The Conrad Prebys Music Center's larger 400-seat concert hall follows the physical approach to acoustical design—in this case the inspired work of legendary acoustician Cyril Harris in collaboration with Ashton Taylor of HFP Acoustical Consultants in Houston.

康拉德。普利贝斯音乐中心的另一个较大的400座音乐厅采取了物理改变的方式进行声学设计-这样，印象深刻的杰作是由富有传奇色彩的声学家西里尔。

Chapter Two Further Study On Two Types of Tone Sandhis Supposed by Traditional Dialectology The further study is relied on the research of F0 and elapsed time, and more phonetic dealing with the original data.

对这一问题的分析将基于论文第一章所论述的上海方言单音节声调和两类变调的声学特性（基频F0和时长两因素），以及在这两个基本声学特性上所作的语音学意义上的对数据的进一步处理。

The results show the high accuracy quality of spectral element method and the stability of Newmark time integral method. Then some computational parameter is changed in example one such as the subdivision style of computational domain, time step length and such on. Some important conclusions and strategies for spectral element method with Newmark integral method for computational aeroacoustics can be given. The feasibility of spectral element method for computational aeroacoustics is verified.

计算结果表明谱元方法的高精度及Newmark时间积分方法的稳定性，并改变算例的计算参数，例如计算区域剖分方式、时间推进步长等进行了计算，得出了一些重要结论，为使用谱元方法结合Newmark积分求解气动声学问题积累了重要的经验，最终证明了谱元方法求解计算气动声学问题的可行性。

In order to test spectral element method and Newmark time integral, the codes of program and the feasibility of spectral element method for aeroacoustics, One question which has analytical solution and two typical questions of computational aerocaustics are simulated numerically by the program.

为了验证谱元方程和Newmark时间积分方法的正确性、自己所编程序代码的有效性以及谱元方法求解气动声学问题的可行性，本文使用程序分别求解了具有解析解的波动方程和计算气动声学问题中的两个典型问题。

The development of speech sounds was investigated using the analysis framework of phonemic contrast in Putonghua-speaking children.

普通话言语的发展：言语清晰度、音位对比及声学特征本研究采用音位对比的分析框架研究讲普通话儿童的言语声的发展，研究中采用了临床中的两种角度：知觉任务和声学性质。

Everyone has a very detailed subconscious knowledge of how different rooms sound, and although few are able to analyse the reverberation structure, most spot incongruities in artificial reverberation very easily.

通过不停的学习，你慢慢的基础过不同的真是声学空间，你的知识就越来越丰富，对于你创建一个模拟的声学空间就越容易。

The same position of each of the first plurality of acoustic drivers and the same position of each of the second plurality of acoustic drivers may be the center of the dust cap.

所述多个第一声学驱动器的每一个的相同位置和所述多个第二声学驱动器的每一个的相同位置可以是防尘罩的中心。

The low-frequency noise in the structure-acoustic field coupling system of high-speed train was simulated and analyzed.

对某高速列车拖车的仿真分析结果表明：该车声学测试点的总声压级超出了TB 1809—86标准拖车客室的容许噪声值；在某些计算频率下，车体某些部件涂敷阻尼材料后对客室测试点的声学贡献由小变大，这说明阻尼材料不仅改变了这些部件的振动幅值，同时也改变了振动相位。

First , a syllable-based Taiwanese speech recognition system was implemented. And the effect on the recognition performance of the syllable with entering tone was carefully exiamined. Based on the linguistics knowledge, the syllable with entering tone in database was re-labeled according to the tone sandhi of Taiwanese in order to improve the recognition rate. In addition, Kullback Leibler distance between the acoustic model before and after re-labeling was examined to verify the linguistics knowledge.

在论文中首先针对台语语音特性入声调的部份深入研究，我们由confusion matrix去分析入声调对辨识系统的影响性，且根据语言学上的知识修改文字拼音资料库，使得训练出来的声学模型更为可靠，进而提升辨识率；并利用Kullback Leibler distance去观察声学模型在修改前与修改后之间的差异。

Based on the violin, cello and double bass for the same position on the fingers rubbing strings rolling away from comparison and analysis of acoustic patterns; means single and double string rubbing rubbing means of acoustic string playing patterns and specific examples of analysis and comparison; refers to rub in the two-string Mixing strings with a single means to achieve the same sound, the string in the rubbing action on the comparison, so as to demonstrate the two-finger chord rubbing means smaller, the palm of your hand for a small, in the string rubbing speed, rubbing the string action is better than the single rate means the string rubbing , and can also increase the need for greater low-double bass string, the bit rate of rubbing

本文通过对小提琴、大提琴和低音提琴进行在同一把位上揉弦的手指滚动距离比较和声学图谱分析比较；进行单指揉弦和双指揉弦的声学图谱和具体演奏实例分析和比较；在双指揉弦与单指揉弦达到同样音响效果的情况下，在揉弦动作上的比较，以论证双指揉弦对于手指较细、手掌窄小的人来说，在揉弦速度、揉弦动作幅度上优越于单指揉弦，并且还可以根据需要更大程度上加大低音提琴低把位揉弦的幅度。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
