声波频率 meaning in Chinese
frequency of sound wave
Examples
- Acoustic frequency sounding
声波频率测深 - The effects of observing scale on the measurements of acoustical velocity were studied by ray theory and equivalent medium theory
分析了声波频率影响传播速度的机理，给出了不同温度不同压力条件下声波速度随频率变化关系的实例。 - Sound waves from the iceberg had a frequency of around 0 . 5 hertz , too low to be heard by humans , but by playing them at higher speed the iceberg sounded like a swarm of bees or an orchestra warming up , the scientists said
科学家说，冰山传来的声波频率约为0 . 5赫兹，因为频率过低人类听不到，但是若是以较快的速度播放，冰山听起来就像是成群的蜜蜂声或是管弦乐队在热场。 - Sound waves from the iceberg had a frequency of around 0 . 5 hertz , too low to be heard by humans , but by playing them at higher speed the iceberg sounded like a swarm of bees or an orchestra warming up , the scientists said
据路透社11月24日报道，科学家表示，从这座冰山传来的声波频率大约为0 . 5赫兹，远远没有达到人耳的听力范围。但科学家加速播放声波录音后发现，这座冰山能发出一种类似大群蜜蜂的嗡嗡声或者管弦乐队演奏前热身的声音。 - 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。
