摘　　要：应用低温(77K)ESR测定了一些有机磷化合物在低温(77K)γ辐照所产生的自由基,并以质谱及原子部分电荷计算结果,讨论了磷酸酯及膦酸酯的键结构与辐射稳定性的关系。The radiation stability of various chemical bonds of organic phospha-tes and phosphonates were studied by using of low-temperature (77K) ESR measure-ment of radicals formed in gamma-irradiated samples at 77 K, and by using of MSspectral analysis and the partial charges of atoms calculated by iterative partial equli-zation of orbital electronegativity.
