摘要：
Calculations were performed on a model of multi-component, fine-grained materials to simulate positron distributions immediately after the thermalization process. A real three-component system (beta-Ni(OH)2/beta-NiOOH/graphite) was fitted by the parameters of the model and positron lifetime parameters were determined for the interfaces of the system.
