The Red Sea has used the diameter is the 9cm static figure radiation ventilator, but pursues the static sound to play the family to be possible to purchase a ventilator velometer, the hand control ventilator's rotational speed adjusts between 1200-2200 rpm, ventilator's noise is also is situated between 15-25db10% differently according to the rotational speed, both has satisfied the radiation request, and may according to user's need, the adjustment wind speed realize the user static sound demand.

红海采用了直径为9cm的静音型散热风扇，不过追求静音的玩家可以购买一个风扇调速器，手动控制风扇的转速在1200-2200 rpm之间调整，风扇的噪音也是根据转速的不同介于15-25db±10%，既满足了散热要求，又可以根据用户的需要，调整风速来实现用户静音的需求。

In order to explore the principle of sound of the cricket's different sounds,we regarded adult Gryllus bimachlatus as experiment materials,recorded and analyzed with the sounds acquisition software Cool-edit 2000,took photographs in random to record changes of position of cricket's wings,measure and analyze angles between the wing and the body when the cricket send out different sounds,and reseach the vocalism's structure of the cricket's different sound.

为探索蟋蟀不同鸣叫声的发声原理，以双斑蟋成虫为实验材料，用Cool-edit2000声音采集软件记录、分析，同时用数码照像机抓拍蟋蟀各种鸣叫瞬间的翅膀位置，分析测量不同鸣叫声时翅膀与身体所成的角度，对蟋蟀的三种不同鸣叫声的发声结构进行了研究。

The children demonstrated faster development of vocalization behaviour and spontaneous alerting to sound than deriving meaning from sound.

Whereas the history of the silent film could be summarized as the discovery of the different means of roducing an evocative succession of visual images, the history of the sound film is the discovery of the different means of producing an vocative integration of visual images and sound.

如果说，无声电影的历史可以概括为产生了一环套一环的视觉形象，那么有声电影的历史是产生一环套一环的视觉形象与声音的结合的种种不同的方式。

We can put in another way, let's take musical instruments for instance, maybe there are a few kinds of musical instruments can generate 1KHz sound, but we can easily distinguish which sound comes from which musical instrument, this is because every musical instrument, even every person has its own unique voiceprint.

以乐器来当例子，也许有几种乐器，它们同时都能发出1KHz的声音，可是人耳就是能轻易的分别那个声音是来自於那个乐器，这就是因为每种乐器，甚至是每个人都有独特的声纹。

Vortical flow can be produced by the sound wave incident on a small orifice in some circumstances, which results in significant sound absorption.

在一定条件下声波入射在小孔上会激发出涡流，并引起入射声能的高效吸收。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
