文献检索报告任务书一、课题简要说明The electrostatic rotary atomizer has the highest paint efficiency in all kind of atomizers. The usage of an electrostatic rotary atomizer, therefore, has contributed to reduce the waste of paint and volatile organic compounds (VOCs). Concurrently, water-borne painting processes which usewater-soluble paint have been introduced to reduce the amount of VOCs emissions. With the water-borne painting, the atomizer body is easily contaminated by the paint mists. The contamination has been an important problem to be solved in factories.二、专题检索报告Water absorption is an essential parameter to define the protection properties of anticorrosive paints. This parameter is often evaluated by means of the dielectric capacitance of the coating. The presence of water in the coating increases its dielectric constant. The semi-empiricalBrasher-Kinsgbury equation [1] allows the estimation of a coatingpsilas water uptake through capacitance measurements. However, the capacitance of a coating depends, at least, on both the amount of water (volume fraction) and the shape of the water inclusions [2]. Brasher-Kingsbury approximations may result in highly inaccurate values. Therefore, it is interesting to have a direct measurement of the mass increment of the coating together with the time evolution of its dielectric capacitance. A stable quartz crystal oscillator sensor for measuring the water uptake in organic coatings was designed. The phase noise performance of the oscillator has been investigated in order to characterize the oscillatorpsilas resolution during the water uptake process. The result is a quartz crystal microbalance (QCM) sensor able to determine the rate and amount of water absorbed into anticorrosion cataphoretic coatings with a resolution of 360 pg/cm2 for one second sampling interval.Electrostatic corona painting on nonconductive surfaces normally requires a ground-connected conductive precoating of the surface in order to dissipate the continuously incoming ionic charge from the corona gun. If the surface charge does not flow to ground, the resulting surface electric field will repel a substantial amount of the incoming paint. The authors present a new painting method consisting of generating ultrasonically atomized electrically charged water particles behind the nonconductive surface to be painted.

The interest has expanded to include ecologically significant groups and major biomass producers using mesocosm studies, emphasizing species interactions. This paper assesses the effects of UV-B radiation on dissolved organic matter, decomposers, primary and secondary producers, and briefly summarizes recent studies in freshwater and marine systems.2、Impacts of clearing invasive alien plants from 1995 to 2005 on vegetation structure, invasion intensity and ground cover in a temperate to subtropical riparian ecosystem?M.M.T. Beater, R.D. Garner, E.T.F. Witkowski?Restoration and Conservation Biology Research Group, School of Animal, Plant and Environmental Sciences, University of the Witwatersrand, Private Bag 3, Wits 2050, Johannesburg, South Africa?Received 7 August 2007. Accepted 22 January 2008. Available online 17 March 2008. Edited by DM RichardsonAbstractThe impacts of invasive alien plants (IAP) and their subsequent clearing by the Working for Water Programme (WfW) on (a) overstorey (woody plant) vegetation structure, (b) invasion intensity(overstorey aerial cover of woody alien plants) and (c) ground cover, in a temperate to subtropical riparian ecosystem were studied in 1996/7 and again in 2005, in order to provide a longer-term perspective on the effectiveness of WfW clearing. Forty 1000 m2 plots were surveyed and resurveyed, comparing between (a) higher altitude Grassland and lower altitude Savanna, (b) high (> 50% invasion intensity) versus low (< 50% invasion intensity) alien invasion sites, and (c) WfW cleared versus uncleared sites (the three ‘treatments’). Pre-clearing estimates from cut stumps in 1996/7 indicated high alien invasion intensities of 72 ± 8% in Grassland and 69 ± 11% in Savanna. From 1996/7 to 2005 there was a large decrease in aerial cover of alien trees of > 5 m and to a lesser extent 2–5 m in height, and a large increase in alien plants of < 2 m. Hence WfW was initially successful, with the original tall Eucalyptus grandis tree layer largely removed. However, total invasion intensity remained unchanged over the first decade (30.4 ±4.6% in 1996/7, 31.9 ± 3.2% in 2005). From 1996/7 to 2005, grass and herbaceous cover decreased, while bare soil and litter increased, indicating reduced surface stability. This was in response to (a) the major flood event of February 2000, (b) the effects of IAP invasions and (c) WfW clearing. Total ground vegetation cover was negatively related to alien aerial cover in both biome reaches in 1996/7 and 2005. By 2005, there were no longer any differences in the aerial cover of woody alien plants in response to the original 1996/7 invasion intensity or clearing ‘treatments’, and hence progressive homogenization of IAP cover. Aerial cover of woody indigenous plants also responded negatively to increasing alien aerial cover in 1996/7 and 2005 in both Savanna and Grassland. In conclusion, the nature of the IAP problem has changed from dealing largely with relatively few large E. grandis trees in the mid-90s, to the present large suite of invasive species with numerous smaller individuals. This has implications for the time needed for clearing. This is one of few studies to have assessed the initial and longer-term (1995–2005) effectiveness of WfW clearing operations. It shows that improved IAP clearing protocols are needed. More follow-up treatments are recommended to ‘capture’ alien resprouts and new seedlings before they establish and reproduce. Secondly, integrating clearing with restoration of the tall indigenous riparian canopy tree species in heavily invaded sites would help to shade out many alien recruits.3、Biodiversity and ecosystem services in agricultural landscapes—are we asking the right questions??M.J.

