本文论述了彩色感光材料如:彩色相纸、彩色负片的冲洗加工过程中,彩色显影液被漂定液、漂白液或定影液污染后对彩色感光材料照相性能的影响;实践证明,即使仅仅在彩色显影液中混入微量的漂定液、漂白液或定影液,也会产生严重的影响,表现在特性曲线的主要指标上,如:灰雾、低密度级、高密度级、反差、黑块等。因此,一旦发现这种污染,应立即彻底清洗冲洗加工系统并更新彩色显影液,同时应查找原因,杜绝事故。  相似文献

在硝酸(1+9)溶液中,磷酸根与钒钼酸铵形成稳定的磷钼钒络合物,经显色后可测定磷。遇到富铁矿石时,可加入5%KF溶液掩蔽干扰。该方法适用于磷质量分数在1.0%以下地质样品的快速测定。  相似文献

Planning gain has long been used in Britain for infrastructure funding and has been increasingly used to secure land and funding from private developers for new affordable homes. This paper examines the theoretical and policy underpinnings of planning gain. It describes the growth in the number of new affordable, including intermediate, homes delivered through planning gain, the variations between planning authorities in the incidence of planning gain and the value of the contributions developers make. In the light of the environment after the credit crunch it considers the extent to which planning gain mechanisms can any longer deliver new affordable homes.  相似文献

This review paper introduces a research agenda designed to invigorate interest in information economics as a conceptual framework within which to analyse the purported transition from regulatory land-use planning, such as that operating in England prior to 2004, to “spatial planning”. In considering one specific area of reform—the management of infrastructure provision—a research agenda is introduced to investigate a specific policy instrument, the Community Infrastructure Levy. It is approached as a transaction cost, the determination of which is a function of how information is traded between counterparties. In conceptualizing important information asymmetries between local planning authorities and the development industry a case is made for further empirical research.  相似文献

无碳复写纸的发展趋势   总被引:1,自引:0,他引:1  
王际德 《中华纸业》2007,28(10):41-44
论述了国内外无碳复写纸的生产,技术概况,对中国无碳复写纸生产怎样发展问题进行了探讨。世界无碳纸的产量达到顶峰后出现了逐步衰减的情况,中国无碳纸还有较大的发展空间,近几年的生产能力一直在增加,但是需求下滑的局面在我国将来也会出现。企业应在提高质量和效率、增加功能、降低成本上下功夫。  相似文献

硫化物标准配制与测定方法可靠性研究   总被引:1,自引:0,他引:1  
采用40g/LNaOH吸收气态H2S后的溶液或用不含结晶水的固体硫化钠配制硫化物标准.标准液中硫量基本是以S2-形式存在的量.用三种方法对不同种类含硫物质进行了测定比较:碘量法直接滴定水中硫化物,其结果一般偏高;对氨基二甲基苯胺比色法直接测定水中硫化物,其结果一般偏低;S-XYX气化光度法直接测定水中硫化物时,其测定结果与水样中硫(S2-)化物含量基本一致,不受其他价态硫化物存在的影响.  相似文献

The rapid pace of wind power development in the USA over the last decade has outstripped the ability of most project developers to provide adequate equity capital and to make efficient use of project‐related tax benefits. In response, the sector has created novel project financing structures that feature varying combinations of equity capital from project developers and third‐party tax‐oriented investors and, in some cases, commercial debt. While their origins stem from variations in the financial capacity and business objectives of wind project developers, as well as the risk tolerances and objectives of equity and debt providers, each structure is, at its core, designed to manage project risk and to allocate federal tax incentives to those entities that can use them most efficiently. This paper surveys the six principal financing structures through which most new utility‐scale wind projects (excluding utility‐owned projects) in the USA have been financed from 1999 to the present. These structures include simple balance sheet finance, several varieties of all‐equity special allocation partnership ‘flip’ structures and two leveraged structures. In addition to describing each structure's mechanics, the paper also discusses its rationale for use, the types of investors that find it appealing and why, and its relative frequency of use in the market. The paper concludes with a generalized summary of how a developer might choose one structure over another. Copyright © 2008 US Government Work.  相似文献
