近10年中国三大经济区太阳总辐射特征及其与O3、PM2.5的关系

采用中国地面气象观测站网2007~2016年的辐射日值数据集和中国空气质量在线监测平台2014~2016年逐日观测数据,分析了京津冀、长三角和珠三角近10a太阳总辐射年际和季节变化,近3a臭氧日最大8h平均（O_{3_8h_max}）和细颗粒物（PM_2.5）的污染过程频次变化,通过不同因子及其不同强度等级的分型统计,探讨PM_2.5、O_{3_8h_max}与太阳总辐射的关系.结果表明：京津冀近10a太阳总辐射显著上升,京津冀春季和珠三角夏季太阳总辐射显著上升.三大经济区PM_2.5污染过程年频次均呈现逐年递减,且从北到南递减;O₃污染过程年频次时间上呈现先减后增,空间上京津冀多于长三角和珠三角.三大经济区O_{3_8h_max}与太阳总辐射相关系数均在0.71以上,有较强的正相关;而PM_2.5与太阳总辐射的相关性具有区域差异性.三大经济区不同季节不同太阳总辐射下O_{3_8h_max}与PM_2.5的相关关系差异显著,其中京津冀春夏秋三季O_{3_8h_max}与PM_2.5在强太阳总辐射下有较好的正相关,冬季则存在一定的负相关;长三角四季两者相关性均较弱;珠三角夏季两者正相关最为显著;不同PM_2.5浓度下O_{3_8h_max}与太阳总辐射的线性拟合效果较好,体现出较强的正相关关系,各经济区拟合曲线的倾向率均随PM_2.5升高而增大.PM_2.5>75μg/m³时拟合优度均达到最大.     

铜合金实验室试验与实海挂片结果的比较与分析

目的比较实验室试验结果与实海挂片结果对B10和H62两种铜合金腐蚀性能评价的异同之处。方法采用线性极化、电化学阻抗、显微形貌观察等,比较两种铜合金在实验室模拟海水中的的腐蚀速率、点蚀倾向,结合反应机理、腐蚀形貌、环境等外部因素,分析导致实验室与实海环境下出现差异的原因。结果除榆林海域外,实海挂片与实验室结果都表明,B10试样的平均腐蚀速率小于H62。B10和H62两种铜合金随温度升高腐蚀速率增大,在实验室和实海情况下表现出一致性,且平均腐蚀速率都随浸泡时间的延长而降低。结论在实海环境中,温度不是影响点蚀的主要因素,微生物等其他环境因素会对点蚀产生较大影响。

A pilot project to detect and forecast harmful algal blooms in the northern Gulf of Mexico

More timely access to data and information on the initiation, evolution and effects of harmful algal blooms can reduce adverse impacts on valued natural resources and human health. To achieve this in the northern Gulf of Mexico, a pilot project was initiated to develop a user-driven, end-to-end (measurements to applications) observing system. A key strategy of the project is to coordinate existing state, federal and academic programs at an unprecedented level of collaboration and partnership. Resource managers charged with protection of public health and aquatic resources require immediate notice of algal events and a forecast of when, where and what adverse effects will likely occur. Further, managers require integrated analyses and interpretations, rather than raw data, to make effective decisions. Consequently, a functional observing system must collect and transform diverse measurements into usable forecasts. Data needed to support development of forecasts will include such properties as sea surface temperature, winds, currents and waves; precipitation and freshwater flows with related discharges of sediment and nutrients; salinity, dissolved oxygen, and chlorophyll concentrations (in vivo fluorescence); and remotely-sensed spatial images of sea surface chlorophyll concentrations. These data will be provided via a mixture of discrete and autonomous in situ sensing with near real-time data telemetry, and remote sensing from space (SeaWiFS), aircraft (hyperspectral imagery) or land (high-frequency radar). With calibration across these platforms, the project will ultimately provide a 4-dimensional visualization of harmful algae events in a time frame suitable to resource managers.

A Metamodeling Approach for Integrated Assessment of Air Quality Policies

A method is proposed to build integrated models (also called Metamodels) aimed at quantifying the economic efficiency of air quality policies. This Metamodeling approach is based on the coupling of two complementary models, that operate at different scales in space and time, and which represent the economic and the physical and chemical processes, respectively. The joint consideration of the physico-chemical and techno-economic structure of the pollution control problems permits a comprehensive evaluation of air pollution abatement strategies. The motivating pollution control problems include urban-regional air quality management through efficient energy and traffic control policies. A pilot study, exploiting data collected in the Geneva canton (Switzerland), is used to demonstrate the potential of the approach.

煤中有害元素对环境和人体健康影响的评价参数

煤中有害元素对环境和人体健康影响的较为全面的评价体系一直未建立，环保部门也缺乏系统性评价参数对电厂等在煤煤过程中有害元素排向大气的释放量进行监测估算。本文在查阅大量资料（主要为外文）的基础上，认为评价煤中有害元素对环境和人体健康影响的参数应该包括以下方面的数据C、H、O、N、无机硫，有机硫，有害微量元素的含量，分布规律，赋存状态，迁移转化行为（在燃煤过程中），洁净能力，淋滤力，矿物质，有机化学特征，煤炭学特征，并对煤中有害元素的污染方法进行探讨，如果上述各参数的数据被全面提供，并据此数据作针对性的抑制措施，煤中有害元素对环境和人体健康危害影响必将降低到最小。
