为寻找更有效率的动态Agent调度方法,提出一个不使用合同网机制的多Agent流式调度模型;与通过拍卖实现动态调度不同,模型将机器的工时以流的形式提供给作业Agent进行选择。该模型很好地规避了合同网模型在调度时因投标并发操作导致调度质量下降的问题,同时大大减少了所需的网络通信资源,提高了调度效率。模型还在资源Agent的运算过程中增加了优化模块,在保证调度软实时性的前提下提高了调度质量。通过实时仿真测试验证了流式调度模型的效果。

为了研究纳米γFe2O3催化剂选择性催化还原法（SCR）脱硝反应机理,采用微分反应器测量了纳米γFe2O3催化剂上SCR反应的动力学参数,并构建了SCR反应动力学模型.实验数据分析结果表明,NH3,NO和O2的反应级数分别为0,0.78~0.93和0.09~0.11,反应活化能为57.3 k J/mol.原位红外漫反射光谱（DRIFTS）实验结果表明：NH3能够强吸附到催化剂表面并达到饱和,进一步增加NH3的浓度并不能增加NO的转化速率;NO在有氧条件下能吸附到催化剂表面生成吸附态NO2和亚硝酸盐;在低于270℃的情况下SCR反应遵循Langmuir-Hinshelw ood（L-H）反应机理,在高于270℃的情况下则主要遵循Eley-Rideal（E-R）反应机理.

作者：谢志勇 Tianjin University

Cordierite precursor was obtained through a process, which involved the decomposition of metal nitrates on the surface of ultrafine carbon black powder between 100-300℃ and the gasification of the carbon black at higher temperature in air. The average size of the particles, which were heat-treated at 700℃ for 10h, is about 1020nm, and the specific surface area is about 129m 2/g. The experimental results show that the ultrafine particles of cordierite precursor can be produced by this process. The precursor powder was calcined at different temperatures. X-ray diffraction examination indicates that β-quartz is crystallized from the amorphous matrix around 850℃ firstly and then MgO-Al 2O 3 spinel and α-cordierite appears. Above 1000℃, MgO-Al 2O 3 spinel and cristobalite disappear gradually and form an intermediate phase (sapphirine). At around 1300℃, the main phase is α-cordierite, and no other phase is detected.

Two diadochy cyanide-bridged bimetallic complexes [Pr(DMSO)2(H2O)3Co(CN)6] ?H2O 1 and [Nd(DMSO)2(H2O)3Co(CN)6]?H2O 2 have been synthesized, and their crystal structures were determined by single-crystal X-ray diffraction methods. Crystal data for 1: monoclinic, space group P21/c, a = 7.692(2), b = 30.791(10), c = 9.131(3) ?, β =100.645(5)o, V = 2125.4(11) ?3, Z = 4, the final R = 0.0422 and wR = 0.0904 for 3484 observed reflections with I > 2σ(I); and those for 2: monoclinic, space group P21/c, a = 7.692(3), b = 30.902(11), c = 9.152(3) ?, β = 100.665(5)o, V = 2137.8(13) ?3, Z = 4, the final R = 0.0515 and wR = 0.0906 for 3268 observed reflections with I > 2σ(I). The LN atoms are linked to the Co atoms by cyanide bridging, forming a two-dimensional gridding structure. The LN3+ ions are both eight-coordinated by three cyano nitrogen and five oxygen atoms of two DMSO and three water molecules. The X-ray single-crystal structure analysis shows that the unbridged cyanide ligands between the closest layers interact with the coordinated water molecules through hydrogen bonds to connect the two layers. Therefore, the molecular structure is a 3D hydrogen-bonded network derived from LNCo chains.

The authors performed ionic liquid-based microwave-assisted liquid-liquid microextraction（IL-based MALLME） coupled with high performance liquid chromatographic separation for the determination of 6 sulfonamides （SAs） from animal oils. The target analytes were extracted from animal oil samples with sodium hydroxide solution containing 1-butyl-3-methylimidazolium tetrafluoroborateand as the extraction solvent under microwave irradiation. The experimental parameters of the IL-based MALLME, including types of ILs, volume of IL, amount of ion-pairing agent（NHaPF6）, pH value of sample solution, and extraction temperature and time were evaluated. The limits of detection and quantification obtained were in a range of 0.4--0.5μg/kg and a range of 1.2--1.8μg/kg, respectively. The accuracy of the method was evaluated by analyzing five spiked animal oil samples at two fortified levels（5 and 50μg/kg）, and the recoveries of SAs varied from 81.4% to 114.5% with relative standard deviations ranging from 0.8% to 9.0%.
