1He-Ar isotope geochemistry of the Yaoling-Meiziwo tungsten deposit,North Guangdong Province:Constraints on Yanshanian crust-mantle interaction and metallogenesis in SE China显示文摘Isotopic abundances and ratios of He and Ar found in inclusion fluids in pyrites formed in the Yaoling-Meiziwo tungsten miner-alization epoch show that the concentration of 4He varies widely,from 1.54×10-7 cm3 STP/g to 2609×10-7 cm3 STP/g.3He is 0.759×10-12 cm3 STP/g-3.463×10-12 cm3 STP/g.3He/4He is 0.0043-4.362 Ra,varying from crustal to mantle values.The concen-tration of 40Ar ranges from 0.624×10-7 cm3 STP/g to 8.89×10-7 cm3 STP/g.The 40Ar/36Ar varies extensively,from 330 to 2952,between atmospheric and crustal or mantle radiogenic values.Mantle-derived He is present in ore-forming fluids and the calcu-lated average proportion of the mantle He is 22%;the maximum is 67%.Our research results show that mantle-derived fluids play a significant role in tungsten mineralization.The fractionation of He and Ar indicate that there was 4He-enriched air-saturated water(MSAW) in the ore-forming fluid.The ore-forming fluid was a mixture of mantle fluid,crustal magmatic fluid and MSAW.The occurrence of a mantle component in ore-forming fluid indicates the large-scale W and Sn mineralization,including Yaol-ing-Meiziwo,in southeastern China was the result of crust and mantle interaction.The underplating or intrusion of voluminous basaltic magma formed by partial melting of the upper mantle provided the necessary heat to cause partial melting of the crust and the generation of voluminous S-type granitic magmas.Crustal magmatic fluid and mantle fluid with high 3He/4He were released from magma crystallization and fractionation,mixed with the circulating modified air-saturated water,and filled the extensional tectonic fractures,leading to the formation of world-class W and Sn deposits in southeastern China.ZHAI Wei SUN XiaoMing WU YunShan SUN YanYan HUA RenMin YE XianRen 2012Chinese Science Bulletin2012,57,10:16
2Kinetics of Hydrogen Absorption in Hydrogen Storage Alloy显示文摘Hydrogenation kinetics of MLNi3.8(Co,Mn,Al)1.2 and MLNi3.7(Co,Mn,Al)1.2Cu0.1 alloy in α + β phase at the temperatUre range of 30 ~70 ℃ has been studied. The kinetic mechanism of hydrogen absorption is not affected by initial hydrogen pressure. Temperature does not influence the rate of hydrogen absorption obviously. In the prior and later period of hydrogen absorption the rate-controlling step is chemical reaction and hydrogen diffusion in the hydride phase respectively for MLNi3.8(Co,Mn,Al)1.2 alloy. Adding Cu, the rate-controlling step changes from chemical reaction to the nucleation and growth of β phase in the prior period and the process of hydrogen absorption still controlled by diffusion in the later period.LIN Qin CHEN Ning YE Wen LIU Renmin(Applied Science School, USTB, Beijing 100083, China) (General Research Institute of Non-Ferrous Metals Beijing, 100088) 1997International Journal of Minerals,Metallurgy and Materials1997,11,2:10
3中美中学生对由父母原因引起的考试焦虑认知研究显示文摘目的:比较中国和美国的中学生对由父母原因引起的考试焦虑的认知情况。方法:采用“失败结果预期(FOE)”问卷中的由父母原因引起的考试焦虑12项,测量中美两国公立学校14、15岁的1215名中学生对考试焦虑原因的认知。结果:1.相似认知:两国学生在由父母原因引起的考试焦虑方面有类似的认知,包括父母会担心自己能否进入高一级学校、会让父母烦恼等。2.跨文化的差异:表现为中国学生更多是因为父母责备、辜负了父母期望或会让父母生气而导致考试焦虑;而美国学生更多是由于父母认为他们不能面对生活中的挑战而产生焦虑。3.性别差异:表现在美国的女中学生在7个项目上、中国的男中学生在2个项目上分别比本国异性有更大程度的焦虑(P<0.05)。结论:中美中学生对由父母原因引起的考试焦虑方面有类似的认知,但存在文化差异和性别差异。邢利芳 黄辛隐 黄会欣 Kathryn Sanchez Renmin Ye 2005中国心理卫生杂志2005,19,8:7
4对考试后果的担忧:中国与美国中学生的比较研究显示文摘在调查和分析中国与美国14-15岁的中学生对重要考试的后果的担忧情况的基础上,比较了两国学生的担忧水平,考察了由于父母、教师、同学或自身的原因而导致的担忧,并分析了两个国家的学生在这些担忧上的性别差异。两国学生在父母原因方面的担忧程度均较高。对于中国学生,考试焦虑的第二个原因是教师;而对美国学生,第二焦虑原因来自自身。中国学生的性别与对重要考试的担忧没有明显联系;而在美国,女生比男生的担忧程度要高。黄辛隐 黄会欣 邢利芳 Kathryn Sanche Ye renmin 2005南通大学学报(教育科学版)2005,21,1:1
5Direct synthesis of high-quality perovskite nanocrystals on a flexible substrate and deterministic transfer显示文摘Solid-state perovskite nanocrystals are promising coherent light sources, as there is optical feedback within the crystal structure. In order to utilize the high performance of perovskites for on-chip applications, or observe new physical phenomena, these crystals must be integrated with pre-fabricated electronic or photonic structures. However, the material's fragility has made the deterministic transfer a great challenge thus far. Here, we report the first deterministic transfer of perovskite nanocrystals with sub-micron accuracy. Cesium lead halide(CsPbI_3) nanocrystals were directly synthesized on flexible polydimethylsiloxane(PDMS) stamps via chemical vapor deposition(CVD) and subsequently transferred onto arbitrary substrates/structures. We demonstrated the transfer of a CsPbI_3 crystalline nanoplate(NP)onto an 8 mm fiber core and achieved single-mode whispering gallery mode lasing. Our method can be extended to a variety of other arbitrary substrates(e.g., electrodes, photonic structures, micromechanical systems), laying the foundations for previously unattainable opportunities in perovskites-based devices.Yilun Wang Xing Cheng Kai Yuan Yi Wan Pan Li Yuhao Deng Haoran Yu Xiaolong Xu Yi Zeng Wanjin Xu Yanping Li Renmin Ma Kenji Watanabe Takashi Taniguchi Yu Ye Lun Dai 2018Science Bulletin2018,63,23:0
