江汉平原印支期以来的盆山耦合关系及下古生界油气响应

利用构造地质学和油气系统理论，以盆地构造-沉积分析技术为手段，研究了印支期以来江汉平原与周缘造山带的耦合关系，探讨了江汉平原的构造演化及其对油气成藏的控制作用。印支期以来江汉平原及周缘经历了挤压、拉张、挤压3次大的构造应力场的转换，使古生代海相碳酸盐岩沉积为主的盆地具有改造盆地的特点；一方面强烈的抬升、剥蚀使早期聚集的油气经历改造和再分配、再聚集过程，另一方面燕山期构造活动使逆冲推覆构造成为该区重要勘探领域。综合分析表明，位于台、盆转换带的宜昌-珂理-簰州区带是目前江汉平原及周缘下古生界油气勘探的有利地区。     

Mass transfer kinetics of neodymium(III) extraction by calix[4]arene carboxylic acid using a constant interfacial area cell with laminar flow

BACKGROUND: Thermodynamics and kinetics data are both important to explain the extraction property. In order to develop a novel separation technology superior to current extraction systems, many promising extractants have been developed including calixarene carboxylic acids. The extraction thermodynamics behavior of calix[4]arene carboxylic acids has been reported extensively. In this study, the mass transfer kinetics of neodymium(III) and the interfacial behavior of calix[4]arene carboxylic acid were investigated. RESULTS: The rate constant (K_ao) becomes constant when the stirring speed was controlled between 250 rpm and 400 rpm. The activation energy (E_a) was calculated to be 21·41 kJ mol^?1 or 88·17 kJ mol^?1 (dependent on temperature) from the slope of log K_ao against 1000/T. The linear relationship between the specific area and the extraction rate is the characteristic of an interfacial reaction control. The minimum bulk concentration of the extractant necessary to saturate the interface (C_min) is lower than 4·19 × 10^?4 mol L^?1. CONCLUSION: The effect of stirring speed, temperature, and species concentration on the extraction rate demonstrates that the extraction regime depends on the extraction conditions. The chemical reaction control governs the extraction regime at temperatures below 303 K and a mixed control regime occurs when the temperature is between 303 K and 318 K. The probable locale for the chemical reaction is at the liquid–liquid interface and the rate equation is deduced to be: ? d[Nd³⁺]_(a)/dt = k_f[Nd³⁺]_(a)[H₄A]_(o)^0·727[H⁺]_(a)^?0·978. The rate‐controlling step was suggested by the analysis of the experimental results. Copyright © 2008 Society of Chemical Industry     

调节剂对烷基水杨醛肟萃取铜铁的影响

烷基水杨醛肟虽然是一种高选择性的铜萃取剂，但单独使用时，萃取相易出现沉淀；反萃时，再生有机相出现乳化物，而且两相分离时间较长．将月桂醇、仲辛醇、壬基酚三种调节剂分别加入到萃取剂中，研究其对烷基水杨醛肟萃取及反萃行为的影响．结果表明，三种调节剂均可以解决上述问题，只是使萃取能力略有降低；壬基酚加入到烷基水杨醛肟中有助于提高铜铁分离系数，可达647．

组织协同进化分类算法用于雷达目标一维像识别

针对雷达目标一维像识别问题，提出了一种基于组织协同进化分类算法的识别方法．该方法与现有进化分类方法的不同之处在于它的进化操作直接作用于样本而不是规则，采用了一种自下而上的搜索机制，即先使若干样本的集合得到进化，再从进化结果中提取规则．这样有利于避免在进化过程中产生无意义的规则．该方法不需要进行特征提取；对于高维数据，不需要预先进行降维处理；没有复杂的运算，训练和识别的速度都很快．对3种飞机微波暗室实测数据的识别实验表明，该方法性能稳定，优于基于支撑矢量机与子波核函数的方法，识别率均达到了96％以上．实验中还对算法的抗噪能力进行了测试，获得了良好的效果．

The Locus of Redundant-Targets and Nontargets Effects: Evidence From the Psychological Refractory Period Paradigm.

In target detection tasks, responses are faster when displays have 2 targets (redundant-targets effect; RTE) and slower when they have no targets (nontargets effect; NTE) relative to displays with a single target. The psychological refractory period paradigm was used to localize these effects. In Experiment 1, participants classified tones as high or low and then classified letters as targets or nontargets after a short or long stimulus onset asynchrony (SOA). The magnitudes of the RTE and NTE did not depend on SOA. In Experiment 2, the order of the tasks was reversed, and at short SOAs the RTE and NTE had similar magnitudes for both tone discrimination and target detection responses. These findings suggest that the RTE and NTE arise during response selection. Interactive effects of tone pitch with the number and type of target features were also observed, and these were tentatively interpreted as synesthetic effects.

根据油田采出水的水质特征，采用厌氧(水解)-好氧(接触氧化)处理工艺。实验表明，虽然油田采出水的BOD5／CODCr，较低，属于难生物降解废水，但是当温度为50～60℃时，选择厌氧停留时间为6h，好氧停留时间为3．5h，气水比为10～20，可使其出水的CODCr稳定在120mg／L左右。如果排除Cl^-产生的影响，CODCr，约为60～70mg／L，达到GB8978-1996一级排放标准。
