摘　　要：采用Stacey等人的热压-温度方程,考虑了内地核物质的热压值,结合对分子力大小的分析,利用量子统计物理的费米-迪拉克方程,计算了内地核物质可能的量子效应,并给出了与量子效应有关的各项参数.通过计算得知,巨大的地球自引力压强仅破坏了Fe原子的最外层和极少一部分次外层的电子结构,而没有像白矮星那样使物质所有的核外电子发生公有化.In this paper, the thermal pressure of the inner earth＇s core as studied on the basis of the Stacy EOS （equation of state）which is consistent with the thermodynamics of high pressure limit and completely compatible with the data derived from seismology. Having estimated the effect of pressure provided by the molecular force of Fe atoms,we calculated the matter＇s quantum effect of the earth＇s inner core with the Feimin-Dirac equation and presented all the parameters of the quantum effect in table 1. From this paper, we draw a conclusion that the huge earth gravitation only destroyed the outmost and a few second-outmost electrons energy levels of the Fe atom, rather than destroyed all energy levels like what has been done in the white dwarf.
