| 单词 | 声波 |
| 释义 | 〔resonator〕A hollow chamber or cavity with dimensions chosen to permit internal resonant oscillation of electromagnetic or acoustical waves of specific frequencies.共振腔：具有容积的空室或空腔，可允许在某一频率下的电磁波或声波产生内部共振振荡〔impinge〕Sound waves impinge on the eardrum.声波撞击着耳膜〔microphone〕An instrument that converts sound waves into an electric current, usually fed into an amplifier, a recorder, or a broadcast transmitter.扩音器，麦克风，话筒：将声波转变成电流的工具，通常接至扩音器，录音机或广播发射机上〔phonoreception〕Perception of or response to sound waves.感声，音感受：对声波的感觉或回应〔sonoluminescence〕The production of light as a result of the passing of sound waves through a liquid medium. The sound waves cause the formation of bubbles that emit bright flashes of light when they collapse.声光效应，声致发光：由于声波从液体媒质中经过而产生的光。该声波导致了泡沫的形成，这些泡沫破裂时发出明亮的闪光〔echo〕To repeat (a sound) by the reflection of sound waves from a surface.发出回声：表面反射声波而重复的声音〔subsonic〕Of less than audible frequency.亚声的：小于可听见之声波频率的〔baffle〕A partition that prevents interference between sound waves in a loudspeaker.隔音板：在扩音器中防止声波相互干扰的隔离装置〔pickup〕The reception of light or sound waves for conversion to electrical impulses.光波的接收：为转变为电子脉冲的光波或声波的接收〔diffuser〕A device, such as a cone or baffle, placed in front of a loudspeaker diaphragm to diffuse the sound waves.扬声器纸盒：一种装置，例如锥形体或反射板，放在扬声器膜前面，用来散射声波〔echo〕Repetition of a sound by reflection of sound waves from a surface.回声：因表面反射声波而引起的声音重复〔high〕Having a pitch corresponding to a relatively large number of sound-wave cycles per second:高音的：声调与每秒较大数量的声波循环相对应的：〔sonar〕A system using transmitted and reflected underwater sound waves to detect and locate submerged objects or measure the distance to the floor of a body of water.声纳：一种系统，通过利用传送或反射的水下声波，来探测或定位水下物体或者测量某一水域的深度〔midrange〕The middle part of an audio frequency.中声频，中频：声波频率的中间部分〔rarefaction〕A decrease in density and pressure in a medium, such as air, caused by the passage of a sound wave.稀薄化：介质中密度和压力的下降，例如在空气中，由于声波的穿越而发生〔reverberate〕To be repeatedly reflected, as sound waves, heat, or light.被反射：被重复反射，如声波、热或光〔supersonic〕Of or relating to sound waves beyond human audibility.超声波的：人无法听见的声波的或与超声波有关的〔diaphragm〕A thin disk, especially in a microphone or telephone receiver, that vibrates in response to sound waves to produce electric signals, or that vibrates in response to electric signals to produce sound waves.膜片，振动板：一种薄的圆盘（尤其是在麦克风和电话收话器里那种）响应声波振动产生信号或者响应电信号振动产生声波 |
