研究一端接简谐振源、另一端固定的弦在阻尼介质(空气)中的稳态振动及阻力系数的测定。结果表明在考虑了媒质阻尼的情况下，波节处的振幅将不为零。在理论上避免了无穷大振幅的出现，在实验上可通过测量波腹和波节处的振幅计算阻力系数以及在阻尼介质中的驻波波腹点和波节点的位置相对于自由空间的纯驻波状态时的波腹点和波节点的位置的偏离量。

The damping coefficient is determined by means of steady state vibration of a stretched string in the air medium,whose one end is attached to a harmonic vibrating source and the other end is fixed.The results show that considering damping of medium,the ampli-fiers at the positions of wave nodes are not zero.The infinite amplifier is avoided in theory. The damping coefficient and the deviations of the positions of the loops and nodes of stationary wave in damping medium relative to in free space can also be calculated by measurement of am-plifiers at the positions of a loop and a node.
