Abstract :
We present in this paper analytical results for the pressure profile in an evacuated tube, when subject to two situations common to accelerator vacuum technology. The first case deals with a system presenting two different degassing rates along the tube length. The second part presents results for the time evolution of the pressure profile in a tube where a sudden and localized degassing occurs
