在磁场中活性炭吸附有机物的研究

将磁化技术引入吸附过程中，考察了磁场处理对活性炭吸附苯、硝基苯、苯甲酸、氯苯和苯酚的影响．结果表明，预磁处理能使非极性物质苯和极性较小的氯苯、苯酚在活性炭上的吸附容量减小，而使极性较大的苯甲酸和有NO2基团的硝基苯的吸附容量增大．增大磁场强度能加强苯和苯甲酸的磁处理效果。     

云南省经济增长与能源消耗的计量模型研究

根据云南省1985~2003年能源消耗的统计数据以及人均GDP统计数据,分析人均GDP与能源消耗之间的相关关系,选取相关性较好的能耗指标(煤炭消耗量、石油消耗量、天然气消耗量、电力消耗量)建立两者之间的计量模型。并在此基础上分析能源消耗与人均GDP增长的关系。经研究发现,云南省经济增长与能源消耗呈类似于EKC的倒U型曲线,且曲线尚未到达转折点,能源消耗量随着经济增长将持续增长。有必要采取有利措施倡导“循环经济”、“绿色GDP”等使曲线走势向良性方向发展。     

V2O5-WO3/TiO2脱硝催化剂的制备及其性能

对选择性催化还原脱硝用催化剂V2O5-WO3/TiO2的制备工艺进行了实验研究.采用溶胶-凝胶法制得TiO2凝胶,对凝胶进行不同条件下的干燥和煅烧处理,然后通过浸渍法在TiO2上依次负载WO3和V2O5,最终得到V2O5-WO3/TiO2催化剂.结果表明,TiO2凝胶的处理温度对催化剂结构和脱除NO的性能有一定的影响,TiO2凝胶干燥温度为105 ℃时制得的催化剂活性较高,在实验条件下NO脱除率最高可达98.3%.     

A Simulation of Temporal and Spatial Variations in Carbon at Landscape Level: A Case Study for Lake Abitibi Model Forest in Ontario,Canada

Using a case study of the Lake Abitibi Model Forest (LAMF), this study aims to assess the temporal and spatial variability in carbon storage during 1990–2000, and to present a comprehensive estimation of the carbon budget for LAMF's ecosystems. As well, it provided the information needed by local forest managers to develop ecological and carbon-based indicators and monitor the sustainability of forest ecosystems. Temporal and spatial carbon dynamics were simulated at the landscape level using ecosystem model TRIPLEX1.0 and Geographical Information System (GIS). The simulated net primary productivity (NPP) and carbon storage in forest biomass and soil were compared with field data and results from other studies for Canada's boreal forests. The results show that simulated NPP ranged from 3.26 to 3.34 tC ha⁻¹ yr⁻¹ in the 1990s and was consistent with the range measured during the Boreal Ecosystem-Atmosphere Studies (BOREAS) in central Canada. Modeled NPP was also compared with the estimation from remote sensing data. The density of total above-and belowground biomass was 125.3, 111.8, and 106.5 tC ha⁻¹ for black spruce, trembling aspen, and jack pine in the LAMF ecosystem, respectively. The total carbon density of forested land was estimated at 154.4 tC ha⁻¹ with the proportion of 4:6 for total biomass and soil. The analysis of net carbon balance of ecosystem suggested that the LAMF forest ecosystem was acting as a carbon sink with an allowable harvest in the 1990s.

有机气溶胶的来源与形成研究现状

介绍了有机气溶胶来源与形成的研究现状,从有机气溶胶的化学组成特征、一次有机气溶胶的来源和二次有机气溶胶的形成机制论述其研究进展.一次有机气溶胶主要来源于烹调油烟、机动车排放、生物质燃烧、工业或民用燃油锅炉释放出的有机物,还有道路扬尘、沥青、刹车尘、轮胎屑、室外香烟烟雾、以及高等植物蜡、细菌活动和草本植物等.大气中的半挥发性有机物可通过物理和化学吸附形成二次有机气溶胶,一些挥发性有机物可通过气相化学反应转化为低挥发性的物质并形成二次有机气溶胶,其主要前体物是芳香族化合物,如苯、甲苯、二甲苯,以及烯烃、烷烃、环烷烃、萜烯和生物排放的非饱和氧化物.     

Effect of free-air CO2 enrichment on nematode communities in a Chinese farmland ecosystem

At a rice-wheat rotational free-air CO2 enrichment(FACE) platform, the effect of elevated atmospheric CO2 on soil nematode communities in a farmland ecosystem was studied. Wheat plots were exposed to elevated atmospheric CO2 (ambient 370 μl/L 200 μl/L).32 families and 40 genera of nematode were observed in soil suspensions during the study period. Under FACE treatment, the numbers of total nematodes, bacterivores and fungivores exhibited an increasing trend. Because of the seasonal variation of soil temperature and moisture, the effect of elevated atmospheric CO2 on soil nematodes was only observed under favorable conditions. The response of nematode communities to elevated atmospheric CO2 may indicate the change of soil food web.
