| 2 | Difference in the Hot Compressive Behavior and Processing Maps between the As-cast and Homogenized Al-Zn-Mg-Cu(7075) Alloys显示文摘The deformation mechanisms and processing maps of the as-cast Al-Zn-Mg-Cu(7075) aluminum(Al)alloy were studied and compared with those of the homogenized 7075 Al alloy in the temperature range of 573–723 K and in the strain rate range of 10^(-3)–10 s^(-1) to explore a possibility for directly using the ascast 7075 Al alloy as a billet for hot working. The as-cast and homogenized 7075 Al alloys had similar grain sizes and showed similar high-temperature deformation behaviors. The as-cast 7075 Al alloy, however,exhibited higher power efficiencies and smaller unstable ?ow regions compared to the homogenized 7075 Al alloy because of the presence of secondary phases(Mg Zn_2) segregated at the dendritic interfaces in the as-cast microstructure, which were formed during non-equilibrium solidi?cation. These segregated phases provided nucleation sites for dynamic recovery or continuous dynamic recrystallization, and as a result a ?ne and more homogeneous(sub)grain structure could be obtained from the as-cast microstructure compared to the homogenized microstructure. The current work suggested the possibility and advantage of using as-cast microstructures for hot working of aluminum alloys with high content of solutes. | S.Y. Park W.J.

| 3 | 全氟取代的钛酞菁衍生物的非线性光学和光限幅性能研究显示文摘制备和研究了全氟取代的钛酞菁F_(16)PcTiO及其轴向取代衍生物F_(16)PcTiO_2PhCHO的线性和非线性光学(含光限幅)性能。与F_(16)PcTiO相比,轴向取代的钛酞菁F_(16)PcTiO_2PhCHO的Q带最大峰红移了7 nm。Z-扫描实验表明,无论在甲苯溶液中还是在氯仿溶液中,F_(16)PcTiO都展现出比F_(16)PcTiO_2PhCHO更大的非线性吸收系数和低的饱和能量密度。F_(16)PcTiO_2PhCHO在氯仿溶液中的光限幅性能要明显优于其在甲苯溶液中的光限幅性能。与高度可溶的四叔丁基取代的钛酞菁(tBu_4 PcTiO和tBu_4 PcTiO_2 PhCHO)相比,十六氟取代的钛酞菁化合物具有较强的由酞菁环间范德华力驱动的分子间相互作用,这种相互作用导致材料在有机溶剂中的溶解度降低和非线性性能(含光限幅)性能下降。 | 高丽丽 陈彧 何楠 刘莹 Wang Jun Blau W.J. | 2010 | 光学学报2010,30,4: | 10 |
| 4 | Experimental and Numerical Investigation on Impact Performance of Carbon Reinforced Aluminum Laminates显示文摘It is known that fiber metal laminates (FML) as one of hybrid materials with thin metal sheets and fiber/epoxy layers have the characteristics of the excellent damage tolerance, fatigue and impact properties with a relatively low density. Therefore, the mechanical components using FML can contribute the enhanced safety level of the sound construction toward the whole body. In this study, the impact performance of carbon reinforced aluminum laminates (CARAL) is investigated by experiments and numerical simulations. Drop weight tests are carried out with the weight of 4.7 kg at the speed of 1 and 2 m/s, respectively. Dynamic non-linear transient analyses are also accomplished using a finite element analysis software, ABAQUS. The experiment results and numerical results are compared with impact load-time histories. Also, energy-time histories are applied to investigate the impact performance of CARAL. | S.H. Song Y.S.

