摘要：
In the technical note a single-degree-of-freedom system with stationary random temporal variations of its stiffness is considered. The problem of short-term instability is studied. The analysis is based on a parabolic approximation of the randomly varying apparent stiffness within the negative domain achieved by invoking a Slepian process model.
