摘　　要：用Laplace变换法求解了弹性杆的两类纵振动问题,其中一类是两端具有齐次边界条件的振动问题,另一类是由两种材料连接而成的杆的振动问题.Two problems of the longitudinal vibration of an elastic rod, one of which is vibration of the a rod with homogeneous boundary conditions and the other is vibration of the a rod joined together with two materials, are solved by Laplace transform.

关 键 词：弹性杆 振动 齐次边界条件 LAPLACE变换
