| 摘 要： | 应用计算机技术,对黄树蟋Oecanthus rufescens Serville雄性鸣声的时域及频域特征进行了分析.结果表明,黄树蟋雄性鸣声的时域波形由规则的脉冲组序列构成,通常含有11个脉冲组.每个脉冲组持续时间约为0.230 s,脉冲组间隔约为0.330 s,脉冲组重复率约为0.64次/s,每个脉冲持续时间约为0.008～0.012 s,脉冲重复率约为23次/s,脉冲间隔约为0.004 s.鸣声频率的主频带范围是2.2～4.4 kHz,主能峰频率约为3.3 kHz.

| Abstract: | Male calling song of Oecanthus rufescens Serville,1838 is analyzed in computer technology.Oscillographic analysis shows that the chirp rhythm of Oecanthus rufescens is highly regular;whole chirp sequence includes 11 chirps.A chirp of the songs,lasting about 0.230 s,consists of 13～17 pulses.Interchirp interval is about 0.330 s,chirp repetition rate is about 0.64 /s. One pulse of the chirps continues about 0.008～0.012 s.Pulse interval is about 0.004 s,pulse repetition rate is about 23 /s.It has a main frequency within the range 2.2 to 4.4 kHz,and the peak carrier frequency is about 3.3 kHz. |
