  2. 3. the effect of measurement error is considered as gauss white noise. through theoretical analysis and numerical simulation, damage assessment results are also subject to gauss distribution. furthermore, results indicate that the mean keeps intact, but the standard deviation is linear to error level

    3 、將測量誤差的影響考慮為正態分佈的高斯白噪聲，通過理論分析和數值模擬，說明用靈敏度分析法識別結構損傷時，損傷識別結果也服從高斯正態分佈，其平均值保持不變，而方差則與誤差水平成線性關系。
  3. This article firstly deal with the sound source, noise measurement and analysis, noise control principle and some basic noise control technology, then elaborate the current noise detection standard and method for the coach in our country, the noise mechanism. characteristics and the measures of noise - controlling, finally. describe the actions of noise control, noise detection and optimization in our coach detailedly, which have met with the expectation

    本文首先敘述了聲音的產生原因、噪聲的度量和分析方法；介紹了噪聲的控制原理和原則以及一些基本的噪聲控制方法。然後，介紹了我國目前的客車車內噪聲的檢測標準和方法；詳細闡述了客車主要噪聲源的產生機理和噪聲特性以及車內噪聲控制措施；最後，理論與實際相結合，對我公司的lck6122型大型客車採取了相應的噪聲控制措施以及並其進行了測試和優化。
  4. The measurement precision mainly depends on two aspect, one is the phase noise of frequency standard, the other is the linearity of phase detector in the range from 0 to 360

    此方法測量精度的高低，主要取決于兩個方面，即頻率標準本身相位噪聲的情況和在0 360范圍內鑒相的線性度。
  5. Acoustics - measurement of sound insulation in buildings and of building elements - laboratory measurements of the reduction of transmitted impact noise by floor coverings on a heavyweight standard floor

    聲學.建築物和建築構件的隔聲測量.第8部分:重型標準地板鋪設面層使傳遞的撞擊噪音減低的實驗室測量
  6. Acoustics. measurement of sound insulation in buildings and of building elements. part 8 : laboratory measurements of the reduction of transmitted impact noise by floor coverings on a heavyweight standard floor
