摘要: 数学物理方法的一些学习指导书或教科书上给出了两种转动弦的波动方程,但没有考虑Coriolis力的影响,其讨论方法存在不正确(竖直转动重弦)或不全面(水平转动轻弦)之处.重新讨论了两种转动弦的波动方程及其求解问题.

关键词: 转动弦, 波动方程, Coriolis力

Abstract: Wave equations for two different types of rotating strings are given in some reference books or text- books of methods of mathematical physics, but the effect of the Coriolis force is not taken into account. There-fore the discussions are incorrect (for vertical rotating heavy string) or incomplete (for horizontal rotating light string). These wave equations are re-derived and their solutions are discussed.

Key words: rotating string, wave equation, Coriolis force
