岷江上游崩塌滑坡分布规律研究

岷江为长江—级支流，上游长３３０ｋｍ，自１９８６年以来，发生崩塌滑坡２００余处，体积约２．１亿ｍ￣３。作者研究了岷江上游崩塌滑坡的分布规律。采用统计指标法，将岷江上游分为三种不同的崩塌滑坡分布密度区：①ＵＸＳ．高密度区；②ＭＸＳ，中密度区；③ＬＸＳ＿３低密度区。     

南宁城市大气污染对人体健康的危害及治理对策

南宁市大气属煤烟型污染 ,大气的主要污染物为SO2 、NOx、TSP、降尘 ,虽然随着环境管理和污染治理工作的加强 ,污染物浓度逐年下降 ,但是工业区大气污染仍然较重。污染物流行病学调查显示 :工业区癌症和呼吸系统疾病死亡率均高于全市平均水平 2倍左右 ,城区又高于郊区 2倍 ,大气污染综合指数与呼吸内科门诊就诊人数呈正相关。用邓聚龙的灰色系统理论分析得知污染物对癌症和呼吸系统疾病死亡率有关联 ,关联度从大到小排序为 :TSP >降尘 >SO2 >NOx ,最后提出了大气污染治理的对策。

对低影响开发与海绵城市的再认识

海绵城市建设是在继承我国古代先贤智慧和参考国外经验,系统总结我国雨洪管理领域长期研究和实践经验的基础上,结合我国城市水系统实际问题提出的城市发展方式,其核心是构建基于绿灰结合的现代城市雨洪控制系统,通过"渗、滞、蓄、净、用、排"综合措施,实现"治涝"与"治黑"等多重目标。低影响开发是海绵城市建设的重要指导思想,也是海绵城市核心技术体系的重要组成部分。正确认识低影响开发与海绵城市的内涵与联系,对于进一步在全国范围内落实低影响开发建设模式,科学推进海绵城市建设具有重要意义。     

Density functional theory (DFT) studies of vanadium-titanium based selective catalytic reduction (SCR) catalysts

Based on density functional theory (DFT) and basic structure models, the chemical reactions on the surface of vanadium-titanium based selective catalytic reduction (SCR) denitrification catalysts were summarized. Reasonable structural models (non-periodic and periodic structural models) are the basis of density functional calculations. A periodic structure model was more appropriate to represent the catalyst surface, and its theoretical calculation results were more comparable with the experimental results than a non-periodic model. It is generally believed that the SCR mechanism where NH₃ and NO react to produce N₂ and H₂O follows an Eley-Rideal type mechanism. NH₂NO was found to be an important intermediate in the SCR reaction, with multiple production routes. Simultaneously, the effects of H₂O, SO₂ and metal on SCR catalysts were also summarized.
