| 1 | Geochemical processes and origin of boron isotopes in geothermal water in the Yunnan-Tibet geothermal zone显示文摘Boron concentrations and isotope compositions have been measured for 93 water samples from the hot springs and drill-holes in the geothermal system in the Yunnan-Tibet Geothermal Belt(YTGB),China.Boron concentrations range from 0.036–472.4ppm,and theδ11B values range from -16.0‰to 13.1‰,indicating the non-marine origin for each geothermal system.We observed a clear binary mixing relationship between the B concentrations and B isotope compositions in Tibet geothermal area.This relationship can be well explained by two sources,i.e.,marine carbonate rocks and magmatic rocks,for the Tibet geothermal water.No evidence supports a mantle contribution to B.In addition,we found that the precipitation only plays a dilution role for B of geothermal waters.δ11B values for the precipitation across the southern Tibetan Plateau area range from -6.0‰ to -6.8‰at least.Due to data scarcity in Yunnan geothermal area,we observed possible different boron sources from the Tibet geothermal system.Comparing it with other geothermal systems in the world,we found that the samples from YTGB have the lowestδ11B values and the largest range of B concentration,which might be related to their special geological background.On the whole,the world geothermalδ11B-Cl/B relation suggests a mixing process between marine and non-marine sources.Additionally,we suggest that B source of B-enriched geothermal waters is mainly from B-enriched crustal country-rocks,instead of mantle. | Lü YuanYuan ZHENG MianPing ZHAO Ping XU RongHua | 2014 | Science China Earth Sciences2014，57，12： | 6 |
| 2 | Geomorphometric Features of the Alluvial Fans around the Chaka-Qinghai Lake in the Northeastern Tibetan Plateau显示文摘This article aims to study the geomorpometric features of alluvial fans since they act as a small-scale geomorphic unit response to tectonics and climate changes around the Chaka-Qinghai Lake area in the northeastern Tibetan Plateau.We quantitatively extracted geomorphic parameters,such as the surface area and slope of alluvial fans adjacent to the Qinghai Nan Shan and Ela Shan.Alluvial fans in the Chaka Lake partition area,south of the Qinghai Nan Shan,are featured by a small area and short length,but the largest slope.Geomorphic parameters of the alluvial fans in Ela Shan area are intermediate in size,and the alluvial fans in the Qinghai Lake partition area north of Qinghai Nan Shan have the gentlest slope.Together with the regional faulting activity analysis,we suggest that the alluvial fans with the high slopes in the south of Qinghai Nan Shan are mainly controlled by the reverse faulting along the Qinghai Nan Shan faults,and the strike-slip movement of the Ela Shan fault zone plays a weak role.In contrast,due to the lack of active faults,the alluvial fans near the Qinghai Lake area north of the Qinghai Nan Shan only respond to regional erosion,transportation,and deposition processes,thereby forming relatively gentle geomorphic units. | Huiping Zhang Yuanyuan Lü | 2014 | Journal of Earth Science2014，25，1： | 2 |
| 3 | Characteristics of urban boundary layer in heavy haze process based on Beijing 325m tower data显示文摘2015年11月24日至2015年12月2日北京市经历了一次严重的雾霾污染过程。本文利用这次过程期间北京325米气象塔的观测资料,对重污染天气条件下的边界层风场、温度场、湿度场和湍流特征进行了分析研究。本次污染过程并未发布红色预警,但是实际的污染形势被低估了,本文也对低估原因进行了分析。结果表明:北京地区这次污染过程主要是由偏东风和偏南风引起的,11月29日高层(280米)风速增加而低层(15m)风速并未增加,且次日高层风速大幅减小,导致了对于这次污染形势的低估。风速、湍动动能和摩擦速度与PM2.5浓度呈反相关关系。在晴天,风速随高度的增加而显著增加,但在污染严重的时期,风速从近地层到塔顶的变化不是很大。湍流动能从近地层到铁塔高层的变化并不是很明显。雾霾过程通常伴随有逆温层的出现,边界层内温度的日变化很小。在严重污染时,相对湿度接近100%,此时感热通量和水汽通量也都减小,湍流活动受到抑制,湍流活动强度的减弱又会进一步加重污染形势。 | SHI Yu HU Fei Lü Rui HE Yuanyuan | 2019 | Atmospheric and Oceanic Science Letters2019，12，1： | 2 |
| 4 | Arg462Gln and Asp541Glu polymorphisms in ribonuclease L and prostate cancer risk:a meta-analysis显示文摘Objective:The association between ribonuclease L(RNASEL)gene polymorphisms and prostate cancer risk has been widely reported,but the results of these studies remained controversial and underpowered.We performed a meta-analysis of 28 studies to evaluate the association between Arg462Gln and Asp541Glu polymorphisms in the RNASEL gene and prostate cancer risk.Methods:Odds ratios(ORs)with 95%confidence intervals(CIs) were estimated to assess the association between RNASEL polymorphisms and prostate cancer risk.Results:A significantly increased prostate cancer risk was found for the Arg462Gln polymorphism in Africans(Gln/Gln vs Arg/Arg:OR=2.50,95%CI=1.28-4.87;Gln/Gln vs Gln/Arg+Arg/Arg:OR=2.54,95%CI=1.30-4.95),but not in Europeans and Asians.Additionally,the Asp541Glu polymorphism was associated with increased total prostate cancer risk(Glu-allele vs Asp-allele:OR=1.04,95%CI=1.01-1.07;Glu/Glu vs Asp/Asp:OR=1.22,95%CI= 1.03-1.46;Glu/Glu vs Glu/Asp+Asp/Asp:OR=1.09,95%CI=1.02-1.16).In the stratified analysis for the Asp541Glu polymorphism,there was a significantly increased prostate cancer risk in Africans and Europeans,and in hospital-based prostate cancer cases.Conclusion:The meta-analysis results showed evidence that RNASEL Arg462Gln and Asp541Glu polymorphisms are associated with prostate cancer risk and could be low-penetrance prostate cancer susceptibility biomarkers. | Yuanyuan Mi Qianqian Yu Zhichao Min Bin Xu Lifeng Zhang Wei Zhang Ninghan Feng L ixin Hua | 2010 | The Journal of Biomedical Research2010，24，5： | 2 |
| 5 | 诸葛亮治蜀与蜀汉的国家建构显示文摘自东汉中期以降,政治衰败迅速加剧,原本王朝国家的政治权威在经历黄巾起义和董卓乱政的打击后不复存在,政治秩序土崩瓦解,帝国陷入军阀割据、群雄逐鹿的状态。政治权力的破碎化使得国家建构成为每个统治者/执政在追求统一时必须面对的难题。在各大势力相互竞争的过程中,曹操、刘备、孙权三家脱颖而出并最终形成了魏、蜀、吴三足鼎立的趋势。其中,诸葛亮治下的蜀汉政权改革了东汉中期以来形成的政治流弊,不仅建立了“宫府一体”制度,形成了有效的政治整合,在一定程度上实现了士人政治的追求,而且增强了国家力量,塑造了中国古代王朝国家治理的理想类型,为后世所称颂。 | 杨端程 Liu Yongtao Zhang Wanlin Lü Yuanyuan | 2021 | 天府新论2021，，5： | 2 |
