摘要：

This paper examines critically the practice of using first-order sensitivities for extrapolation to predict the effect of structural changes. A quality criterion, based on the Cauchy ratio test for convergence of infinite series, is suggested to examine the liability of systems to perform poorly under extrapolation. The efficacy of this approach is demonstrated on a simple numerical example.
