摘　　要：将作者在《大学物理》2004年第12期上的一篇文章的解法推广到弹性杆的强迫纵振动问题,并求解了两端系有集中质量的弹性杆的自由纵振动问题.We have extended the method used in our one end attached to a concentrated mass and another paper to the case of forced vibra.tion of an elastic rod end subject to a homogeneous boundary condition. We have also discussed free vibration of an elastic rod with two ends attached to concentrated mass.
