OSL 标明日期结果显示大湖以前形成了 ∼60 —50 ka,和在在 1060 和 1035 m a.s.l 之间的举起的四条海岸线多半从 ∼60 ∼50 ka 代表湖水平变化到早 Holocene。Megalake Jilantai-Hetao 的发现将多半影响黄河的发展的理解在期间晚第四级, Ulan Buh 和 Kubq 的进化抛弃,在这个区域的 neotectonism,并且可能地区性的气候的变化。CHEN FaHu FAN YuXin CHUN Xi D.B.

5INVESTIGATION OF SURFACE MORPHOLOGY, STRUCTURE AND ELECTROCATALYTIC PROPERTIES FOR O_2 EVOLUTION OF TITANIUM BASED IrO_2+Ta_2O_5 COATINGS显示文摘Titanium based IrO2 +Ta2O5 oxide anodes with different compositions and pyrolysis temperatures were prepared by termodecompoisition method. By using X-ray diffraction (XRD), the structure and texture coefficient of the coatings, TC(hkl), of IrO2 rutile crystal have been tested. It showed that, the crystallization processes of IrO2 and Ta2O5 in xIrO2 +(100-x) Ta2 O5 (x is in mol%) films affected and confined each other.In the mixed system, IrO2 rutile phase existed as a solid solution with Ta, and attained the maximum solubility when x=70mol%, i.e. for the coating of 70% IrO2 +Ta2O5.For the coatings of low iridium content or at low preparing tem pemture, (110) and (101) pwtered orientations were dominant. However, preferred growth of IrO2 weakened with increasing either iridium content or temperature. Three typical surface morphologies were observed by using scanning electron tnicroscopy(SEM). The crystallite size of the mixed oxide coatings were finest for the the film of 70%IrO2 +30%Ta2O5,and decreased with the pyrolysis tempemture. As the results of the finest crystallite segregating on sudece and the maxitnum solid solubility of Ir and Ta component in deposits, the coatings with the composition of 70%IrO2 +Ta2O5 prepared at 450℃ presented the mdrimutn electrocatalgtic activitg for O2 evolution in 0. 5M H2SO4 solution.UP to 550℃, Ti base suffered to oxidation resulting in decreasing anode conductivity,therefore, coatings performed a low activity.J.M Hu J.X.

6浅谈刘渊的血统和石勒的姓名显示文摘在蛮族征服西晋王朝的过程中,两位杰出的少数民族首领成功地运用了正统的象征,来证明他们的政权和统治是合法的。关于刘渊的家世渊源有三种说法,其中刘渊选择了自己是汉王室与匈奴贵族后裔的特殊血统。而石勒则为了利用当时的预言传说而以“石”为姓,以“勒”(铭文、碑文之义)为名。无论是刘渊,还是石勒,他们的姓名背后都隐含着标志自己政权合法、正统的含义。在中国历史上,刘渊(250—310)被称为公元四世纪“五胡乱华”的首领。D.B.霍尼 谢萌珍 1993国外社会科学1993,,1:3
7EFFECT OF SnO_2 ADDITION ON THE SERVICE LIFE AND ELECTROCHEMICAL PROPERTIES OF Ti/IrO_2,+Ta_2O_5 ANODES IN PHENOLSULFONIC ACID SOLUTION显示文摘Service life of two different oxide anodes in phenolsulfonic acid (PSA) solution was investigated by accelerated electrolysis. The durability of Ti/IrO2+Ta2 O5 anode increased by the addition of SnO2 in the mixed oxides. The degradation mechanisms of Ti/IrO2+ Ta2 O5 and Ti/IrO2 +Ta2 O5 +SnO+2 anodes were different. It was shown from the observation of scanning electron microscopy (SEM) and the electrochcmical measurement that, the deactivation of Ti/IrO2 + Ta2 O5 anode was due to the build-up of an organic film on surface. The growth of the covered film on surface was restricted by addition of SnO2, which resulted in increasing of the service life of anodes. The over-potential for oxygen evolution on Ti/IrO2 +Ta2 O5 electrode increased after doping SnO2, and the intermediate products of PSA building-up on the surface was much more rapidly oxidized. Meanwhile, a certain part of the surface oxide deposit entered into the solution leading to loss of oxides, which resulted in degradation of Ti/IroO2 + Ta2 O5 anode containing SnO2 component.J.M.

