噪

In the last few years, researches the problem of the underwater sail machine's sound have been common, the content of the research is very extensive, including the modeling, method of its solution, frequency curve, the wave's property in spreading, the syntonic frequency and the damp material on such coupling system.

近几年，水下航行器的声振一直是国际上研究的热点，研究的内容非常广泛，其中涉及这类耦合系统的建模、求解方法、频散曲线与传播波性质、外激励下的共振频谱及阻尼材料降噪等。

Aiming at the characteristics of underwater acoustic transient signals emitted from antisubmarine weapons dropping into watertorpedo, aerial sonobuoy and rocket assisted depth charge etc.

针对鱼雷、空投浮标、火箭助飞深弹等反潜武器入水瞬间产生的水声瞬态信号所具有的持续时间短、信噪比低、突发和不稳定等特点，以传统的Page-T est检测器为基础，提出了一种新的水声瞬态信号检测方法。

We had no idea you had such a beautiful soprano voice!

我们不知道你竟有一副这么美妙的女高音噪子！

The results showed that the insertion loss measured in the sound field is lower than the simulating results.

对声屏障实测降噪效果与仿真模拟结果进行了比较，实测结果与模拟结果具有相同的变化规律。

Function and Advantages: It features such function as superb sound absorption; shock proofing, water proofing, impact resistance and beautiful texture appearances.

功能与优点：具有极强的防锈蚀、防渗水、隔音降噪、堵漏修补、防撞击等功能，可以提供持久的保护作用，全面延长车底盘使用寿命。

A low cost portable upper atmospheric sounding system used by both balloon and m icrorocket is presented, which has much lower ratio of signal to noise and wid er bandwidth.

本文介绍通过提高接收系统的信噪比同时采用宽波束接收天线，研制了一套低成本、轻便式高空大气探测简便系统。

As with many low-cost vehicles, a large amount of soundproofing was omitted, meaning that road vibrations, engine sound and wind noise are noticeable for the passengers.

正如许多低成本的车辆，有隔音大量资金被省略，这意味着这条道路的震动，发动机声音和风噪是为乘客明显。

During the design stage, Baltic Yachts paid particular attention to reducing vibration and noise, both from external sources as well as from the engine room, drawing on the expertise in this sector of Dutch designers who have developed solutions able to enhance acoustic comfort in interior design through improved soundproofing insulation.

设计阶段，Baltic Yachts为减少外部和引擎室噪音和震动大费心血，采用荷兰设计师研发的减噪方案和隔音层，提高了内部的声音舒适度。

Based on wavelet transform image denoising the Matlab program's source code, easy to use!

基于小波变换的图像去噪的matlab程序的源代码，很好用！

The statistical discrepancy of each spectral data point is estimated, then the contiguous data points are integrated adaptively based on the statistical discrepancy. Comparing to the fixed width binning, the proposed method can overcome the following negative effects on the subsequently statistical analysis. For example, signals with opposite statistical discrepancies may be superposition in a same region.

通过计算各数据点统计特性，并根据相邻数据点的统计差特性进行自适应积分，克服了目前普遍采用的等间隔分段积分法可能存在的缺陷(如统计差异性相反的信号相互抵消、微弱特征信号被掩盖及谱图信噪比下降等)，从而避免了对后续统计分析所产生的负面影响。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
