elastic string

in this paper, we re-examine the linear theory of wave propagation through an elastic string under uniform tension or a slender elastic rod from a perspective that focuses on the flow of mechanical energy and mechanical momentum.

本文通过机械能、机械动量流动的观点，依据波传播的线性理论，审查了在一个绷紧不变的弹性弦上或在一个纤细弹性杆中传播的脉冲波。
