摘　　要：讨论了经γ射线作用后聚醚聚氨酯(ETPU)泡沫塑料的辐射老化规律。采用气相色谱、差热分析和电子自旋共振技术,研究了ETPU材料辐照后辐解气体产物的种类和生成量以及材料的热性能和自由基强度的变化。The radiation effect of γ-ray on polyether-urethane foam was studied. The gas products from irradiated samples were analyzed quantitatively and qualitatively by gas chromatography, the thermal property and radical intensity were determined by differential thermal gravimetric analysis and electron spin resonance.
