声波的造句大全
- 造句1：超声波英 文：ultrasonic waves

- 造句3：但是，这种装置上的麦克风和芯片在收集接收到的声音后，就会发出一种反向声波，从而消掉钻牙的声音。英 文：But the microphone and chip in the device sample the incoming sound and produce an inverted wave that cancels out just the sound of the drill.
- 造句4：对肝脏作的超声波检查英 文：investigation of the liver by ultrasound
- 造句5：每片玻璃都有一个自然的共鸣频率——在此速度下，如果受到碰撞或者由某种刺激物打扰，它就会震动，如声波——地球上其他物质也是如此。英 文：Every piece of glass has a natural resonant frequency—the speed at which it will vibrate if bumped or otherwise disturbed by some stimulus, such as a sound wave—as does every other material on Earth.
- 造句6：研究人员按照可天宁含量水平将受访人群分成了高、中、低三组，并利用超声波来检查受访者主动脉与颈部动脉的血管壁厚度。英 文：They divided the children into groups with high, intermediate and low cotinine levels. Ultrasound was used to measure the thickness of the aorta and of the carotid artery in the neck.
- 造句7：在几周内，你可能还不能够通过声波图或者多普勒超声听到婴儿的心跳，但当你最终听到时，那快速的断断续续的节奏巩固你身体里有个小生命的证据。英 文：While you may not be able to hear the heartbeat through a sonogram or Doppler for a few weeks yet when you finally do the rapid staccato beats will be concrete evidence of the life inside you.
- 造句8：回声测深仪是用来测量水深的一种声学测量设备，其以水中超声波的传播速度为确定条件，利用发射波与反射回波时间差来测量水深。英 文：Echo Sounder is a kind of acoustic measuring depth equipment, which can measure depth with the time between transmitted wave and echo on condition in which the speed of ultrasonic is fixed.
- 造句9：介绍了自行研制的圆柱形多自由度超声波电动机的结构、驱动原理和输出性能。英 文：The construct, driving principle and output performances of the cylinder type ultrasonic motor with multi-degree of freedom were presented.
- 造句10：回声测深仪是用来测量水深的一种声学测量设备，其以水中超声波的传播速度为确定条件，利用发射波与反射回波时间差来测量水深。英 文：Echo Sounder is a kind of acoustic measuring depth equipment, which can measure depth with the time between transmitted wave and echo on condition in which the speed of ultrasonic is fixed.

【声波】的拼音及解释
解释
声振动在弹性介质中的传播过程。是传递声能的形式。在气体和液体中传播的声波是纵波，在固体中传播的声波有纵波也有横波。按振动频率高低，有超声波、可听声波和次声波。
