Characterization of (Y,Gd) BxV1-xO4-x:Eu Phosphor Prepared by Coprecipitation Reaction

White body-color (Y, Gd)BxV1- xO4-x :Eu3 phosphors were prepared by coprecipitation reaction. Under VUV excitation at 147 nm, the red emission colorimetric purity of (Y, Gd)BxV1- xO4-x :Eu3 phosphor is much better than that of commercial PDP (plasma display panels) phosphor (Y, Gd)BO3:Eu3 . But its relative emission intensity is only about 90% of the commercial phosphor.

田湾核电站2004年(运行前)的环境监测

田湾核电站环境监测系统于2003年底前建成,为了检验田湾核电站环境监测的仪器设备、规程文件、质控措施和人员的技术水平是否满足运行时的要求,扩大和改善运行前的环境本底数据,并通过实践的经验反馈发现存在的问题,提出改进方案和措施,田湾核电站在2004年对核电站周围进行了（运行前）的环境监测.本文主要介绍2004年环境监测的方案、质量保证和主要监测结果及其与2000年4月～2002年3月二年的本底调查结果的比较.2004年监测结果表明,除海水中137Cs活度浓度与本底调查有明显差异外,其余监测结果与本底调查结果基本吻合.     

急性放射损伤小鼠血清蛋白质组分析

为寻找急性放射病早期诊断指标和新的治疗靶点，探讨辐射损伤的发病机理，采用蛋白质组学的双向电泳和蛋白质氨基酸序列分析技术研究了8Gy γ射线照射后24h小鼠血清蛋白质的变化，鉴定有差异的蛋白质，并用蛋白质印迹(Western blotting)方法进行验证。结果显示，双向电泳发现8Gy照射后24h小鼠血清有一显著变化蛋白点，分子量约为15ku，经氨基酸序列分析发现为结合珠蛋白(Haptoglobin，Hp)的α亚单位。Western blotting方法进一步验证了双向电泳的结果。结果表明，经8Gy γ射线照射后24h小鼠血清中结合珠蛋白发生显著增加，可能在辐射损伤中发挥着一定的作用，此结果为探索急性放射损伤的发病机理提供了新的线索。     

Strain Measurement on the Toroidal Field （TF） Coil Cases

The stress-strain state of the structure is a matter of interest to designer. The strain measurement of superconducting magnets at cryogenic temperature is a specific technique. Based on strain measurement of TF coil case for EAST, this paper presents a measuring technique at cryogenic temperature and on intense magnetic field. The compensation methods for both temperature and magnetic field effects of the gauges, together with the measured results are involved, and the discussions of the measured results are given in the paper.     

Electron impact collision strengths and oscillator strengths for Ni-like Nd, Sm, Eu, Gd, Ta, and W ions

Energy levels, oscillator strengths, and electron impact collision strengths have been calculated for Ni-like ions of Nd (Z = 60), Sm (Z = 62), Eu (Z = 63), Gd (Z = 64), Ta (Z = 73), and W (Z = 74) among the 249 levels belonging to the ([Ne])3s²3p⁶3d¹⁰, 3s²3p⁶3d⁹nl, 3s²3p⁵3d¹⁰nl, 3s3p⁶3d¹⁰nl (n = 4, 5; l = 0, 1, … , n − 1) configurations. Configuration interactions among these configurations have been included in the calculations. Collision strengths have been obtained at 20 scattered electron energies (5–20,000 eV) and they have been listed at six representative energies of 100, 400, 1000, 2500, 5000, and 10,000 eV in this work. Effective collision strengths have been obtained by assuming a Maxwellian electron velocity distribution at 24 temperatures ranging from 100 to 3000 eV. Our results are compared with those available in the literature. The relative difference is within 0.3% between our calculated energy levels and the corresponding experimental values wherever available. The energy levels are expected to be be accurate within 0.6%, while oscillator strengths and collision strengths for strong transitions are probably accurate to better than 20%.
