简谈理想玻色原子气体的BEC

本文描述了理想玻色气体的玻色一爱因斯坦凝聚（BEC）现象，讨论生成BEC现象的临界温度条件，从量子统计解释了BEC现象．对三维体系，指出了当分子间的平均距离火于分子热运动的德波罗意波长是就能产生BEC现象．从讨论BEC态的热容量可知当温度低于临界温度时，正常态的热容量产生突变即存在相变．

Brief Study on the Bose--Einstein Condensation of The Ideal Bose Atomic Gas

the Bose--Einstein Condensation （BEC） of the ideal Bose gas was described. The critic limit of the BEC was discussed and the BEC was interpreted on the basis of the quantum statistics. For three dimensional systems, it shows that the BEC occurred when the mean distance of the molecular shorter than the De Broglie wave length of the thermo motion of the molecular. By discussing the specific heat of the BEC state, it was known that specific heat has abruptness, i. e. , there was phase transition happening when the temperature lower than the critic temperature.
