【摘要】 由于惯性运动的苛刻条件,生活中没有绝对的惯性运动,更多的是非惯性运动;因此,在生活中应用声波的多普勒效应时,须考虑声源和观察者运动的加速度.本文用时空结合的方法,描述出观察者或声源沿声波方向做匀变速直线运动的多普勒效应及其相应的表达式.结果表明,多普勒效应不仅与观察者相对声源的运动初速度有关,还与其相对加速度有关.更多还原

【Abstract】 Due to the harsh conditions of the inertia motion,no inertial motion in our daily life and non inertial motion is common.So,the application of the Doppler effect should take the acceleration of motion of the observer and sound source into consideration.In this paper,we use the method combining space and time to describe the Doppler effect of observer or sound source moving along the direction of the wave with certain acceleration.Combining mathematical graph and analysis to infer that the Doppler effect is not only associated with the speed of the observer to the sound source,but also related to acceleration of the observer to the sound source.更多还原
