摘要翻译:
在本文中,我们证明了对于非理想玻色气体,在转变温度上存在一个上限,在该上限上,无论施加什么压强,玻色-爱因斯坦凝聚都不能发生。对一些实际玻色气体的这种上限进行了估计。这一结果暗示超导体的转变温度也可能存在一个上限。

英文摘要:
In this paper we show that for a non-ideal Bose gas there exists an upper limit on the transition temperature above which Bose-Einstein condensation cannot occur regardless of the pressure applied. Such upper limits for some realistic Bose gases are estimated. This result implies that there may also exist an upper limit on the transition temperature of superconductors.
