METHOUS: An aqueous extract of Rhizoma menispermi, an alcohol purified extract named phenolic alkaloids of menispermum dauricum and Rhizoma menispermi polysaccharide were isolated and purified by using the three-step method.

用三步法初步分离、纯化北豆根提取物，得到北豆根水提液(aqueous extract of rhizome menispermi， RMAE)、醇提液的初步纯化产物蝙蝠葛酚性生物碱(phenolic alkaloids of menispermum dauricum， PAMI)和北豆根多糖成分(rhizome menispermi polysaccharide， RMP)。

Finally he slowed down and all the other bats excitedly milled around him.

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。

It has been found that certain bats emit squeaks and by receiving the echoes, they can locate and s teer clear of obstacles------or locate flying insects on which they feed.