13Analytical and numerical modeling for the effects of thermal insulation in underground tunnels显示文摘The heat How generated from the infinite rock mass surrounding the underground tunnels is a major cause for the increasing cooling demands in deep mine tunnels.Insulation layers with lower thermal conductivities on tunnel walls and roof ceilings are believed to supply a thermo-barrier for heat abatement.However,it is found that no systematic theoretical investigations were made to predict and confirm the effectiveness of underground thermal insulation.Specifically,investigations on the underground insulation problems involving heat flows through the semi-infinite hot rock mass and insulation layer were not sufficient.Thus,in this paper,the thermal characteristics,accompanied with heat flow through the semi-infinite rock mass and the insulation layer,were modeled by both analytical and numerical methods with focus on underground mine tunnels.The close agreements between models have indicated that the thermal insulation applied on tunnel surfaces is able to provide promising heat abatement effects.Liu W.V.

16THE INFLUENCE OF Mo DIFFUSION ON THE THERMAL BEHAVIOR OF TBCs ON Ni_3Al BASED ALLOY IC-6显示文摘Conventional two-layered structure thermal barrier coatings (TBCs) were preparedonto γ'-Ni3Al based alloy IC-6 by electron beam physical vapor deposition (EB-PVD).Isothermal oxidation and thermal cycling tests were carried out to investigate theeffect of Mo content at the interface between bond coat and ceramic top coat causedby diffusion. It has been found that the alloy coated with TBCs presented the lowestoxidation weight gain value for the reason that the ceramic top coat in TBC systemcan effectively stop Mo oxides evaporating. The life time of TBCs has close relationwith Mo content at the interface between the bond coat and top coat. Spallation ofceramic top coat occurred during thermal cyclic testing when Mo atoms accumulatedat the interface up to certain amount to decline the combination between the bond coatand top coat.D.B.

17非ST段抬高型急性冠状动脉综合征患者中的肥胖矛盾现象:来自CRUSADE(对不稳定型心绞痛患者进行快速风险分层能否减少早期实施ACC/AHA指南的不良预后)质量改进研究的结果显示文摘Background: Although obesity is a known risk factor for coronary artery disease, its impact on the presentation, treatment, and outcome of patients with acute coronary syndromes(ACS) has not been well studied. Methods: Using data from the CRUSADE Initiative, we compared inhospital treatments and clinical outcomes of 80 845 patients with high-risk non-ST-segment elevation(NSTE) ACS(positive cardiac markers and/or ischemic ST-segment changes) to determine whether there was an association with body mass index(BMI[kg/m2]). Patient weights were categorized according to World Health Organization classifications: Underweight(BMI< 18.5), Normal range(BMI 18.5-24.9), Overweight(BMI 25-29.9), Obese Class I(BMI 30-34.9), Obese Class Ⅱ(BMI 35-39.9), and Extremely Obese(BMI≥40). Results: Most(70.5%) of the CRUSADE patients were classified as overweight or obese; these patients were younger and more likely to present with comorbid conditions, including diabetes mellitus, hypertension, and hyperlipidemia. Medications given during the first 24 hours and invasive cardiac procedures recommended by the American College of Cardiology/American Heart Association guidelines for NSTE ACS were more commonly used in these patients. The incidence of death and death and reinfarction, adjusted for covariates, were generally lower in overweight and obese patients, compared with normal-weight patients, but higher in underweight and extremely obese patients. Conclusions: Most patients with NSTE ACS are overweight or obese. These patients receive more aggressive treatment, and, except for the extremely obese, have less adverse outcomes compared with underweight and normal-weight patients. Although obesity appears to be a risk factor for developing ACS at a younger age, it also appears to be associated with more aggressive ACS management and, ultimately, improved outcomes.Diercks D.B.
