硫化氢吸收液的电化学分解条件研究

理想的脱硫工艺应满足体积小、费用低、净化度高、无二次污染等要求。在碱性溶液吸收微量硫化氢时同步进行电解，可有效减小设备体积，并将硫化氢转变为氢气和硫磺，不产生恶性气味。为此，实验研究了温度、浓度、电流密度、pH值等因素对电解阳极过程的影响，确定了适宜的电解条件，并在该条件下进行了吸收实验。结果表明，在最佳电解条件下，硫化钠溶液能充分吸收天然气中经变压吸附提浓的硫化氢（800 mg/m³），吸收率大于99.9％。

Laboratory study of property-modified prebaked carbon anode and application in large aluminum electrolysis cells

A kind of complex additive mainly containing Al, Mg, F, and O was prepared. The synthetical performances of the property-modified prebaked anodes containing additives were tested in laboratory. On the basis of ideal testing results obtained, a large number of industrial prebaked property-modified anodes are prepared in a large-scale aluminum company. Further more, they are all used in 160 kA prebaked anode aluminum electrolysis cells. The statistic result show that, compared with common anodes, the property-modified ones enhance current by 11.6 kg per ton aluminum averagely.     

Visual thinking in arts education: Homage to Rudolf Arnheim.

The influence of Arnheim's work on the author's research began with an experiment on the perception of visual balance. Two later research projects emerged from the profound influence of Arnheim's stance toward creation in the visual arts as a serious, cognitive endeavor. A series of meta-analyses were first conducted to test the claim that learning in the arts transfers to nonarts cognitive domains, but little evidence was found. Past research on the transfer hypothesis was found to be lacking because of its failure to assess learning in the parent domain. Therefore, a new research project was carried out to identify kinds of learning in the parent domain of visual arts. We identified eight thinking dispositions developed in serious visual arts classes, setting the stage for more plausible transfer studies. This study demonstrates that the visual arts inculcate basic skills in perception and cognition that exist both in the arts and sciences. All of the skills the authors describe can, with some modification, be transferred to the science laboratory. As Rudolf Arnheim has taught us, visual thinking is everywhere.

薄板坯连铸连轧工艺对铌微合金化高强度钢组织和性能的影响

首先建立薄板坯连铸连轧工艺的试验室模拟技术，并运用该模拟技术，研究薄板坯连铸连轧工艺(CSP)和传统板坯再加热工艺(TRP)两种工艺对铌微合金化高强度钢的显微组织和力学性能的影响。研究结果表明：CSP钢的晶粒细化效果不如TRP钢，两者的平均铁素体晶粒尺寸分别为8．17μm和6．30μm。在CSP试验钢板中铌的析出量较大，特别是在铁素体中细小颗粒的铌的析出物较多，沉淀强化效果较强。CSP试验钢的σ0.5和σb分别较TRP工艺低约40MPa和约25MPa，同时其低温冲击韧性较好，FATT温度较低。     

The High Field Project at Dresden/Rossendorf: A Pulsed 100 T/10 ms Laboratory at an Infrared Free-Electron-Laser Facility

This article describes the project to build a pulsed magnetic field user laboratory at the Forschungszentrum Rossendorf near Dresden. Using a 50 MJ/24 kV capacitor bank, pulsed fields and rise times of 100 T/10 ms, 70 T/100 ms, and 60 T/1 s should be achieved. The laboratory will be built next to a free-electron-laser-facility for the middle and far infrared (5 to 150 µm, 2 ps, cw). We describe the work which has been performed until now to start the construction of the laboratory in 2003: coil concepts and computer simulations, materials development for the high field coils, and design of the capacitor bank modules. In addition, a pilot laboratory has been set up where fields up to 62 T/15 ms have been obtained with a 1 MJ/10 kV capacitor module. It is used to gain experience in the operation of such a facility and to test various parts of it. In this test laboratory special devices have been developed for measurements of magnetization and magnetoresistance, and have been successfully used to investigate various materials including semiconductors and Heavy Fermion compounds. In particular, metamagnetic transitions in intermetallic compounds and the irreversibility field of a high-T _c superconductor have been determined. Shubnikov–de Haas oscillations have been observed in the semimetallic compound CeBiPt. Resistance relaxation has been observed to start less than 1second after the field pulse. It could be shown for the first time that nuclear magnetic resonance (NMR) is detectable in pulsed fields.

焦化防砂室内实验研究

油井防砂工艺技术的研究与发展对疏松砂岩油藏的正常开采至关重要.焦化防砂是通过向地层内注入热空气使原油在高温下发生氧化裂解生成焦炭从而将地层砂固结的一种防砂新技术.为了对该项技术进行全面系统的理论分析与评价,设计并制作了一套焦化防砂实验装置,利用该装置进行了焦化防砂室内实验研究.焦化效果以岩样的抗压强度进行评价,实验结果表明,影响焦化后岩样抗压强度的主要因素为空气最高温度、处理时间和空气流量.此外,对焦化处理后的岩样所作的岩样组成分析揭示出,稠油胶结机理为氧化作用使部分油分和胶质变成沥青质,沥青质受到高度的缩合作用而成为高分子量的甲苯不溶物.由于新生胶质的氧化比原生胶质的氧化困难得多,因此适合焦化防砂的油层,其原油必须含有一定量的原生胶质和沥青质.
