有一天,一个11岁的小女孩来到蜂场玩。她发现许多蜜蜂聚集在蜂箱上,翅膀没有煽动,却仍然嗡嗡的响个不停,于是想起教科书和《十万个为什么》上关于蜜蜂等昆虫发声的原理,她不由得产生了怀疑:为什么书上说蜜蜂的嗡嗡声来自于翅膀的振动,每秒高达200次,如果翅膀停止振动,声音也就应该停止了。可现在蜜蜂的翅膀已经停止振动却仍然嗡嗡响个不停,这声音到底是从哪里来的呢? One day, an 11-year-old girl came to the apiary to play. She found that many bees were gathering on beehives and their wings were not shaken, but they still kept buzzing. They remembered the textbooks and the principle of the sound of bees and other insects in the “One Hundred Thousand Reasons”. She could not help wondering why: Why the book? The bee’s buzz comes from the vibration of the wings, up to 200 times per second. If the wings stop vibrating, the sound should stop. But now the wings of the bees have stopped vibrating and still buzzing. Where did this sound come from?
