大蝙蝠

The six species of bats includes Myotis frater,Ia io,Myotis myotis luctuosus,Myotis daubentoni,Myotis fimbriatus and Murina leucogaster.Pearson coefficient (one of correlation analysis methods in SPSS10.0 software)has been adopted to analyze the interspecific relationship between the dominant frequency and body size.

测定了6种蝙蝠科蝙蝠：长尾鼠耳蝠、南蝠、大鼠耳蝠、水鼠耳蝠、毛腿鼠耳蝠、白腹管鼻蝠的回声定位声波特征及体型参数。

They include little brown bats, northern bats, tricolored bats, Indiana bats, small-footed myotis and big brown bats.

它们包括小棕蝠，蝙蝠北部，三色旗的蝙蝠，蝙蝠印第安纳，小足鼠耳蝠，大棕蝠。

There is obvious negative correlation between dominant frequency and bodily size in Rhinolophidae, Vespertilionidae and Hipposideridae.

菊头蝠科、蝙蝠科和蹄蝠科回声定位信号能量最大处频率与体型呈明显的负相关，蝙蝠科相关性最好，其次为蹄蝠科，较差的为菊头蝠科；能量最大处频率与前臂长的回归线表明：对于前臂长相同的蝙蝠，蹄蝠科的能量最大处频率远远高于其它两科，菊头蝠科高于蝙蝠科。

The echolocation signals of Rhinolophidae and Hipposideridae are both long CF-FM with 1 harmonic and narrow FM bandwidth. But Rhinolophidae has longer duration, higher duty cycle and lower dominant frequency than Hipposideridae. All the echolocation signals of Vespertilionidae are short FM with 2-6 harmonics and wide FM bandwidth. Vespertilionidae has shorter duration and lower duty cycle than the other two families. There are obvious differences in dominant frequency between different species in this family.

菊头蝠科和蹄蝠科回声定位信号均为长CF-FM型，一般具有1个谐波，调频带很窄，但菊头蝠科的持续时间和能率环明显高于蹄蝠科，蹄蝠科能量最大处频率高于菊头蝠科；蝙蝠科回声定位信号均为短FM型，具有2～6个谐波，持续时间和能率环比其他两科低，调频带很宽，能量最大处频率在种间变化较大。

"The male who ejaculates the greatest number of sperm may win at this game, and hence many bats have evolved outrageously big testes," Pitnick said.

Pitnick认为：睾丸能射出最多精子数量的雄性蝙蝠在交配中才有可能胜出，因而许多蝙蝠通过进化，都有了超常大的睾丸。

More dreadful being still has the bat attracting animal blood specially , these bats are all comparatively big.

更可怕的是还有专门吸动物鲜血的蝙蝠，这些蝙蝠都比较大。

And white-nose syndrome could threaten already endangered species, such as Indiana bats, tiny creatures with pink noses that flutter from the north-east to the mid-Atlantic, and the big-eared bat, the official state bat of Virginia.

而且白鼻综合症还会威胁到那些已经濒临灭菌的蝙蝠物种。比如体型较小，鼻子粉嫩，在太平洋沿岸的东北部和中部之间迁徙的印第安纳蝙蝠，还有维吉尼亚的官方蝙蝠，大耳蝙蝠。

The characteristics of recovery cycles in inferior collicular neurons of leaf-nosed bat and effect of the recovery cycle on the following pulse repetition rate were studied using mimic CF-FM sound stimuli emitted by free flying bat. 93 IC neurons were obtained from IC of five bats with normal hearing.

为探究恒频-调频蝙蝠下丘神经元恢复周期特点及其对声脉冲跟随率的影响，实验采用模拟的大蹄蝠自然状态下的恒频-调频发声信号为声刺激，在5只听力正常的大蹄蝠上记录了下丘神经元的声反应和恢复周期（n = 93）。

The flying fox is not a fox at all.

大蝙蝠一点也不是一只狐狸。

A big brown bat flew past,Did the big black fly past faster than the big brown bat flew past?

一只大的棕色的蝙蝠也飞过去了。大的黑色的蝙蝠飞得比大的棕色的蝙蝠快吗？

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
