【摘要】 首先依据地球内部温度和密度不均匀分布数据，用计算机计算它的电离状态，得到非等温分层电离状态的电荷分布曲线；其次从地球内部存在的流体压力与两类体积力：重力和静电力的平衡方程讨论中，发现在某一等温层内可能存在微重力构造圈，其厚度约为１０００ｋｍ左右；最后在地学研究向整体化和深部化发展趋势下，预期这个结果将有助于理解地球深部发生的各种物理过程且与地震Ｓ波在核－幔之间层中消失观测事实相一致．更多还原

【Abstract】 At first,the curve of charge distribution,ionizable state of nonisothermatity sphere,Was obtained by computer to calculate ionized state according to distribution data of temperature and dinsity within Earth. Secondly,the pussibility of microgravitational testonosphere,Within the isothermality sphere,was found by balance between pressure and volumetric force(static charge and gravity)in Earth’s interior.The thickness is 1 000 km or so.Finally,the result come into commom use various geophysical process within deep Earth,and the theoritical result is in accord with observations of seismic S-wave disappeared between outer core and lawer mantle.更多还原
