2.
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。
3.
All the results in sub - oscine passerine will provide effective resources for the mechanism of avian vocal and the active character of nxiits 以上这些结果将为进一步了解鸟类发声机制及鸣管神经支配特性的研究提供新的认识。
4.
Whilst many do winter here , their numbers are swollen in february and march by northbound migrants ( and presumably in late autumn , too , when there are just too many exciting passerines to look at 虽然也有度冬的族群，但在二三月间，明显的由于北迁过境族群的加入数量膨胀许多。
5.
Psittacula agapornis ) , oscine passenon ( emberiza rutila ) and the vocalizations of sub - oscine passerine ( melopsittacus undulates , psittacula agapornis ) after sectioning nxiits were recorded by sharp gf - 6060 recorder . cooledit2000 , an acoustic analyzing software , was used to produce the original wave and it ' s expanded time windows , sonograms , spectrums and power static histograms . to distinguish the acoustic differences of their natural vocal and to find the changes of sub - oscine passerine ' s song after sectioning nxiits , the above results is acoustically analyzed and compared , expecting to provide some advantage to further explaining the mechanism of vocal production 本实验以非鸣禽(家鸽、家鸡) ，亚鸣禽(虎皮鹦鹉、牡丹鹦鹉)以及鸣禽(栗? )为实验材料，记录其正常叫声以及亚鸣禽断nxiits后的叫声，用cooledit2000声音处理软件制出原始信号及其展开图，声图，频率谱图以及能量统计分布图，并对所得结果进行声学比较分析，以期得到鸣禽、亚鸣禽及非鸣禽叫声在声学特性上的差异，以及亚鸣禽在断神经后叫声的声学变化，旨在为进一步解释其发声机制提供帮助。
6.
Compared with non - passerine , they appeared longer syllable length , higher basic frequency and more viable frequency ranges . though the amplitude modulation properties enhanced their vocal production , the type of syllable is still stable and less of variety . so the phrase consisted of syllables are comparatively few and changes of the tone are relatively less 且表现出很强的频率调制特性和特有的幅度调制特性，相对的音节时程比较长，基频较高且频率变化范围较大，所特有的幅度调制特性更增加了其控声的能力，但其音节的种类仍很单一，缺乏变化，由音节所组成的句型较少，音调变化幅度不大，因此，其叫声质量尽管较非鸣禽有所改善，但相对鸣禽而言却又远远不如。
7.
The calls of non - passerine are some kinds of monotonous dull vocalizations with the characteristics of low and deep frequency , single syllable , low basic frequency and with no ability of modulation in frequency and amplitude . most of the calls are monotonous and low quality mainly based on the basic song . compare the vocal of sub - oscine passerine with non - passerine , they have some similar aspects , but the former possesses of stronger capability of vocal control 非鸣禽的叫声低沉而单调，音节种类单一，基本音频率低，缺乏频率调制以及幅度调制的能力，叫声的品质因数很低，不悦耳，大多为以基本音为主的单音调低音品叫声，亚鸣禽的叫声与非鸣禽近似，但在控声能力方面又有所提高。
8.
The modulation of sound properties over a wide range of time scales is one of the most obvious characters of oscine passerine ' s vocal , whose song contains many different kinds of syllables that consist of many more multiple song phrases . in oscine passerine , ipsilateral projections of ra to nxiits innervates the ipsilateral syringeal muscles exactly , and thus they have strong ability of vocal control with variable tones , high frequency and higher lever of quality . as a result , the songs sound well 鸣禽鸣啭的最大特点之一便是其单次鸣唱时间长，鸣唱所包含的音节数量和音节种类繁多，因而由这些音节所组成的句型结构也是复杂多样富于变化，且由于nxiits严格的侧别控制(每一侧核团只支配同侧鸣肌) ，使其具有更强的控声能力，其鸣声音调变化幅度大，频率高，品质因数大，音色好，因而其鸣声也悦耳动听。
