Dynamics of spin-glasses subjected to slow continuous changes of working
enviroment such as slow changes of temperature or interaction bonds
are studied based on scaling arguments and numerical simulations of
continuous bond changes.
Such perturbations lead to a glassy
stationary state where the age or domain size of the system
is pinned to macroscopic but finite values
due to competition between relaxation and chaos effects (rejuvenation).
Flutuation-dissipation relation is also pinned
to that of a finite age.
The scenario explains the anomalously weak cooling rate dependece
of spin glasses.
