振

• Suitable noise and vibration isolation, and protection against freezing must be provided .
  必须提供适当的消声和隔振以及防冻措施。
• Thomas hudson drank the glass at a gulp and it was warming and inspiring .
  托马斯赫德森举起杯子，一饮而尽，只感到一阵暖意，精神一振。
• The dynamics of the feed system are also an integral part of feed system coupled modes .
  供应系统动力特性也是供应系统耦合振型的主要部分。
• The higher modes have shorter periods than the fundamental mode and, moreover, they have higher velocities .
  高振型波比基阶振型波周期短，波速高。
• Even a nominally linear device can be linear only up to a certain limiting amplitude .
  即使名义上为线性的装置，仅在某个有限的振辐之内才可能为线性。
• The rotating weight exciter even has been used in its simplest form as a single arm device .
  旋转重物激振器甚至曾经以单臂装置这样最简单的形式使用过。
• This requirement is not essential in practice if the locations of the exciter stations are chosen judiciously .
  如果激振点安设得当，这个要求在实际上并不重要。
• The combustor resonance properties are portrayed by instability zones, one zone for each acoustic mode .
  燃烧室的共振特性用不稳定区表示，每种声振型都有一个这样的区域。
• There is, however, an additional contribution arising from those oscillators in the vicinity of the aperture's edge .
  然而还存在着由孔边界附近的那些振子所产生的另一项贡献。
• Galloping oscillations are usually violent and must be damped structurally, which is a near impossibility .
  疾振通常是强烈的，必须从结构上进行阻尼，但实际上几乎不可能做到。
