发声机制 meaning in Chinese

acoustic mechanism

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。
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。
