摘要
杆的纵向振动是连续系统的内容,一个连续系统具有分布质量、分布弹性、分布阻尼。杆的纵向振动可用波动方程来描述,是用空间与时间坐标来描述的。运动方程是偏微分方程。
The longitudinal vibration of rod is one of the topics for a continuous system, that has distributed mass, distributed elasticity and distributed damping. The longitudinal vibration of rod is described by a wave e-quation,and the space and time coordinates,while its equation of motion is a partial differential equation.
