The echolocating calls in the state of fly were compared with those in the state of hang in two kinds of bats, r. yunanensis and h. pratti, and the doppler compensation effect was described. the analyzing result indicated that the frequency in hang was higher that that in fly, the duration and interpulse duration in hang were longer than those in fly, and the fm bandwidth in hang was narrower than that in fly
比較了雲南菊頭
蝠和普氏
蹄蝠飛行狀態和懸掛狀態下的回聲定位聲波,描述這2種蝙
蝠的多普勒補償效應,懸掛狀態聲波頻率顯著高於飛行狀態,聲脈沖時間和間隔時間顯著長于飛行狀態, fm帶寬窄于飛行狀態。
The characteristics of echolocating calls of r. yunanensis, r. macrotis, h. pratti and h. bicolor were analyzed and described ; it is the first time in china to do this kind of research. r. yunanensis is native to china, so the research on its echolocation is characteristic of china and provides new data to set up the echolocating calls database in the world
對雲南菊頭蝠、大耳菊頭蝠、普氏蹄蝠、雙色蹄蝠的回聲定位聲波進行分析,描述其聲波特徵,是國內首次對這4種蝙蝠回聲定位聲波的報導,雲南菊頭蝠是中國特有蝙蝠,對其進行聲波描述具有中國特色,為國際蝙蝠回聲定位聲波庫的建立提供新的數據和資料。
