Nocturnal mouselike mammal with forelimbs modified to form membranous wings and anatomical adaptations for echolocation by which they navigate.

夜间活动行似老鼠的哺乳动物，其前肢进化成膜状翅膀，其生理特征适于回声定位并借此导航。

A wide variety of new and established terms are discussed, including absolute zero, anaphylaxis, cryptography, echolocation, game theory, Kuiper belt, mitochondrion, Munchausen syndrome, quantum mechanics, and refraction.

各种新的，并设立条件进行了讨论，其中包括绝对零度，过敏反应，加密，回声定位，博弈论，柯伊伯带，线粒体， Munchausen综合徵，量子力学，和折射。

Wavelet analysis because of its good retractility has become an advantaged tool in signal analysis field. We provide a new valid way for studying the echolocation calls of bat by using this tool.

而小波分析则突破了传统的傅立叶分析方法，利用其在时域和频域上同时具有的良好的局部性，成为信号分析的一个有利的工具。

The sibship of the three families was concluded from echolocation signals. There is very close sibship between Rhinolophidae and Hipposideridae, which possibly evolved from the same original group. Vespertilionidae is an isolated group with little affinity to Rhinolophidae and Hipposideridae, probably evolving from another original group.

回声定位信号特征推断出三科蝙蝠之间的亲缘关系：菊头蝠科与蹄蝠科有很密切的亲缘关系，很可能由同一原始种群进化而来；蝙蝠科是一独立的种群，与菊头蝠和蹄蝠的亲缘关系较远，可能由另一原始种群进化而来。

The vampire bat not only sucks blood, possesses infallible echolocation skills and flies better than most stealth bombers - it can walk. Make that run.

吸血蝙蝠不仅会吸血，它还拥有精确的回声定位技能，它的飞行技术胜过大多数隐形轰炸机，它能走善跑，跃过田野的速度不比你差。

Other moths in the families Noctuidae and Arctiidae have developed membranes that sense bats' echolocation and enable them to take evasive action, flying in a loop or dropping quickly out of the bat's flight path when they detect its presence.

夜蛾科和灯蛾科中其他种类的蛾子身体上长出了隔膜，可以感知蝙蝠发出的定位声，从而可以采取逃避行动。当发觉蝙蝠出现时，这些蛾子便作环状飞行，或者快速下降，逃出蝙蝠的飞行路线。

"Bat:any of various nocturnal flying mammals of the order Chiroptera, having membranous wings that extend from the forelimbs to the hind limbs or tail and anatomical adaptation s for echolocation, by which they navigate and hunt prey."

蝙蝠：一种翼手目的夜间飞行的哺乳动物，它们具有能从前肢伸到后肢或尾巴的膜状翅膀，其生理结构能够靠声波定位，并以此导航和捕食。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
