中、俄、蒙三国的油气合作

中国处于石油资源相对贫乏的东亚西太平洋区域,总体石油资源不足;俄罗斯东西伯利亚和远东地区的石油和天然气储量丰富,蒙古石油矿藏集中在中蒙两国边界地区,这为中、俄、蒙的油气合作提供了可能,并且从蒙古直接穿过进入中国的中俄石油管道是最近、最安全的线路。从未来发展的趋势看,中国可积极利用俄蒙的资源投资与合作,参与输气、输油管道的建设,拓宽和夯实中俄油气合作的经济基础。     

战后初期日本解决能源供应危机的政策设计

煤炭、石油、电力等能源的供应危机是战后日本经济复兴中最大的“瓶颈约束”。日本为确保经济发展所需的能源动力,选择了具有“国家管制”和“行政计划”特征的能源配置框架;确立了优先加强能源“量”的增产和供应而非“利润”和“效益”的政策目标;运用了行政约束、法律强制、精神动员等多元化的政策工具。日本舒缓和规避能源“瓶颈约束”的政策构想源于统制经济思想。     

论中国能源法的生态化

能源法是我国近年来发展最为迅速的立法领域之一。在生态文明观的指导下，不断涌现的能源法呈现出生态化的特征。我国能源法的生态化主要表现为新指导思想的出现、立法结构的生态化、能源法律制度的进步等。     

铁铬合金菜刀遗留金属颗粒的成分评价方法

目的检测铁铬合金菜刀遗留的金属颗粒成分,并建立可行的评价指标及方法。方法使用滤纸擦蹭菜刀制作金属遗留微小颗粒样本,应用扫描电镜-X射线能谱仪(scanning electron microscopy and energy dispersive X-ray spectrometer,SEM-EDX)的GSR颗粒分析功能检测遗留金属颗粒成分,计算遗留金属颗粒中铁、铬相对含量比。结果铁铬合金菜刀遗留金属颗粒内所含铁、铬相对含量比,在大部分菜刀间差异有统计学意义(P0.05)。结论使用GSR颗粒分析功能量化检测铁铬合金菜刀遗留金属颗粒内铁、铬相对含量比,为此类致伤工具的认定建立可行的评价方法。     

Fabrication of compound nonwoven materials for soft body armor

The primary objective of body armor research is the development of low-cost, lightweight, wearable garments that effectively resist ballistic impact. This study introduces a material intended to reduce nonpenetration trauma by absorbing energy from ballistic impacts. Layers of web were made by low-melting point polyester (LMPET) on unaligned fibers of high-strength polyamide 6 (HSPA6). A compound nonwoven fabric was made by laying high-strength Vectran filaments between two layers of HSPA6-LMPET web. The new fabric underwent needle punching and thermal bonding to form a composite sandwich structure. The new fabric was subjected to a falling weight impact test and a ballistic impact test. The results indicated that the material with the new design reduced maximum indentation depth by 8%. Furthermore, soft body armor made from the material with the new design would cost less to produce and would weigh 22.5% less than conventional soft body armor.     

论应对气候变化背景下能源开发利用与环境保护相结合原则

能源开发利用产生的环境问题日益严重,直接威胁到人民的生活质量和发展,能源开发利用与环境保护相结合原则是指在开发利用能源时,必须减少污染排放,加强环境保护,它也称清洁开发利用能源原则。在应对气候变化背景下,能源立法的基本原则应该树立低碳能源和低碳经济理念,坚持能源开发利用与环境保护相结合原则。     

能源变革中的首都西南区域经济发展与战略选择

石油、天然气等非再生能源供给约束对经济发展的制约,使人类开始探索第三次能源变革。伴随每次能源结构变革是现代产业发展的巨大变化,后者又进一步推动经济社会发展。北京致力于世界城市建设,其经济社会发展要形成国际影响力与控制力,其顺应能源发展趋势的合理产业布局至关重要,而首都西南区域目前正处于传统产业退出、接续产业尚未形成时期,如果利用后发优势,建立国家战略性新兴能源产业基地,将可能实现区域经济的跨越式发展。     

Gunshot residue in Chicago police vehicles and facilities: an empirical study

Suspects in shooting investigations in Chicago are routinely transported in department vehicles and detained in department facilities prior to gunshot residue (GSR) evidence collection. The GSR test results are used to associate the suspect with primary exposure to GSR. The potential for these vehicles and facilities being sources of secondary GSR contamination needed to be determined. A total of 201 samples were collected from randomly selected vehicles and detention facilities. The sampling collected trace materials from surfaces that suspects' hands may contact during the arrest process. These samples were examined for the presence of GSR particles using scanning electron microscopy. Upon completion of the automated analysis, those particles that met an initial GSR screening criterion were relocated and reanalyzed. The locations where GSR particles were recovered allowed us to make recommendations to the Chicago Police Department with regard to transporting and detaining these suspects. The low number of GSR particles recovered suggests that the potential for secondary contamination, although present, is relatively low.     

中俄两国经贸关系发展现状及其广阔前景

中俄两国是重要的经济贸易伙伴。在经受了2008年全球金融和经济危机冲击后,中俄两国经贸关系全面恢复和迅速发展。在中俄政府总理定期会晤制度框架下,建立了两国经济合作对话与协商机制。近年来,中俄贸易规模不断扩大,能源领域的合作日益深化,相互投资不断增加,地区间的经济贸易关系全面发展。全面提升贸易质量,扩大贸易规模,增加相互投资,深化能源合作,推动地区间和边境地区经贸合作,加强经济现代化领域合作,将成为中俄经贸关系发展的重要方向。     

加强中国与东盟能源安全合作的国际法思考

中国与东盟的能源安全合作已从现实和制度层面展开,但是仍然存在能源产品出口受到限制、能源运输通道安全受到威胁、南海问题向国际化方向发展等问题,应当注重国际法规范在保障中国与东盟能源安全合作中的作用,利用联合国条约体系、WTO协议和CAFTA协议,充分认识ECT和NAFTA协定的借鉴意义。
