1·According to entomologists, single locusts are quiet creatures, but when locusts are placed with others of their species, they become excited, change color, vibrate, and even hum.
根据昆虫学家的说法，单个的蝗虫是安静的生物，但是当它们和同类的其他蝗虫放在一起时，它们会变得兴奋，变色，振动，甚至嗡嗡叫。
2·So any electric current will then cause the fibers to vibrate. The fibers could act as a microphone or a speaker, depending on whether the vibrations were being recorded or amplified.
所以任何电流都会引起纤维振动，这时纤维就可以像麦克风或者话筒一样工作，当然这也取决于振动是否被记录或者放大。
3·The units at the base of each speaker vibrate, and these vibrations are then transmitted through the various glass elements above, each of which produces different frequencies of sound.
当每个音响单元的底座开始振动，上面各式的玻璃元件就会把这些振动传送，而在这个过程中每个元件就会产生不同频率的声音。
4·When the acoustic waves that make sound cause the fibres to vibrate it produces a corresponding electrical signal that can be detected.
当此类纤维振动导致声波出现的时候它们可以产生一定的能被捕捉到的电子信号。
5·Chemists have long known that atoms in a molecule vibrate at a particular frequency, depending on their overall molecular structure.
化学家们早就知道，在分子中原子以特定的取决于整体分子结构的频率振动。