IntroductionThe role of biological diversity in the provision of ecosystem goods and services and the way this role can be valued and managed during agricultural intensification is much debated but still poorly understood. A key problem in all debates on biological diversity is that the abstraction ‘diversity’ has often not been distinguished from the specific attributes of the community of organisms that is under study in any particular location or system. Likewise, evaluations of diversity have more often than not been assessments of the value of biological resources as such rather than assessments of the value of diversity per se (Nunes and van der Bergh, 2001). For instance, if the intere st lies in the functional roles of the community these may depend on the ‘structure’ of the vegetation and the relationships between different ‘functional groups’, rather than on diversity as such (Woodward, 1993). Experiments based on random species assemblages may be appropriate tests for hypotheses about ‘diversity’ per se, but tell us very little about the largely self-selected assemblages that make up natural ecosystems. In the case of agroecosystems, whilst the dominant crops or livestock are human choices, by far the majority of the species (as soon as one takes the below-ground part of the system into consideration) are self-selected. So, are we asking the right question about the relations between biodiversity and ecosystem services? Does the loss of diversity at plot-to-global scales imply a threat to critical ecosystem functions? Can we identify thresholds in such a process?末段：We have defined a functional group in the text as ‘a set of species that have similar effects on a specific ecosystem-level biogeochemical process’. There are many examples of classification of species in this way within specific taxonomic or trophic groups (e.g. for plants or pests). There is no single classification to suit all purposes. In each case it is clear that the number of functional groups that is recognised, the criteria that are used to classify them and the degree of subdivision that is applied is a function of the question that is being addressed. We propose here aclassification into the 10 major groups that are briefly described below, together with such subdivision as may be necessary, for the purposes addressed in this paper, i.e. the relationships between biodiversity and function with particular respect to agriculture and ecosystem services. These Key Functional Groups are listed in Table 1 in relation to the ecosystem services they provide. The relationships between them are shown in Fig. 4. We suggest that this could provide a useful framework for investigating and testing key questions on this topic. A hierarchical structure is suggested (Fig. 4). At the highest level are four major categories related to major trophic functions at the ecosystem scale, i.e. Primary Production, Primary Regulation, Service Provision and Secondary Regulation. At the next level are the 10 groups listed in Table 1 that perform distinct ecosystem functions; and at the third level are subdivisions which it may be functionally and/or taxonomically useful to distinguish (e.g. vertebrate grazers versus invertebrate pests among the herbivores). Further levels of subdivision may also be useful or necessary in some cases.七、参考文献：Allen and Starr, 1982Allen, T.F.H., Starr, T.B., 1982. Hierarchy: Perspectives for Ecological Complexity.

Evidence is provided for three of the six validity asp ects (content, substantive and generalizability) needed to su pport the construct validity of the NOSI-E. A future articl e will examine the structural and external validity aspects.Rasch modeling proved especially productive in scale improv ement efforts. The instrument, designed for large-scale asses sment use, is conceptualized using five construct domains. D ata from 741 elementary students were used to pilot the Ra sch scale, with continuous improvements made over three succ essive administrations. The psychometric properties of the NO SI-E instrument are consistent with the basic assumptions of Rasch measurement, namely that the items are well-fitting and invariant. Items from each of the five domains (Empiric al, Theory-Laden, Certainty, Inventive, and Socially and Culturally Embedded) are spread along the scale's continuum and appear to overlap well. Most importantly, the scale seems appropriately calibrated and responsive for elementary schoo l-aged children, the target age group. As a result, the NO SI-E should prove beneficial for science education research.As the United States' science education reform efforts mov e toward students' learning science through engaging in auth entic scientific practices (NRC, 2011), it will be important to assess whether this new approach to teaching science i s effective. The NOSI-E can be used as one measure of whe ther this reform effort has an impact.三、在CNKI中检索一篇本专业的博士论文，写出你选择的学科领域，检索结果数，摘录结果中序号与你学号末位数相同的那篇论文的题录信息。

It offers a narrative writing and a reflective writing of one student, Lisa, to demonstrate how the project worked in her efforts to investigate the nature of students, teaching and students' learning. It also points to some implications for English language arts teacher preparation. First, what kinds of pedagogies might support prospective English language arts teachers as they grapple with complex concepts, and how might teacher educators create "safe spaces" where these pedagogies then become possible? How might teacher educators locate themselves in the classroom in order to enact these pedagogies? Furthermore, how do projects such as the one described reflect visions--though arguably problematic--that can be developed into segments of teacher preparation curriculum in ways that support the knowledge base for teaching and that are also responsive to prospective teachers' perceived needs?.

邹申(1998∶1-21)研究了从1993年至1996年英语专业听力理解部分的内容效度，之后对该部分的研究比较缺乏，因此本文将从以下三个方面研究改革后(2005年至2009年)英语专业听力理解部分的内容效度：英语专业听力理解是否达到教学大纲(2000版)和考试大纲(2004版)对听力部分的要求；英语专业听力理解与教学大纲和考试大纲相吻合的程度；英语专业四级和英语专业八级听力内容的不同之处。
<br>基于Bachman和Palmer的任务特点框架(1999)，结合听力理解的理论实质，参照教学大纲和考试大纲对听力理解的要求，参考国内外听力理解内容效度研究成果，本文提出了一个结合英语专业四、八级听力理解实际的听力测试内容效度研究评估框架。
本文将从文本输入、预期回答、文本输入和预期回答的关系三方面分析从2005年至2009年英语专业四级和英语专业八级的16篇对话、15篇短文、42篇新闻、5篇讲座和4篇访谈。
<br>研究结果表明，2005年至2009年的英语专业听力理解部分的内容效度较高，覆盖了教学大纲和考试大纲规定的内容。
主要表现在以下两个方面：1)听力理解部分与教学大纲和考试大纲要求相一致性高。
