarize completely and the decay will have a smaller amplitude .
  地层还来不及充分极化，衰减曲线的幅度将比较小。
• The pressure returns essentially to that in the incident blast wave which decays with time .
  压力大体上回复到随着时间逐渐衰减的入射爆震波的压力。
• It is easy to show, for an exponential decay, that the uncertainty in the life time is also z .
  很容易证明，对于指数衰减来说，寿命的不确定性也是z。
• For a target of any thinkness, the undeflected flux diminishes exponentially with thickness .
  对具有任意厚度的靶，无偏折的通量随厚度呈指数规律而衰减。
• However, it is not trivially easy to use this property for the attenuation of the detected surface-waves .
  然而，利用这种性质来衰减观测的面波并非十分容易。
