摘　　要：为提高含铀微粒中铀同位素比值的测定水平,欧盟联合研究中心"标准物质和测量研究所"定期组织微粒分析技术的国际比对。中国原子能科学研究院微粒分析实验室于2010年参加了"核特征的实验室间测量评价计划"(NUSIMEP-7),旨在准确测量含铀微粒中同位素比值。本研究测量了单同位素、双同位素沉积碳片上含铀微粒的235 U/238 U、234 U/238 U、236 U/238 U,结果表明,90%以上的测量数据在"满意数值"范围内。In order to improve the measuring capability of analysis of uranium isotope ratios of particles,the international comparison of particle analysis has been held regularly by Institute for Reference Materials and Measurements of Joint Research Centre of European Commision.In 2010,the laboratory of particle analysis in China Institute of Atomic Energy participated the comparison aiming ＂uranium isotope amount ratios in uranium particles＂which subjects to Nuclear Signatures Interlaboratory Measurement Evaluation Programme（NUSIMEP-7）.235 U/238 U,234 U/238 U and 236 U/238 U of particles including the single and double isotopic depositions of uranium in carbon planchets was measured.The results show more than 90% datum are within the satisfactory results,that confirm our capability of particle analysis.
