On average, teachers using it increased the time they taught reading skills like funnies and vocabulary.

平均上，教师用它来增加教阅读技巧的时间，如：声学和词汇。

Focusing on the problem of the nature of the high velocity surface acousticsmode,we investigate the standard of judging which a wave is a surface wave,present the Green function of a pseudo-SAWand a longitudinal-wave headwave,thus developing the theory for generalized Green's function of surfaceexcitation of a piezoelectric crystal,with the hope to systematize this theory.

本文围绕压电晶体半空间上的高速表面声学模式热点问题，对表面波模式进行了界定，又发展了压电晶体表面激发的Green函数理论，给出了伪表面波及纵波头波的Green函数，从而形成更完整的压电晶体表面激发理论系统。

Both his mother and his wife were deaf, hence his interest in acoustics. Others had created working phones, but Bell gave us the first commercially practical telephone, as well as the metal detector and the graphophone, an improved version of the phonograph.

亚历山大-格雷厄姆-贝尔的母亲和妻子都是聋子，所以，他对声学很感兴趣，其他人研制了工作电话，而贝尔为我们送出第一个商业实用电话，和金属探测器以及改良版留声机——格拉福风留声机。

Surrounded and lifted up by the storied past or the harmonics of hand-me-down fiddles, banjos, mandolins, hammered dulcimers and guitars, each hardtack generation has been inspired and nurtured by the melodic expression of an ancient mountain region – Appalachia.

包围而且被传说上有名者举起越过或者现成小提琴、班卓琴、曼陀林、被槌打的德西马琴和吉他的和声学，每个硬面饼世代已经被远古山区域－阿帕拉契山区的有旋律表达激发而且养育。

The objective parameters, including fundamental frequency, Jitter , Shimmer, Harmonic to noise ratio, Normalized noise energy, and maximum phonatory time which were measured mainly on a sustained /i:/ with the Dr.

嗓音的客观检测：以/i：/音为样本，进行声学测试，测Jitter、Shimmer、Fo、NNE、HNR。测出MPT。结果(：1)嗓音的主观评价：总嘶哑度G在不同疾病组间有显著的差异(p.01)；除声带小结/声带息肉组间不能区分外，VHI-10在不同分组间有显著差异。

The headliner cover is made of a knit material that also serves as one of five layers of an acoustically designed headliner to help make the passenger compartment quieter.

The simulation of an muffler involved in hydrokinetics, structural dynamics and acoustics.

消声器的数值模拟涉及到流体动力学、结构动力学以及声学等多个学科的知识。

Acoustic Doppler Current Profilers is a new kind of flow measuring device widely used in hydrometry. It uses the principle of Acoustic Doppler instruments to measure flow velocity profile. A short time flow measurement, high resolution, good accuracy, integrity data and great information are the characters of ADCP.

多普勒测流仪是当前在水文行业推广的一种新型测流仪器，该仪器利用声学多普勒原理，测量水流速度剖面，具有测验时间短、分辨率高、精度好、资料完整、信息量大等优点。

The impersonally evaluation of the speech communication quality is an important problem in acoustics domain .
