The principle of Bose\|Einstein Condensation(BEC) is outlined.The great contribution of E.A.Connell,C.E.Wieman and W.Ketterle who shared the 2001 Nobel Prize in Physics,in creating the world's first Bose\|Einstein Condensate is described.New progress in their studies of BEC physics and atomlasers is reviewed,as well as further prospects of for the applications of BEC.

The q-deformed Bose–Einstein distribution is used to study the Bose–Einstein condensation (BEC) of a q-deformed Bose gas in random box. It is shown that the BEC transition temperature is lowered due to random boundary conditions. The effects of q-deformation on the properties of the system are also discussed. We find some properties of a q-deformed Bose gas, which are different from those of an ordinary Bose gas. Similar results are also shown for q-bosons confined in a harmonic oscillator potential well.
