揭示了在地球核心内建立一个子结构的基本原理，该结构由位于地球中心的鳗系元素亚核组成，周围环绕着由核裂变和放射性衰变产物组成的亚壳。对可能的密度、物理尺寸和化学成分进行了估计。论证了亚核内自持核裂变的可行性，并讨论了对内核结构和地球动力学活动的影响。
The rationale is disclosed for a substructure within the Earth's inner core, consisting of an actinide subcore at the center of the Earth, surrounded by a subshell composed of the products of nuclear fission and radioactive decay. Estimates are made as to possible densities, physical dimensions, and chemical compositions. The feasibility for self-sustaining nuclear fission within the subcore is demonstrated, and implications bearing on the structure and geodynamic activity of the inner core are discussed.