| 5 | 为了历史的记录——访罗尔斯显示文摘罗尔斯的好友和哲学同事R .阿尔布莱顿 (RogersAlbritton)在描述罗尔斯时说道 :“我对杰克 ② 的主要感觉是 ,他是一个值得信赖的人 ,在他讨论其他人的时候具有很强的道德感。他不仅仅写出了巨著 ,而且是一个非常值得钦佩的人。他是我们中的佼佼者。”③ 罗尔斯发表于 1 971年的《正义论》一直被看作是现代政治哲学中的转折点 ,因为它复兴了哲学研究中的重要领域。它也是最为全面和具有深远影响的现代自由主义巨著。该书 2 0余万册在全球范围内销售一空 ,有 50 0 0余部论著专门讨论它 ,这些惊人的事实正是由于《正义论》是一部严谨而深刻的理论著作。罗尔斯在他的论著中对他的个人生活始终守口如瓶 ,但对他人的帮助和观点却感激不尽。他回绝了大多数的采访 ,只接受了与他始终保持个人关系的某些大学的荣誉学位 ,如牛津大学、普林斯顿大学和哈佛大学。他很长时间都没有同意把他的名字收入《名人录》。以下的采访见于 1 991年的《哈佛哲学评论》 ,是罗尔斯作过的仅有的三次访谈之一 ,而这三次访谈都是与现在或以前的学生进行的。罗尔斯的个人生活完全奉献在关于社会正义、合作和个人权利等问题的思考、教学和写作当中。罗尔斯于 1 92 | S.R.艾芭 J.D.哈兰 W.J.李 江怡 | 2003 | 世界哲学2003,,2: | 5 |

| 10 | 论历史的实践领域——科林伍德的哲学显示文摘讨论到科林伍德关于历史的实践领域的观点,有三个方面似乎是应该辩明的:历史在人类认识自我中的作用,历史在认识现实中的作用,以及历史在认识人类本性中的作用。我们准备简要地讨论这三个方面。如其在自传中所强调的那样,科林伍德认为历史的重大价值就在于“在史学方法上的革命……产生了真正的、实际的、显著的和迅速的知识进步,这种进步第一次使人类能够象圣哲的箴言所教导的那样去认识自己”。不过,我觉得科林伍德在别处所提出的唯有通过历史人才能认识自身的说法有些夸张。在《人性和历史》的手稿中。 | W.J.冯.德.达森 刘昶 | 1982 | 国外社会科学1982,,12: | 3 |

| 12 | Antimicrobial Activity of Ulva reticulata and Its Endophytes显示文摘Seaweeds are known to exhibit various antimicrobial properties,since it harbours an enormous range of indigenous bioactive compounds.The emergence of drug resistant strains has directed to the identification of prospective metabolites from seaweed and its endophytes,thereby exploiting the properties in resisting bacterial diseases.The current study was aimed to assess the antimicrobial activity of extracts obtained from Ulva reticulate,for which metabolites of Ulva reticulata and its endophytes were extracted and assessed against human pathogens like Staphylococcus aureus,Escherichia coli,Pseudomonas aeruginosa,Salmonella typhi,and Bacillus subtilis.It was observed that the hexane extract of isolate VITDSJ2 was effective against all the tested pathogens but a significant inhibition was observed for Staphylococcus aureus and Escherichia coli.Further,Gas chromatography coupled with Mass spectroscopy(GC-MS) revealed the existence of phenol,3,5-bis(1,1-dimethylethyl) in the crude hexane extract which is well-known to possess antibacterial activity.The effective isolate VITDSJ2 was identified to be the closest neighbour of Pseudomonas stutzeri by phenotypic and genotypic methods.The crude extracts of the seaweed Ulva reticulata was also screened for antibacterial activity and the hexane extract was effective in showing inhibition against all the tested pathogens.The compound in the crude extract of Ulva reticulata was identified as hentriacontane using GC-MS.The extracts obtained from dichloromethane did not show significant activity in comparison with the hexane extracts.Hence the metabolites of Ulva reticulata and the bacterial secondary metabolites of the endophytes could be used in the treatment of bacterial infections. | Dhanya K.I.

| 20 | First-principles Calculation Assisted Thermodynamic Modeling of Ti-Co-Cu Ternary System显示文摘Thermodynamic assessment of Ti-Co-Cu ternary system has been carried out by combining first-principle calculation and CALPHAD method. Firstly, formation enthalpies of stable and hypothesized compounds were calculated by first-principles method. Then, based on reported experimental information, a thermodynamic description of the Ti-Co-Cu ternary system was performed. Solution phases were treated as substitutional solutions of which excess Gibbs energies were formulated by Redlich-Kister polynomial, and the intermediate phases were described with sublattice models. All measured isothermal sections were reasonably reproduced. In addition, liquidus projection of this ternary system was further calculated, which may be useful for relevant materials processing. | Y.J. Yang X.M. Tao W.J. Zhu Z.H. Long H.S. Liu Z.P.
