玻色-爱因斯坦凝聚和影响粒子态密度的因素

Bose-Einstein Condensation and the Factors of Affecting the Particle Density-of-state

本文讨论了在理想(无外势场)情形下,粒子的态密度与粒子运动空间的维度n及对能量的不同依赖关系,并在此基础上,讨论在有外势场的情形下,得出粒子的态密度与粒子运动空间的维度n,以及与外势场的性质之间的关系.

At first, this paper has discussed that the state density of particle relates to dimension n of particle space motion and different energy in ideal condition （there is not external potential field ）. On this basis , We also draw a conclusion that the particle density-of-state not only relates to the dimension of space motion but also the property of the external potential field.
