当弦线受到变速运动的点荷载作用时，得到了理想弦线的横向速度。两种情况下进行评估，其中负载通过特征串速度加速或减速。随之而来的瞬时共振的检查和结果表明，作为负载速度通过串速度的奇异性产生的横向串速度，然后传播的串速度作为一个均匀的波。弦位移保持连续。
The transverse velocity of an ideal string is obtained when the string experiences a point load moving with varying speed. Two cases are evaluated in which the load either accelerates or decelerates through the characteristic string speed. The consequent momentary resonance is examined and the results show that as the load speed passes through the string speed a singularity in transverse string velocity is produced which then propagates at the string speed as a homogeneous wave. The string displacements remain continuous.
