1青藏高原东北缘冬给错纳湖全新世湖面波动显示文摘青藏高原处于东亚季风、印度季风和西风环流交互作用区.末次冰消期以来,太阳辐射对该地区的古气候环境产生了重要影响,湖泊随着季风系统的变化发生了明显的水位升降,对湖岸阶地的形成起到了直接作用.本项研究重建了青藏高原东北缘冬给错纳湖湖岸阶地记录的湖面波动历史,试图了解青藏高原季风系统演变过程.通过湖泊北岸265 cm厚湖岸阶地沉积物粒度、碳酸盐、矿物、元素和介形虫古环境指标,结合OSL年代模式,分析表明在约10. 2 ka B. P.之前水体较浅;约10. 2~9. 0 ka B. P.湖面开始上升,气候凉湿;9. 0~8. 5 ka B. P.为印度季风强盛期,湖面明显上升,降雨量增高、温度上升;8. 5~7. 9 ka B. P.湖面降低与气候变冷有关;7. 9~7. 0 ka B. P.印度季风开始减弱,气温、降雨下降,但有效湿度较大,湖面降低;7. 0~6. 1 ka B. P.湖面上升可能与低蒸发作用有关,印度季风仍然影响该地区;6. 1~5. 2 ka B. P.,印度季风衰退,气候逐渐变冷、降雨量减小、水体变浅;5. 2~4. 6 ka B. P.气候冷干,有效湿度减小,湖面进一步下降;4. 6 ka B. P.至今气候干冷,东亚季风衰退,湖面下降,期间也可能受西风环流影响而有短暂的降雨增加时期.张菀漪 张静雅 Nusrat Nazir Safarov Khomid 郑淇 Mischke Steffen 张成君 2019第四纪研究2019,39,4:9

3绿泥石新型抑制剂PSSNa在钛铁矿浮选中的作用机理研究显示文摘为了解决钛铁矿浮选中绿泥石等具有一定天然疏水性的脉石矿物易混入精矿中,降低精矿品质的问题,研究了新型绿泥石抑制剂聚苯乙烯磺酸钠(PSSNa)的抑制效果和作用机理。微浮选试验结果表明:PSSNa能够选择性抑制绿泥石的浮选,在最优条件下钛铁矿回收率高于绿泥石近50个百分点,为浮选分离创造了良好条件。接触角测试结果显示,聚苯乙烯磺酸钠可大幅降低油酸钠对绿泥石表面的疏水化作用,而对油酸钠疏水化钛铁矿的能力影响不大;红外光谱检测结果表明,相比于钛铁矿,PSSNa通过其磺基与绿泥石表面的镁原子发生化学吸附作用,表现出选择性;吸附量测量结果显示,该吸附了聚苯乙烯磺酸钠分子阻止了油酸钠在绿泥石表面的进一步吸附。分子动力学模拟结果,从分子水平解释了该抑制剂对钛铁矿和绿泥石的选择性吸附、抑制作用。杨慧 王振 Safarov S 邹旦 许颖 2022现代矿业2022,38,7:2

12新型组合捕收剂强化毒砂浮选机理研究显示文摘青海某金矿的主要载金矿物为毒砂,现场采用酸性条件下的异戊黄药捕收体系进行富集,存在酸耗大、设备腐蚀、硫化矿溶解等问题,为此对弱碱性条件下正十二烷基硫醇与异戊黄药组合使用强化毒砂捕收的机理及初步应用进行了研究。毒砂纯矿物浮选试验结果表明,异戊黄药对毒砂的捕收能力略优于正十二烷基硫醇,在异戊黄药体系中加入适量正十二烷基硫醇可以在总捕收剂用量较低的情况下,获得较高的毒砂回收率。接触角测试结果显示,正十二烷基硫醇和异戊黄药均能使毒砂矿物表面的疏水性提高,浓度分别为5×10^(-5)、1×10^(-4) mol/L的正十二烷基硫醇和异戊黄药组合使用可使毒砂矿物表面的接触角(69.18°)高于单独使用浓度为2×10^(-4) mol/L的异戊黄药的毒砂矿物表面的接触角(64.36°)。红外光谱检测结果表明,正十二烷基硫醇和异戊黄药均在毒砂矿物表面发生了化学吸附,二者组合使用时这种吸附作用更强,捕收剂吸附量更大。针对原矿金品位为4.48 g/t的某金矿石,基于该组合捕收剂的药剂体系,可以在pH为9的弱碱性条件下以较低的总捕收剂用量获得金回收率为92.44%的选别效果,优于酸性条件下单独使用异戊黄药的捕收效果。杨慧 王振 Safarov Sayfidin 赵开乐 2022化工矿物与加工2022,51,7:1

19Induced radioactivity at particle accelerators:a short review显示文摘Purpose The induced radioactivity in accelerator components and decay characteristics of radioactive nuclei contained therein is critical for radiation safety of occupational workers as well as for the maintenance,repair,and decommissioning activities.The topic of induced radioactivity is widely reported and extensively explored in the literature by many researchers up to now.This mini-review would demonstrate the current state of the knowledge on induced radioactivity at particle accelerators.Methods In this article,the concepts of activation-related studies and radionuclide generation in accelerator environments are reviewed.In addition,some studies on accelerator-induced radioactivity by Monte Carlo and experimental measurement methods are briefly described.Results and conclusions The possible radiation protection problems caused by particle accelerator-induced radioactivity are briefly reviewed and analyzed.The produced radionuclides depend on the beam parameters such as particle type,energy,irradiation period,cooling time,and irradiated material.The Monte Carlo simulation method offers comparable advantages over empirical analysis method.A review of major studies in the field of induced radioactivity of particle accelerators confirmed that the extremely strong induced radioactivity generated at hot spots of accelerators means new challenges to radiation safety and deserves further investigation and discussion.Shakhboz Khasanov Bo Yang Youwu Su Akmal Safarov Yao Yang 2021Radiation Detection Technology and Methods2021,5,4:0
