声学

The principle and the development status of temperature field measurement by acoustic tomography are introduced in this thesis.

本文介绍了声学温度场检测技术的基本理论、发展现状。

The pressure fluctuations were measured at different positions along the axial direction on the tonge. The coherence analysis was utilized for illustrating the blade passing frequency cancellation mechanism. A 3-D flow visualization method, which overcame the blind slight from LDV and PTV, was used to present the differences of internal flow patterns.

实验中分别进行0度、5度与10度三种叶轮扭转角之设计，在横流扇出风口以声学人偶进行噪音量测，评估不同叶轮扭转角在操作转速下之风扇噪音、并分析其声音品质；另外在舌端上不同的轴向位置撷取其压力扰动频谱进行相干性分析，探讨舌端上因不同叶轮扭转角对周期性压力扰动之破坏之探讨。

To solve the compensation problem for nonlinear transformation of acoustic model parameter in noisy environment,Parallel Model Compensation and Vector Taylor Series compensation are two mainly used model parameter compensation methods which can only reach accuracy of first order linear approximation.

首先，本文介绍了我们所提出一种新的语音声学模型在噪声环境下的参数补偿算法—UT变换补偿算法。

The statistical theory and Hilbert-Huang transformation were used to analyze the flame acoustic signals in time and frequency domains.

应用统计理论和Hilbert-Huang变换对炉内火焰声学信号分别进行了时域和频域的分析。

In this paper, not only the musical acoustics, twelve-tone equal temperament but also the overtone, the intervals are present. Some effects on the temperament and intonation are analyzed.

详细地介绍了现代钢琴的律制、音乐声学、十二平均律、谐音以及音程中所产生的拍音原理，分析了影响钢琴音律和音准的各种现实因素。

We determined the basic mechanical and acoustic behaviors of reconstructed cartilage plate compared to the tympanic membrane.

相较於耳膜，我们找出了用於重建的软骨板基本的动力学及声学的行篇模式。

From an acoustics point of view, the 0.2 to 0.5 mm cartilage plate depending on different areas of perforation seems to be most preferable with regard to tympanic membrane vibration.

由声学的观点而言，0.2至0.5公厘的软骨板於不同面积大小的破洞重建中，提供了较佳的耳膜振动。

The ubiquity of this phenomenon suggests that some biological functions are the same for all species—in fact.

这种现象的普遍性，告诉我们有关生物学的作用是经由这些特别的声学讯号而传递的。

Ultrasonics, a rapidly developing branch of acoustics, has many applications.

超声是近代声学中发展较快而应用较广的一个分支。

In the sense of Baudelairean synaesthesia, the retinal reception is expanded through the acoustic underpainting of a piano composition.

在Baudelairean通感意识，扩大视网膜接收通过了钢琴的组成声学打底。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
