摘　　要：吉布斯佯谬在许多教材中都归咎于没有考虑到量子力学中微观粒子的全同性,但是考虑了微观粒子的全同性的量子理想气体混合时,还会出现更多的佯谬,如内能的佯谬等其他佯谬。显然,引起佯谬的根本原因不是没有考虑粒子的全同性。因此,有必要进一步澄清吉布斯佯谬产生的缘由,并说明实际吉布斯佯谬是由粒子数密度突变造成的。Many textbooks ascribe the Gibbs paradox to the failure to account for the identity of microscopic particles in quantum mechanics.However,considering the identify of microscopic particles when quantum ideal gas mixing,there will be more paradox,such as the internal energy of paradox and other paradox.Obviously,the fundamental cause of paradox is not the absence of considering the particle's identity.Therefore,it is necessary to further clarify the reasons of the Gibbs paradox.Actually,Gibbs paradox is caused by mutation particle number density.
