| 摘要: |
| 应用计算机技术研究采自山西临汾的日本条螽[Ducetia japonica(Thunberg)]的鸣声特征。结果表明:日本条螽的鸣叫分起始阶段、低潮阶段和高潮阶段。低潮阶段的脉冲重复率为9Hz,高潮阶段的脉冲重复率为50 Hz。低潮阶段的主能峰频率为1.4 kHz,次能峰频率为2.4 kHz。高潮阶段的主能峰频率为1.8kHz,次能峰频率为1.6 kHz。日本条螽鸣叫的能峰主要分布频率为100 Hz~2.4 kHz,但在频率4.5kHz~5.0 kHz也具有较明显的能峰。 |

| Abstract: |
| The sound of Ducetia japonica Thunberg consists of three stages, initial stage, low tide stage and high tide stage. In sound spectra of song, the main peak frequency of low tide stage is 1.4 kHz, that of high tide stage is 1.8 kHz.The secondary peak frequency of low tide stage is 2.4 kHz,that of high tide stage is 1.6 kHz. |
