Since Einstein predicted the phenomenon of Bose-Einstein Condensation in 1924, more physical scientists have tried to realize it, but they didn’t break through until 1995. In this paper, the characteristics and conditions of BEC are introduced first, and then the exploration course is presented. Based on these studied, the realizing techniques of BEC is proposed, including Laser Refrigeration Technique, Ion Trapping of Magnetic Capture, Evaporative Cooling Technology and Measurement Technology of BEC, etc.

Bose–Einstein condensation in a gas has now been achieved. Atoms are cooled to the point of condensation using laser cooling and trapping, followed by magnetic trapping and evaporative cooling. These techniques are explained, as well as the techniques by which we observe the cold atom samples. Three different signatures of Bose–Einstein condensation are described. A number of properties of the condensate, including collective excitations, distortions of the wave function by interactions, and the fraction of atoms in the condensate versus temperature, have also been measured.
