In recent years, the experimental studies of Bose-Einstein condensation (BEC)have obtained fast development, and achieved a series of significant experimental progress. In this review, we will mainly introduce some experimental results of BECs and its recent progress, which include: the realization of alkali atomic (~7Li,~(23)Na,~(41)K,~(85)Rb,~(87)Rb 和~(133)Cs)BEC with positive and negative scattering lengths, the realization of ~1H, ~4He and ~(174)Yb atomic BEC, and the realization of all optical BEC, BEC in microtrap and BEC in lower dimension, even the realization of molecular BECs and condensation of Fermionic atom pairs as well as some applications of ultracold BEC condensates, and so on.

We present recent results on atom optics with Bose–Einstein condensates obtained at MIT. These results demonstrate the flexibility of micro-fabricated atom traps (atom-chips) and the interaction of Bose–Einstein condensates with surfaces through normal incidence quantum reflection.

Investigations on the Bose-Einstein condensation(BEC)have made great progress in recent years,and a lot of important results have been obtained.This paper gives a brief introduction to the new progress on BEC,which include five fields:(1)the BEC realization of alkali atom(7Li,23Na,41K,85Rb,87Rb and 133Cs);(2)the BEC realization of 1H,4He and 174Yb atom;(3)the BEC realization of all optics and double trap;(4)the BEC of molecule and Fermi atom pairs;(5) Bose-Einstein condensation in the solid state.The applications and expectation of BEC have also been summarized.
