音乐可以陶冶人的情操 ,也可以使气温降低……声波确实可以输送热量。对于音乐家来说 ,声音首先是旋律。对于物理学家来说 ,它则主要是一种运动 :传播声波的介质分子的振动和介质各点交替的压力变化。声波的特点是它的平衡点两侧每个分子的振荡运动 ,因为这种振荡是逐渐地传播? Music can cultivate people’s sentiments, but also can make the temperature lower ... ... Sound waves can indeed deliver heat. For musicians, the sound is melody first. For physicists, it is mainly a movement: the vibration of the media molecules that propagate the sound waves and the alternating pressure changes at various points in the media. The characteristic of an acoustic wave is the oscillatory motion of each molecule on both sides of its equilibrium point, because this oscillation propagates gradually?
