| 摘 要： | 本文对北京非洲蝼蛄(G.africana.)的鸣声特点进行了分析.非洲蝼蛄的鸣声类似由调幅单音节组成的哨声.单音节的频谱特性基本相一致,其载波的主峰频率(MPF)调谐度(Q_(3dB))和MPF下降20dB的带宽分别为2539Hz、17.3和479Hz.但是哨声和单音节的周期是不均一的.在由302个哨声组成的鸣声段中,哨声周期和每个哨声内单音节平均周期的主要分布区分别为115-225ms和12.90-15.75ms.这些结果可能为蝼蛄声诱捕装置的生物原型和数学模型的研究提供某些依据.

SONG CHARACTERISTICS OF MOLE-CRICKET |

| Abstract: | In this paper,the song charcteristics in the Beijing mole-cricket(G.africa-na.)are analysed.The calling song of G.africana.is similar to the whistle that consists of amplitude-modulated syllable.The spectral property of the syllable is basically consistent. For a syllable, the main peak frequency(MPF)of carrier wave,the tuning sharpness (Q3dB) and the bandwidth at level 20 dB below the MPF is 2539 Hz,17.3 and 479 Hz,respectively.But the whistle period and the syllable period are non-homogeneous. In song section consisting of 302 whistles, the main distributive range of the whistle period and of the mean period of the syllable in each whistle is 115-225ms and 12.90-15.75 ms,respectively.These results may provide some information for study of the biological prototype and the mathematical model in sound equipment luring mole-crickets. |
