查询词典 sound boarding

On the basis of investigating the sound field of a plane piston transducer and the relations between sound field and radiation force, by settling four plane piston transducers driven at the same frequency at each corner of a regular triangular pyramid with their sound-beam axes crossing at the center of the pyramid, this technique uses ultrasonic wave synthetic theory to acquire a three-dimensional ultrasonic standing wave field. The micro-component can be captured, transported, released in the range of space by adjusting the phase of the transducers.

在研究单个圆形平面活塞换能器声场分布以及声场和辐射力关系的基础上，将以相同频率驱动的4个平面活塞换能器呈正四面体放置，利用声波合成原理获得三维超声驻波场，通过调整各个换能器发射信号相位之间的关系实现对微构件在空间范围内的俘获、移动、释放等操纵。

There are supplemental components, in particular Cue-Cutter, intended to spilt files, transformer WAV and MP3 in sound effects, the built-in sound reproducer, and also the module of sound recording.

有补充成分，特别是线索刀具，打算泼档案，变压器WAV和MP3播放，在声音效果，内置在健全reproducer ，也是模块的录音。

Experiments are carried out to give the transfer functions of each part in the ANC system, the spatial coherences of sound field and the Nyquist plots of the whole system. The results show that reverberant sound will also produce some unstable poles because of different time delays are needed in establishing normal mode response, but the gain margin is much greater than that for direct sound.

文章还从实验的角度，对ANC系统各个部分的传递函数、声场的空间相干性与系统的Nyquist图进行了分析，结果说明，混响声场的建立也需要一定的时间，所以混响声传播途径也将给系统带来一些不稳定的极点，但是它的增益裕量要比直达声途径大很多。

" The ringdove said:" If you can change the sound of your cry, it will be all right; if you cannot change the sound of your cry, even if you move to the east, the villagers will still detest your sound.

"斑鸠说："要是您能改变叫的声音，那就行了；要是您不能改变叫的声音，那么就是您搬到东边去，那儿的人还是会讨厌您的叫声。

Several stars plunder the bird with the whole family to live in together, some of them imitate the sound which the child makes a tearful scene, a some imitation pair of lover long string kiss sound, some imitations open the door the sound, but also some imitation teapot burns time the boiling water scat singing ......

几只星掠鸟跟一家人生活在一起，它们有的模仿小孩子哭闹的声音，有的模仿一对恋人一长串的亲吻声，有的模仿开门的吱呀声，还有的模仿茶壶烧开水时的哨声

A semivowel, one having an audible sound by the addition of another Letter; e.g. S and R. A mute, one having no sound at all by itself, but becoming audible by an addition, that of one of the Letters which have a sound of some sort of their own; e.g. D and G.

元音是不需要别的字母辅助即可发音的字母；半元音是由另一个字母辅助才能够发出声音的字母，比如S或R；哑音字母自身不能发声，必须有另外一个自己能发声的字母辅助才能发声，比如D或G。

One must have a mind of winter To regard the frost and the boughs Of the pine-trees crusted with snow; And have been cold a long time To behold the junipers shagged with ice, The spruces rough in the distant glitter Of the January sun; and not to think Of any misery in the sound of the wind, In the sound of a few leaves, Which is the sound of the land Full of the same wind That is blowing in the same bare place For the listener, who listens in the snow, And, nothing himself, beholds Nothing that is not there and the nothing that is.

若想敬仰松树枝干层层为霜雪覆盖，你得具备冬天的头脑。在寒冷中持久凝视，那冰雪蓬松的刺柏丛林，那闪烁在远处腊月阳光下的迷漫云杉。不要去想那风声和树叶夹带着的凄凉。这声音是风地里的声音，这风是为在空地上的你而吹。在雪里聆听的人儿啊，听着与己无关的事儿，那儿不存在的东西看见，眼里只有现存的一片空旷。

If you make them sound minor –"I cant come in as Im a bit low"– you sound like a shirker. If you make them sound major, you seem like a nutter.

如果你的表达让它们听起来不算大问题——"我不能去上班了，因为我情绪有点低落"——那么听起来你就象一个开小差的人。
