When accumulation minus ablation, the net budget, is zero over a long period, the glacier is in a steady state, accumulating new snow in its upper reaches and constantly moving downslope to the lower reaches, where ablation takes place.  4, fiche 1, Anglais, - steady%20state

The ice sheet is said to be in(dynamical) equilibrium if each column of ice gains as much as it loses. The mass balance integrated over the ice sheet must then be zero. The steady state concept is a theoretical concept, which will hardly ever be met because accumulation and ablation are highly variable on short time scales and the flow varies on much longer time scales. So only under a constant climate of say ten thousand years a real steady state will be reached.  2, fiche 1, Anglais, - steady%20state

Si un glacier est stationnaire au cours des ans (c'est-à-dire si sa forme et son volume ne varient pas) et si les bilans spécifiques sont également stationnaires, on peut affirmer que les vitesses en des points donnés (fixes dans l'espace) sont toujours les mêmes. Le mouvement est permanent, ou [...] le glacier a atteint un état de régime.  1, fiche 1, Français, - %C3%A9tat%20de%20r%C3%A9gime

When the temperature sinks on a cold winter's day water vapour becomes water and water becomes ice. These so-called phase transitions and the changed states of matter can be roughly described and understood with classical physics. What happens when the temperature falls is that the random heat movement in gases, liquids and solid bodies ceases. But the situation becomes entirely different when the temperature sinks further and approaches absolute zero,-273. 15°C. In samples of liquid helium what is termed superfluidity occurs, a phenomenon that cannot be understood in terms of classical physics. When a liquid becomes superfluid its atoms suddenly lose all their randomness and move in a coordinated manner in each movement. This causes the liquid to lack all inner friction : It can overflow a cup, flow out through very small holes, and exhibits a whole series of other non-classical effects. Fundamental understanding of the properties of such a liquid requires an advanced form of quantum physics, and these very cold liquids are therefore termed quantum liquids...  2, fiche 2, Anglais, - quantum%20liquid
