摘要：
This paper is concerned with damped linear dynamical systems, a subject of interest to Tom Caughey. Two approximating schemes for such systems are described. One scheme, due to Rayleigh, approximates the damping, while the second approximates both the damping and the stiffness. Both types of approximation are applied to an example.
