活性炭对4—氨基安替比林提纯作用的评定——针对水质监测中对挥发酚的监测分析

在挥发酚的监测分析中,本文通过应用苯与活性炭分别对显示剂4-氨基安替比林(C11H13N3O)做去渣、脱色对比实验,阐明了活性炭对4-氨基安替比林(C11H13N3O)显示剂的去渣、脱色作用无论是在分析的操作上,还是对人体的毒性、分析成本和再生性上都比用苯(C6H6)对其进行处理具有优越性。并通过近三年的实验,验证了其精确性和准确性,说明利用活性炭替代苯对显色剂进行预处理,能够符合我国《水和废水监测分析方法》和《环境水质监测质量保证手册》的相关要求。     

Synthesis, Characterization and Calorimetry of Ni（C4H8N2O3）2Cl2

A coordination complex was synthesized from NiCl2 and dipeptide glycylglycine（GG）. It was characterized by element analysis, NMR and TG methods, and then was determined to be Ni（C4HsN2O3）2Cl2. Using an isoperibolic reaction calorimeter, the standard molar enthalpy of formation of Ni（GG）2Cl2（solid） has been determined to be -（1 674.66±2.02） kJ · mol^-1 at 298.15 K.     

加碳方式对磷酸铁锂动力学及电化学性能的影响

以FeSO4.7H2O和NH4H2PO4为原料,以H2O2为氧化剂,通过液相沉淀法制得前驱体FePO4,然后通过碳热还原反应制得LiFePO4。采用2种加碳方式:方法一是先制得FePO4,然后加入乙炔黑混合后高温合成LiFePO4;方法二是先把乙炔黑分散在液相中,然后通过液相沉淀制得含碳的FePO4,再高温合成LiFePO4。研究结果表明:采用方法二合成的LiFePO4动力学及电化学性能比方法一合成的优。采用方法二所制备的LiFePO4样品以0.1C的倍率放电,其比容量达149 mA.h/g;当放电倍率为1C时,其比容量为124 mA.h/g,且循环性能良好。     

Eph受体家族和Ephrin-A5在NSCLCs中上调表达及其临床意义(英)

采用荧光实时定量PCR的方法在48个非小细胞肺癌组织以及配对的正常肺组织中检测Eph/ephrin 基因的mRNA水平.发现肺癌组织中EphB4, EphB3 和 ephrin-A5的表达水平与配对的正常肺组织相比分别上调了60%，81%和65%,并具有显著的统计学差异. 而且，统计学分析发现ephrin-A5的表达水平与肿瘤分型、转移、性别、吸烟以及诊断年龄等临床病理学参数之间存在显著的相关性.此外，EphA2的表达水平与肿瘤大小、家族遗传史以及诊断年龄之间也存在显著的相关性.总之，这些结果提示EphB4, EphA2, EphB3 和ephrin-A5 在肺癌的发生和发展过程中可能以一种单独或者协同的形式发挥作用.这些蛋白有可能成为研究和诊断肺癌的重要靶向基因.     

活性炭对2，4-二氯苯酚的催化臭氧化降解

研究了粒状活性炭（GAC）对2，4-二氯苯酚（2，4-DCP）臭氧化降解的催化性能。由于活性炭的吸附和催化作用，提高了2，4-DCP的分解。在酸性条件下具有较高的催化臭氧化效率，而酸性和碱性的强弱对2，4-DCP的分解几乎没有影响。活性炭的重复使用实验表明活性炭在臭氧化处理过程中可以得到原位再生，多次使用后其催化活性几乎没有降低。     

Fe3O4／聚（丙烯酸甲酯-二乙烯苯）微球对金属离子的吸附

通过悬浮聚合制备Fe3O4／聚（丙烯酸甲酯-二乙烯苯）磁性微球，考察了微球对金属离子的吸附性能。结果表明，磁性吸附剂粒径35—55μm，Fe3O4质量分数18％，能有效吸附金属离子。由Langmuir模型得到的饱和吸附容量为别为：Hg2＋2．3mmol／g,Cu^2＋2mmol／g，Ni^2＋ 1．1mmol／g。由Lagergrent方程计算的吸附速率常数分别为：Hg^2＋0．023min^-1，Cu^2＋0．034min^-1，Ni^2＋0．036min^-1。吸附剂可用1mol／LH2SO4再生。

社科学报投稿摘要写作中常见问题及对策

摘要是论文的精华所在,是对论文所做的扼要概述,应能客观反映论文的主要内容信息。根据学报（社科版）2007—2010年的投稿情况,分析发现投稿在摘要写作方面主要存在摘要像引言或与引言重复;出现＂本人＂＂我们＂＂作者＂＂本文＂＂笔者＂作为陈述主语;摘要写作中不乏评价性语言过于简单,没有涵盖文章中心内容,读者无法了解全文信息等问题。因此,应高度重视摘要写作规范,遵循科技论文写作的国家标准和规范要求及不定期开设规范化专题讲座等,使作者写出可供发表的规范化文稿。     

Hexavalent Chromium Adsorption from Aqueous Solution by Agricultural Waste Materials

Abilities of agricultural waste materials (walnut shell-WS, rice husk-RH, and peanut hull-PH) were tested as adsorbents for the adsorption of Cr(Ⅵ) from aqueous solution. Batch adsorption experiments were carried out to study the adsorption kinetics mechanism of Cr(Ⅵ) effect of adsorbent dosage, pH, contact time, and temperature. The best results are obtained at 15g/L adsorbent concentration, 60min contact time, 298K temperature, and 50mg/L adsorbate initial concentration at pH 2. The adsorption isotherms, using initial concentrations of Cr(Ⅵ) between 10 and 500mg/L for the Cr(Ⅵ) removal, show the maximum metal uptake capacities of adsorbent were 10.48, 6.71, and 8.54mg/g for WS, RH, and PH, respectively. And the adsorption data fitted well to the Langmuir adsorption isotherm for WS, RH, and PH with correlation coefficients of 0.9862, 0.9723, and 0.9714, respectively. Moreover, the FTIR analysis of WS, RH, and PH before and after adsorption of Cr(Ⅵ) suggested that Cr ions were combined to some functional groups of compounds contained in these materials.     

Coordination Model Research Based on Command Decision Joint Intension

Command Decision Simulation （CDS） is not only an important and difficult issue in the field of simulation, but also a technique issue to be tackled in the course of collective Modeling and Simulation in Joint Operations Experiment Center. CDS can give support to all kinds of simulation. Using computer to realize the Blue side＇s command deci- sion automatic execution in the operation training simulation system can improve training effect. Using computer to realize the lower level command unit＇s automatic command deci- sion can help to reduce the number of controllers and release them from heavy work. It can also enlarge simulation scale and increase the freedom of the simulation entity especially the command entity, thus enhance the authenticity and credibility of the simulation. Ac- cording to the command decision structure and the Joint Intention Theory, the thesis puts forward the method of making use of Coordination Matrix （CM） to realizing cooperation among the entities in CDS and constructs the calculation sketch of Task Execution, Task Monitoring and Task Replanning. At the same time, the thesis brings forward the CDS structure vision based on Partial Global Planning（PGP）. As CM is an indispensable part of combat simulation, the theory and the method of CDS will become an important part for the theory of Combat Simulation.
