摘　　要：通过对盛水容器中的水加热至沸腾过程的详细观察,揭示了水沸腾前后的声音差异。水沸腾前,气泡上浮引起水的振动、容器壁的共振和容器底干烧部分触水收缩的振动,导致响声较大;而水沸腾时,气泡连续冒出并上浮,导致这些振动减弱,响声较小。Through detailed observation of the process of heating water in a container until it boils,the difference in sound before and after water boils is unveiled.Before water boils,the rising bubbles give rise to the vibration of water,the resonance of the container wall and the vibration of the dry-burned part of the container bottom contracting upon contact with water,resulting in a relatively loud noise.When water boils,bubbles continuously emerge and rise,leading to the weakening of these vibrations and the relatively small noise.

关 键 词：热现象 沸腾 声音 振动
