The results indicated that (1) the 147Pm, 141Ce and 147Nd had strong adsorptivity in soil, so they were hard to transfer and easily accumulated in soil or sediment;(2) all the organisms (5 aquaties and 4 eatable plants) tested showed apparent 147Pm concentrating capabilities;(3)the residues of 147Pm, 141Ce and 147Nd were unevenly distributed in the animal's viscera and tissues, higher residues were found in bone, marrow, eye, brain, heart, adipose and testis, showing selective accumulation;(4) with intraperitioneal dosing of Nd or Ce 200mg ·kg -1 apparent inhibition to gonadial hormone secretion in mice was found and with 200 and 800mg·-1 of Ce added in feed, the malformation rate of spematozoon showed higher.

These concrete worksare the following:1, a new heterogonous SHS model had been proposed, which first included all the relativematerials characters, such as reactants particle sizes, changeable heat-conductivity and massdiffusion during SHS and so on, and its chemical reaction characters, initial combustion status.This new model made a more precise prediction about the SHS combustion way and itsTechnological characters possible.2, with the heterogonous SHS model, lots of combustion way had been imitated by changesystems relative factors and the rule of the combustion way change had also been studied,chemical reaction in these systems was controlled by a single mechanism.

在该模型中，首次将体系的微观不均匀特性、体系的基本物性及燃烧过程中的化学反应机理与整体燃烧动力学行为联系在一起，从而为更加准确地预测和控制SHS体系的燃烧行为，优化SHS的工艺过程奠定了理论基础。2、采用非均质燃烧模型，通过对相关参数的改变，模拟SHS燃烧过程中的各种燃烧行为，并研究了燃烧行为变化的规律。
