N/Ce doped graphene supported Pt nanoparticles for the catalytic oxidation of formaldehyde at room temperature

Pt catalysts with nitrogen-doped graphene oxide (GO) as support and CeO₂ as promoter were prepared by impregnation method,and their catalytic oxidation of formaldehyde (HCHO) at room temperature was tested.The Pt-CeO₂/N-rGO (reduced GO) with a mass fraction of 0.7% Pt and 0.8%CeO₂ exhibited an excellent catalytic performance with the 100% conversion of HCHO at room temperature.Physicochemical characterization demonstrated that nitrogendoping greatly increased the...     

Environmental impact assessment in the association of southeast Asian Nations

The Association of Southeast Asian Nations has agreed that environmental protection and sustainable use of natural resources are essential for sound economic development. The Environmental Impact Assessment is viewed as an important management tool and an ASEAN Experts Group on the Environment has been working for several years on a model especially adapted to the region and also on case studies of the implementation of EIA. Progress so far has been frustratingly slow due to misunderstanding, a lack of ecological data, inadequate trained manpower and institutional shortcomings for compliance. The author advocates collaboration on an ASEAN model for performing EIA as a means of accelerating acceptance and implementation. The concept of Adaptive Environmental Assessment and Management is proposed as a prototype.     

室内准稳态压力火灾烟气沉降模型的改进和实验验证

对室内火灾及烟气的研究给消防工程领域带来了诸多益处,如疏散时间预测、基于性能化的设计分析等。Zukoski (Fireand Materials,1978,2(2): 54-62)在室内火灾烟气运动的开创性研究给出了基于质量和能量平衡的理论方法,为后续研究奠定了基础。然而实验发现,由于忽略热损失偏差,模型对近壁面火源的火灾烟气沉降时间的预测缺乏准确度。本文通过空间重构的方法消除房间长宽比因素造成的热损失偏差,引入两个参数进行表征,以完善该模型。完善后的模型预测烟气沉降时间与实验吻合度非常好,验证了该方法的有效性。在计算分析基础上,将两个参数对模型的影响作了评估,发现其一对模型预测结果的影响远大于另一参数。火源大小确定后,烟气充满房间的时间范围可确定,火源功率越大,时间范围越小。

The siting puzzle: Balancing economic and environmental gains and losses

Traditional approaches to the siting of potentially hazardous but regionally necessary facilities are often ineffective and lead to drawn-out legal disputes ultimately satisfactory to none of the parties. Research at MIT over the last decade has indicated five factors that may solve the siting puzzle. Application of these principles do not guarantee that a decision will not be disputed but may enhance the possibility of a wise and durable agreement.

基于MRIO模型的中国对外贸易隐含大气污染转移研究

采用全球多区域投入产出（MRIO）模型耦合二氧化硫（SO₂）、氮氧化物（NO_x）、可吸入颗粒物（PM₁₀）、非甲烷挥发性颗粒物（NMVOC）排放清单,定量分析了2012年中国与其他国家贸易过程中隐含的大气污染排放转移.结果显示,中国是隐含SO₂、NO_x、PM₁₀排放的输出地和隐含NMVOC排放的输入地.欧盟、东亚和美国购买我国商品（如电力燃气和水供应业、重工业和矿采选业）导致的出口隐含大气污染排放量占比约为70%.中国在消耗撒哈拉以南非洲地区、中东&北非、东亚、东南亚和欧盟进口商品过程中,导致上述地区排放NMVOC为3.1×10⁶t,约占我国进口隐含NMVOC排放的69.2%.为了减轻我国对外贸易中承担的环境负担,本文从加强重污染产业管控、发展绿色经济、推进全球绿色供给链等方面提出相关政策建议.     

城市公交车厢内噪声监测与分析

主要对城市公交车厢内的噪声进行监测分析,用等效连续A声级和室内噪声评价指标对监测数据进行分析,评估车厢内的声音品质。结果表明,单纯用A声级不能准确反映公交车厢内的噪声污染状况,用室内噪声标准NCB曲线分析的结果与乘客的主观感受相关性良好,建议用A声级和NCB标准曲线综合考虑制定公交车厢内的噪声标准。
