哥本哈根会议的得失和昭示

哥本哈根会议是一系列全球气候变化会议中最重要的会议,背负着全人类的重托和冀望,虽然此次会议取得了一些重要进展,但因其不具有法律约束力和未提及具体温室气体减排目标,使得相关利益诉求并未得到满意的平衡。会议昭示我们,中国碳减排和低碳经济发展任务十分艰巨,需要切实可行的新思路。     

离子色谱在无机炸药分析中的应用

建立硝铵、氯酸盐炸药和黑火药中无机阴阳离子的定性定量分析方法,为爆炸案件或事故中炸药成分的分析提供分析方法。得出了常见无机炸药中NO3-、NO2-、SO32-、S2O32-、SO42-、ClO3-、Cl-等阴离子的色谱分析条件和NH4+、Na+、K+等阳离子的色谱分析方法。应用离子色谱法对无机炸药中常见阴、阳离子进行定性定量分析,方法简单可靠、结果准确。     

《资本论》经济伦理视阈下低碳经济发展研究

该文从《资本论》的人道观、自由观、正义论角度出发,对中国建立低碳经济制度进行分析,认为《资本论》对高碳经济的正义审视仍未过时,对建设中国低碳经济的制度保障也不乏现实的启示性。     

复写纸复写笔迹变化的原因探析

与正常书写条件下形成的笔迹相比，复写纸复写笔迹的特征变化性更大，鉴定难度更高。本文阐述了从书写承受物、书写工具、书写时间、书写人心理等方面进行深入研究，探析复写纸复写笔迹变化的几点主要原因，为全面掌握复写纸复写笔迹变化的规律和准确鉴定该类笔迹打下了坚实的理论基础。     

与碳排放交易有关的犯罪行为及其防范措施

碳市场属于新兴市场,呈现碎片化特征。碳排放交易标的为法律虚拟物,不需要实物交割,交易相对复杂。碳排放交易和其他金融交易一样,由于涉及资金巨大、法律不完善、监管不严密和透明度欠缺等原因,极易滋生犯罪。与碳排放交易有关的犯罪行为主要为诈骗、逃税、洗钱和网络盗窃等。应该加强各碳排放交易市场间的合作与沟通,共同监管和惩治碳排放交易所涉犯罪行为。     

Tenax GR吸附解析技术在火场汽油残留物提取检验中的应用研究

目的针对火灾现场常规提取检验方法操作复杂、容易导致汽油残留物有效成分丢失等问题,研究建立采用Tenax GR吸附解析技术简便、高效提取检验汽油残留物的方法。方法将Tenax GR吸附管放入相关检材中,密封后在60℃烘箱中加热1h,经热脱附仪解析后使用气质联用仪分析。结果Tenax GR吸附解析技术可以检验汽油残留物中特征组分,主要包括甲苯、二甲基苯、三甲基苯、四甲基苯、萘、甲基萘及茚满类化合物。该技术的检测限为0.25pL/mL,同时放入6根吸附管做稳定性实验,其相对标准偏差(RSD)为2.43%。该技术进行7、15、30、60、90d等不同阶段的保存实验,其相对偏差分别为6.3%、14.4%、8.7%、18.3%、11.6%。结论该技术操作方便、灵敏度高、稳定性好,适用于火灾现场中汽油残留物的提取检验。     

Climate Change Policies, Energy Security and Carbon Dependency Trade-offs for the European Union in the Longer Term

Energy policy in the European Union (EU) faces two major challenges. The first challenge is posed by EUs commitment to reduce greenhouse gas emissions to the atmosphere in the context of the international agreement on climate change. The second challenge is to keep ensuring European security of energy supply, while its dependency on external sources of energy is projected to increase. In this paper, two long-term alternative climate change policy scenarios for Europe are examined. In the first scenario, EU reduces carbon dioxide emissions by domestic measures; in the second scenario EU maximizes cooperation with the countries of the former Soviet Union (FSU). Impacts on carbon flows between the EU and FSU and on the external energy dependency of the EU are assessed with an applied general equilibrium model, GTAP-E, whose set of energy commodities is expanded with combustible biomass as a renewable and carbon-neutral energy commodity. The results show that there is a trade-off between economic efficiency, energy security and carbon dependency for the EU. The FSU would unambiguously prefer cooperation.     

Lead-free primer residues: a qualitative characterization of Winchester WinClean, Remington/UMC LeadLess, Federal BallistiClean, and Speer Lawman CleanFire handgun ammunition

The elemental composition and postfiring residues of several "lead-free" or "nontoxic" centerfire handgun ammunition types currently available to the general public were examined. Offerings from Winchester, Remington/UMC, Federal and Speer were obtained from retail sources in both .45 ACP and 9 mm when possible. A total of 112 postfiring residue samples (SEM pins) were collected at varying distances from the muzzle, at two distances from target and from the shooter's hands. An additional 20 samples were collected by direct ignition of primers. Qualitative determinations were carried out using scanning electron microscopy (SEM)/electron dispersive spectrometry (EDS) analysis. All types tested contained aluminum (Al), silicon (Si), copper (Cu), and zinc (Zn). Most contain traces of sulfur and calcium. Winchester WinClean and Remington LeadLess contained potassium as the principle ingredient. Federal BallistClean contained barium, while Speer Lawman CleanFire contained strontium. In the main, these compared favorably with manufacturers' MSDS publications and patents granted. The characterizations undertaken here will be of use to the forensic electron microscopist as these formulations gain popularity.     

Biotic Carbon Sequestration and the Kyoto Protocol: The Construction of Global Knowledge by the Intergovernmental Panel on Climate Change

This paper explores the dynamics of the production of global knowledge by an international knowledge organization, in this case the Intergovernmental Panel on Climate Change. Based on previous notions of international boundary organizations, the idea of international knowledge organizations emphasizes the knowledge generation function of such organizations rather than their convening function. Using the case of controversial Kyoto Protocol biotic carbon sequestration policies, I argue that boundary work and uncertainty management are the essential dynamics in the successful construction of global knowledge by international knowledge organizations. This uncertainty management occurs in a manner broadly, although not completely, in conformance with the institutional preferences of powerful policy actors. Global knowledge can legitimate and help refine global policies, but the process of its construction must be iterative and transparent if it is to be credible for global environmental governance over the long-term.
