1用TBP和TOPO从酸性溶液中萃取钼(Ⅵ)显示文摘研究了用磷酸三丁酯(TBP)和三辛基氧磷(TOPO)从盐酸、硝酸和硫酸溶液中萃取钼(Ⅵ)。根据取得的萃取分配数据,提出了平衡表达式。用TBP从盐酸和硝酸溶液中萃取钼(Ⅵ)的平衡式,在低酸度下为:T.Sato 吕林 1991湿法冶金1991,10,1:3
2用酸性有机磷化合物从酸性水溶液中液-液萃取铟(Ⅲ)显示文摘本文研究了在不同的条件下,铟(Ⅲ)在硫酸、硝酸或盐酸水溶液与二-(2-乙基己基)-磷酸(DEHPA)或2-乙基己基膦酸2-乙基己基酯(EHEHPA)煤油溶液之间的分配。对有机萃合物进行了红外光谱和核磁共振分析。结果发现,DEHPA对铟(Ⅲ)的萃取率高于EHEHPA;而且发现,酸性水溶液的种类对铟(Ⅲ)萃取的影响在低酸度下依次为:HNO_3>H_2SO_4>HCl,而在较高酸度下顺序则相反。萃取实验表明,DEHPA从硫酸或硝酸溶液中萃取的分配系数随着水溶液酸度的增加呈单调下降;从盐酸溶液中萃取的分配系数,在酸度低于1mol dm^(-3)时随着酸度的增加呈单调下降,而在酸度高于1mol dm^(-3)直至5mol dm^(-3)时则随酸度而增大,然后在更高酸度时又下降。EHEHPA的萃取曲线与DEHPA的相似,只是它从盐酸溶液中萃取的分配系数在水溶液酸度高于1mol dm^(-3)时有轻微的下降。最后依据所得结果提出了相应的平衡方程式。T.Sato 蒋志美 1993湿法冶金1993,12,1:3
3Stabilization of a high-order harmonic generation seeded extreme ultraviolet free electron laser by time-synchronization control with electro-optic sampling显示文摘A fully coherent free electron laser(FEL) seeded with a higher-order harmonic(HH) pulse from high-order harmonic generation(HHG) is successfully operated for a sufficiently prolonged time in pilot user experiments by using a timing drift feedback. For HHG-seeded FELs, the seeding laser pulses have to be synchronized with electron bunches. Despite seeded FELs being non-chaotic light sources in principle, external laser-seeded FELs are often unstable in practice because of a timing jitter and a drift between the seeding laser pulses and the accelerated electron bunches. Accordingly,we constructed a relative arrival-timing monitor based on non-invasive electro-optic sampling(EOS). The EOS monitor made uninterrupted shot-to-shot monitoring possible even during the seeded FEL operation. The EOS system was then used for arrival-timing feedback with an adjustability of 100 fs for continual operation of the HHG-seeded FEL. Using the EOS-based beam drift controlling system, the HHG-seeded FEL was operated over half a day with an effective hit rate of 20%–30%. The output pulse energy was 20 μJ at the 61.2 nm wavelength. Towards seeded FELs in the water window region, we investigated our upgrade plan to seed high-power FELs with HH photon energy of 30–100 e V and lase at shorter wavelengths of up to 2 nm through high-gain harmonic generation(HGHG) at the energy-upgraded SPring-8Compact SASE Source(SCSS) accelerator. We studied a benefit as well as the feasibility of the next HHG-seeded FEL machine with single-stage HGHG with tunability of a lasing wavelength.H.Tomizawa T.Sato K.Ogawa K.Togawa T.Tanaka T.Hara M.Yabashi H.Tanaka T.Ishikawa T.Togashi S.Matsubara Y.Okayasu T.Watanabe E.J.Takahashi K.Midorikawa M.Aoyama K.Yamakawa S.Owada A.Iwasaki K.Yamanouchi 2015High Power Laser Science and Engineering2015,3,2:1

7Negative Parity States in ^(39)Cl Configured by Crossing Major Shell Orbits显示文摘Traditional 'magic numbers' were once regarded as immutable throughout the nuclear chart. However, unexpected changes were found for unstable nuclei around N = 20. With both proton and neutron numbers around the magic number of 20, the neutron-rich ^(39)Cl isotope provides a good test case for the study of the quantumstate evolution across the major shell. In the present work, the negative parity states in ^(39)Cl are investigated through the β decay spectroscopy of 39 S. Newly observed γ transitions together with a new state are assigned into the level scheme of ^(39)Cl. The spin parity of 5/2^- for the lowest negative parity state in ^(39)Cl is reconfirmed using the combined γ transition information. These systematic observations of the negative parity states in ^(39)Cl allow a comprehensive comparison with the theoretical descriptions. The lowest 5/2^- state in ^(39)Cl remains exotic in terms of comparisons with existing theoretical calculations and with the neighboring isotopes having similar single-particle configurations. Further experimental and theoretical investigations are suggested.陶龙春 Y.Ichikawa 袁岑溪 Y.Ishibashi A.Takamine A.Gladkov T.Fujita K.Asahi T.Egami C.Funayama K.Imamura 楼建玲 T.Kawaguchi S.Kojima T.Nishizaka T.Sato D.Tominaga 杨晓菲 H.Yamazaki 叶沿林 H.Ueno 2019Chinese Physics Letters2019,36,6:1

