摘要
用数学分析法讨论了在弹性媒质中传播平面简谐波的质元的运动,得出了用波形曲线上点的切线斜率和质元振动的速度关系来确定质元速度情况的方法,并讨论了传播纵波的质元的疏密分布规律与波形曲线上各点切线斜率的关系。
A mathematical analysis on the motion of the mass elements in the simple harmonic wave is presented. A method perform the relations between the velocity of the mass elements and the gradient of the waveform is given. The relations between the distribution of the condensation of mass elements that transimiting the longitudinal waves and the gradient of the wavefore is discussed.
