絮凝法处理纸浆漂白废水的研究

研究了无机絮凝剂ＰＡＣ，ＰＳＡ，ＰＥＳ，ＭｇＣｌ２，ＣａＯ及其与有机高分子絮凝剂ＣＧＡ复全使用对两种不同工艺漂白废水的混凝处理特性，结果表明，水质１ＣＯＤｃｒ，ＡＯＸ去除率分别为６３．２％，４５．３％，水质２ＣＯＤｃｒ，ＡＯＸ去除率达７３．１￥％，５３．４％。化钙与碳酸钠具有相同的降解ＡＯＸ能力，硫离子在中性ｐＨ条件下可显著提高ＡＯＸ的去除率。

克山病病区低硒粮喂养的豚鼠红细胞内Na~+浓度变化的研究

豚鼠分别喂以克山病病区粮(低硒)和非病区粮(硒含量正常),借助合成的D_Y(PPP)_2~(-7)位移试剂用XL-400NMR谱仪直接测试完整红细胞内Na~+的NMR谱,并定量计算细胞内Na~+浓度,发现低硒的病区粮饲养的豚鼠红细胞内Na~+浓度显著高于正常组;病区粮喂养的豚鼠红细胞在老化条件下细胞溶血比非病区严重。

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.