14用酸性有机磷化合物从酸性水溶液中萃取稀土元素显示文摘本文研究了在不同的条件下,三价稀土元素:(?)、铈、镨、钕、钐、铕、钆、铽、镝、钬、铒、铥、镱和镥在盐酸水溶液和DEHPA或EHEHPA煤油溶液之间的分布。对有机萃合物进行了红外光谱和核磁共振的分析。DEHPA和EHEHPA萃取这些元素的萃取效率顺序为(?)<铈<镨<钕<钐<铕<钆<铽<镝<钬<铒<铥<镥,这个值随元素的原子序数的增加而增加,尽管前者的离子半径比后者大。另外,以每四个稀土元素为一组,绘制了DEHPA和EHEHPA萃取稀土元素的分配系数与元素原子序数的函数关系曲线。在从硝酸溶液中萃取时,也观察到了类似的现象。结果表明,在低酸度的水溶液中,DEHPA和EHEHPA萃取稀土元素按阳离子交换反应进行;在高酸度的水溶液中,则发生了某种程度的溶剂化反应。T.Sato 曹淑清 1990湿法冶金1990,9,1:0
15用二(2-乙基己基)磷酸从盐酸溶液中萃取锡(Ⅳ)显示文摘研究了不同条件下锡在盐酸水溶液和二(2-乙基己基)磷酸(DEHPA,HX)煤油溶液间的分配。用分光光度、红外光谱法和核磁共振光谱法测定了有机萃合物。结果发现,在低酸度下锡的萃取取决于离子交换反应:SnCl_2(aq)^(2+)+(HX)_2(org)(?)SnCl_2X_2(org)+2H_(aq)^+而在较高酸度下则取决于溶剂化反应:SnCl_4(aq)+(HX)_2(org)(?)SnCl_42HX(org)T.Sato 鞠永善 1990湿法冶金1990,9,1:0
16与1989年伊豆半岛近海地震和火山活动有关的水文和地球化学变化显示文摘我们对伊豆市一个温泉的水位、中伊豆的温泉水氡浓度以及伊豆-大岛火山喷发气体的温度变化进行了监测。在伊豆半岛东面近海1989年6月30日地震和火山活动之前和活动时期,这些观测数据都发生了变化。本文将这些观测结果和其他报道的水文变化一起加以概述。这些变化可以分成两种类型:一种是在震群当中最大地震发生时的震时变化,这种变化是在离Teisi喷发中心20—30km的几个温泉中观测到的。另一种是在靠近喷发中心地区和离伊豆-大岛火山40 km处观测的前兆变化。由于岩浆可能呈一种岩墙状的侵入,它的上涌便会对伊豆市和宇佐美镇的水文系统产生强烈地扰动。由伊豆-大岛火山的一个钻孔中喷气温度的前兆变化意味着伊豆-大岛和Teisi岩浆系统可能是有联系的。K.Notsu H.Wakita G.Igarashi T.Sato 唐仲兴 1995世界地震译丛1995,26,3:0

18Van Hove Singularities as a Result of Quantum Confinement:The Origin of Intriguing Physical Properties in Pb Thin Films显示文摘In situ angle-resolved photoemission spectroscopy(ARPES)and scanning tunneling spectroscopy(STS)have been used to study the electronic structure of Pb thin films grown on a Si(111)substrates.The experiments reveal that the electronic structure near the Fermi energy is dominated by a set of m-shaped subbands because of strong quantum confinement in the films,and the tops of the m-shaped subbands form an intriguing ring-like Van Hove singularity.Combined with theoretical calculations,we show that it is the Van Hove singularity that leads to an extremely high density of states near the Fermi energy and the recently reported strong oscillations(with a period of two monolayers)in various properties of Pb films.Yu Jie Sun S.Souma Wen Juan Li T.Sato Xie Gang Zhu Guang Wang Xi Chen Xu Cun Ma Qi Kun Xue Jin Feng Jia T.Takahashi T.Sakurai 2010Nano Research2010,3,11:0
