This paper presents the methods to improve the performance of mispronunciation detection at syllable level for Mandarin Chinese from two aspects: introducing the speaker adaptive training and the selective maximum likelihood linear regression to get a better acoustic statistical model, and proposing speaker normalization backend because of the limited information and the different rating level for the different pronunciation level.

该文一方面为了获得对于发音错误检测更好的声学模型，引入了说话人自适应训练和选择性最大似然线性回归技术；另一方面，由于字发音检错中存在严重的信息量不足问题和专家对于不同水平说话人的评价标注不一样，在后端上加入了话者得分归一化技术。

ECOTECT is a highly visual and interactive building design and analysis tool that links a comprehensive 3D modeller with a wide range of performance analysis functions covering solar, thermal, energy, lighting, acoustics, resource usage and cost aspects.

Then the developments of the thermoacoustic machine are reviewed. The thermoacoustic theory is introduced from different points of view. Two typical style of thermoacoustic engine are discussed, followed by thermodynamic circle, principal equations, fluid network principle and oscillation theory.

本文简要回顾了热声学的历史和研究现状，并从几个不同的角度对热声机械的基本原理进行了简要介绍，接着对二种典型形式的热声发动机装置进行了介绍，然后介绍了热声热机的热力循环、基本方程以及流体网络理论和振动理论。

In this system, a simple acoustic recognizer is constructed based on VQ, DHMM and One-Pass search algorithm. The baseline system will be the basis of research work in this dissertation.

在这个系统中，以VQ、DHMM和One-Pass搜索算法构成一个较为简单的声学识别器，这个基本识别系统是本文中进一步研究的实验平台和基础。

For the first time, we combined ultrasonic wave and time domain reflectometry to study the relationship between gas hydrate saturation and acoustic parameters in the process of gas hydrate formation and dissociation, and got fine results.

本文首次利用超声和时域反射联合探测技术，研究了沉积物中水合物饱和度与声学特性的关系，并对时间平均方程、伍德及其修正方程、李权重方程和BGTL（Biot-Gassmann Theory by Lee）理论等常用的水合物饱和度估算模型进行了验证。

This research has provided both data and method for acoustic remote measurement and inversion of physical and mechanical properties of seafloor sediments.

In order to test the feasibility of spectral element methods, time integral methods and absorbing boundary conditions for aeroacoustics, several programs based of Microsoft Visual C++ are presented for different time integral methods and boundary consitions.

为验证本文的谱元方法、时间积分方法和吸收边界条件对于求解气动声学问题的可行性，本文基于Microsoft Visual C++平台编制了分别采用不同时间积分方法和边界条件的谱元算法程序，计算结果证明了谱元方法的高精度以及两种时间积分方法的可行性。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
