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。

However, when we play the harmonica, the sound we hear is not the actual vibration of the reed itself, but instead the sound of a column of air being set into motion by that reed.

但是，在我们吹奏口琴的时候，所听到的口琴声却不是由簧片本身的振动产生的。

In order to decrease the vertical vibration of rolling stock, the air springs with variable damping oil dampers inside are developed.

为降低铁道车辆的垂向振动，开发了内置可变阻尼油压减振器空气弹簧。

Because the change of the pressure caused the change of the mucosity coefficient of the air, the resonance frequency, the air damping and the bias were changed.

由于气压的变化会引起空气黏性系数的变化，因而会引起MEMS梳状线振动陀螺仪谐振频率、阻尼系数、零偏等参数的变化。

The cover plate constructed in this way reduces disk vibration due to air damping effects resulting from a narrow gap between the disk and the cover plate while suppressing noise due to the presence of the abruptly expanded portion.

以这种方式构成的盖板由于盘片和盖板间的间隙产生的空气减振效果，减少了盘片的振动，同时由于设置有突扩部分，降低了噪声。

This engine drew engine of OHV strong, torque mixes motivation greatly OHC the advantage such as province oil, Jing Yin, low vibration, in technical respect far on these two kinds of type, especially forefathers the crankshaft shift technology of one pace (watertight aircase of way of Off Set Crank), double energy of life (rocker of valve of Two Ways Air Jacket), roller (the 6 old techniques such as Roller Locker Arm) have epoch-making sense more.

该发动机吸收了OHV动力强、扭矩大和OHC省油、静音、低振动等优点，在技术方面又远在这两种机型之上，非凡是先人一步的曲轴移位技术、双气道空气箱、滚子气门摇臂等六大技术更具有划时代的意义。

The vibration produces sound waves in the air, which travel to our ears .

振动在空气中产生了声波，它传到了我们的耳朵里。

The oscillation of an air-filled double-layered spherical shell immersed in water was examined.

研究了浸没於水中的双层球壳振动问题。

The innovative use of these materials further absorbs vibration and leads to longer and more reliable airframe and electronics life.

创造性地利用这些材料，进一步吸收振动并导致更长和更可靠的机身和电子生命。

Use this patent product to detect the airscrew precision that repair crosses rises, the vibration in locomotive process and noise are reduced greatly, propulsive efficiency has rise apparently.

利用该专利产品检测修复过的螺旋桨精度提高，在运转过程中的振动和噪声大大降低，推进效率有明显提高。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
