在弦乐器上,弦同时存在着三种振动。即横振动、纵振动、扭转振动。其中,横振动是弦的主要振动形式,它可以由人的眼睛直接观察到,本文主要讨论弦的横振动。弹拨乐器弦的横振动包含两个不同形式的振动。一、由于手指将弦挑离其平衡位置。当手指离弦后,弦的弹性恢复力使弦产生弹回脉冲,并由于惯性越过平衡位置弹到另一边对应位置。所谓对应位置是指以平衡位置为对角线,以拨弦处 On a stringed instrument, there are three vibrations simultaneously in the string. That horizontal vibration, longitudinal vibration, torsion vibration. Among them, the transverse vibration is the main form of vibration of the string, it can be directly observed by the human eye, this article focuses on the transverse vibration of the string. The lateral vibration of a plucked string contains two different forms of vibration. First, because the finger will string off its balance position. When the finger is off the string, the elastic restoring force of the string causes the string to generate a bounce pulse and, due to inertia, bounces over the equilibrium position to the opposite position. The so-called corresponding position is to balance the position of the diagonal to the plucked place
