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 比较了云南菊头蝠和普氏蹄蝠飞行状态和悬挂状态下的回声定位声波，描述这2种蝙蝠的多普勒补偿效应，悬挂状态声波频率显著高于飞行状态，声脉冲时间和间隔时间显著长于飞行状态， fm带宽窄于飞行状态。
There are some intra - species differences in the echolocation calls of myotis daubentoni , myotis ricketti , myotis capaccinii , miniopterus schreibersii parvipes and pipistrellus abramus when they are in different state such as flying , being held , crawing and setting off . the intra - species differences of myotis daubentoni , myotis ricketti are most significant 栉鼠耳蝠、大足鼠耳蝠、毛腿鼠耳蝠、普通长翼蝠福建亚种和普通伏翼在飞行、手持、爬行和起飞等不同状态下的回声定位声波均具有一定差异。
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 对云南菊头蝠、大耳菊头蝠、普氏蹄蝠、双色蹄蝠的回声定位声波进行分析，描述其声波特征，是国内首次对这4种蝙蝠回声定位声波的报导，云南菊头蝠是中国特有蝙蝠，对其进行声波描述具有中国特色，为国际蝙蝠回声定位声波库的建立提供新的数据和资料。
In attempt to directly compare the sound response characters of the same bf neurons or different bf neurons and their interactive relation , the double recording microelectrodes were penetrated into two different neurons in iso - frequnency laminas or hetero - frequency laminas . taking advantage of frequency tonotopical arrangement in 1c of bats , it was explored how the neurons integrated different parallel processes of the same sound information . in the case of which , we hoped to explore the relation between the sound response characters of the central auditory neurons and neural modulation in background noise for the further understanding of the mechanism in the central auditory neurons extracting sound signals 本研究以大棕蝠( bigbrownbat , eptesicusfuscus )为模型，利用ic声调组构排列成同频层这一结构特点，突破单电极记录和检测神经元的方法，同时推进两单电极至一个同频层或两个同频层的两个不同神经元，试图从细胞水平直接比较两个具有相同和不同最佳频率的神经元声信号的加工处理特征、以及它们之间的相互关系，以期窥探它们在对同一声信号处理过程中的整合奥秘，并以此为基础分析和探讨背景噪声条件下中枢神经元声反应特征与神经调制的关系，以期进一步了解中枢听神经元声信号提取的机制。
The bat mother and its child were compared concerning their morphology and echolocating calls , and the change in morphology and echolocating calls , which happened as the young bat grew were discussed . the communicating behavior between the mother and the young was described and thus the calls played an important role in the communication between the mother and the young 对云南菊头蝠的母幼蝠进行形态和声波上的比较研究，探讨随着云南菊头蝠生长发育其形态和回声定位声波的变化，描述母幼的交流行为，确定其母幼交流的方式主要为声音。
