In order to detect the nonlinear determinism, the method of surrogate is employed. The null hypothesis that a real system response is from a stationary Gaussian linear process distorted by an invertible, static, nonlinear measurement function is made and tested.

采用替代数据法对实际房间声学系统的非线性确定性进行检测，假设实际系统响应是由平稳高斯随机过程经可逆、静态的非线性函数变换而得到，然后对该假设进行检验。

of A Dissertation on Chinese Traditinal Music Theory Chinese Dong Xiao Flute Music Culture: A Study Based on previous studies (particularly the findings and methods derived from archaeology, ethnology, the study of temperament, organology and acoustics), this dissertation endeavours to conduct a thorough and systematic investigation of the music culture surrounding the Chinese end-blown flute dongxiao.

中国洞箫音乐文化研究本文在以往学者研究成果的基础上，借鉴与本课题有关的考古学、民俗学、律学、乐器学、声学之成果与研究方法，对中国洞萧。。。

The results showed that the acoustic structures of non-passerine, sub-oscine passerine and oscine passerine\'s songs have significant differences.

结果表明，非鸣禽、亚鸣禽及鸣禽叫声的声学结构具有很大的差异性。

In Fabry-Pabry quantum structure, thetransmission coefficient show approximate periodicity as a function of geometric param-eters. The quantized thermal conductance does not appears due to the fact that hard-wallboundary conditions are applied in the structure.

应用散射矩阵方法，研究了低温下双缝量子结构和法布里-帕罗量子结构中的声学声子弹道输运和热导性质，计算结果表明：由于声子在输运过程中经过多重反射，这两种量子结构中的透射系数和热导都很小。

In this case, different gases ensure different acoustic responses with values of approximately 50 ppm.

这种情形下，不同的气体肯定有不同的声学反应，反应值大约在百万分之五十。

The acoustic modes of phonons dispersion relation are probability of the vector q , and their group velocities in the [001] direction are vL = 5.1k m /s and vT = 3.6 km /s, respectively.

声子谱中的声学模式在低频区与波矢成线性关系的，它们沿[001]方向声速分别为vL = 5.1k m /s和vT = 3.6 km /s。

He was born in 1921 and once studied in the Guangdong Provincial art School.

在声学中，他研究了声的传播和音乐的和谐与不和谐。

Instead of blasting music and announcements from an omnidirectional public-address system, directional loudspeakers -- or Audio Spotlight systems , as Holosonics calls them -- make sound audible only in certain designated locations.

不同于震耳欲聋的音乐和全方位播音系统，导向扩音器或者是全方位应用声学公司所称的音频聚光灯系统只在某些指定地点才让人们听到声音。

In order to acquire the accurate transmitted time of sound wave in power plant furnace in acoustic pyrometry, the time delay estimation of weak sound signal under the condition of strong noise is studied.

为了在电站锅炉声学测温中获得准确的声波飞渡时间，针对强噪声环境下弱信号检测问题，研究了声信号的时间延迟估计。

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。
