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 are 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.
