大风速电收尘技术研究

把流体力学、电动力学和静电学有机综合应用于电收尘器（ＥＰ）研究和设计上，是对现在电收尘器机理的一次变革。根据电场、流场理论，应用计算机进行设计的新型高效Ω－２Ｃ型集尘极板，仅一层Ω－２Ｃ型集尘极板的收尘效率就可达到８０％左右。把Ω－２Ｃ型集尘极板改成迎风排列，此时烟气风速成为收集烟尘的动力，而不是破坏力，大幅度提高烟尘趋进速度，大大减小ＥＰ体积、重量，成倍降低ＥＰ的造价，有利捕集粉尘，降低因振打引起的二次飞扬。     

Deep Geological CO2 Storage: Principles Reviewed, and Prospecting for Bio-energy Disposal Sites

The principles of hydrocarbon exploration and production provide well-established and tested principles and technologies to investigate storage of fluids in the subsurface. CO₂ can be stored in the subsurface using settings of: (A) thick permeable coal seams; (B) depleted oil and gas fields; (C) saline aquifers of regional extent, with an overlying seal. The North Sea Sleipner project shows that CO₂ can be injected into the pore space of deep geological aquifers deeper than 800 m at 1 Mt/yr, using established technology. Suitable sediment sequences of saline aquifers exist in all hydrocarbon-producing areas, are volumetrically much larger than exploited oil and gas fields, and hold the potential to easily store all worldwide CO₂ emissions until 2050. Geological principles are established to assess entire continents for candidate sites of CO₂ storage. This shows that opportunity may be widespread, but needs more specific local investigations. Onshore sub-Saharan Africa is considered the most problematic region – but even here there are potentially viable sediment sequences. No demonstration projects currently exist for CO₂ capture and storage using small-scale onshore facilities. A simple estimate, assuming CO₂ value of $20 per ton, suggests that single boreholes onshore may be viable over 20 years with supply rates of 100,000 ton CO₂ per year. In principle, atmospheric CO₂ could be captured by cultivated biomass, and co-fired in existing power stations. Or energy crops could be grown, CO₂ to be used, and stored deep below ground, in a country distant from an original fossil-fuel CO₂ emission site.

植物对环境污染的适应代价

生物长期暴露在低浓度污染环境中会作自我调整来适应环境.适应继续, 其代价即可检测到.一般来讲,适应代价由进化代价和生态代价组成.进化代价主要集中在污染程度上,也就是说,适应于目前环境的植物群落会失去适应其他环境的能力,进化敏捷性减弱.尽管有一些学者并不赞成,但有大量科学数据支持这一观点.生态代价指的是生物适应寒冷、炎热、干燥和其他压力的能力降低,这些都是基于trade-offs理论产生的.

火山断陷盆地的边缘成矿论

火山断陷盆地是构造-岩浆-地热体系的最活跃场所。大中型热液矿床往往赋存于盆地边缘。高渗透构造破碎带、基底和火山盖层建造的相应组合、多阶段次火山岩的侵入、配套的水文地质环境构成了盆边热源、矿源、水源、矿质沉淀空间的最佳匹配条件。因此．盆地边缘作为矿床预测和靶区优选的显著目标值得找矿者的高度重视。     

Carbon Offset Potentials of Four Alternative Forest Management Strategies in Canada: A Simulation Study

Using an Integrated TerrestrialEcosystem C-budget model (InTEC), we simulated thecarbon (C) offset potentials of four alternativeforest management strategies in Canada: afforestation,reforestation, nitrogen (N) fertilization, andsubstitution of fossil fuel with wood, under differentclimatic and disturbance scenarios. C offset potentialis defined as additional C uptake by forest ecosystemsor reduced fossil C emissions when a strategy isimplemented to the theoretical maximum possibleextent. The simulations provided the followingestimated gains from management: (1) Afforesting allthe estimated 7.2 Mha of marginal agricultural landand urban areas in 1999 would create an average Coffset potential of 8 Tg C y^-1 during 1999–2100,at a cost of 3.4 Tg fossil C emission in 1999. (2)Prompt reforestation of all forest lands disturbed inthe previous year during 1999–2100 would produce anaverage C offset potential of 57 Tg C y^-1 forthis period, at a cost of 1.33 Tg C y^-1. (3)Application of N fertilization (at the low rate of 5kg N ha^-1 y^-1) to the 125 Mha ofsemi-mature forest during 1999–2100 would create anaverage C offset of 58 Tg C y^-1 for this period,at a cost of 0.24 Tg C y^-1. (4) Increasingforest harvesting by 20% above current average ratesduring 1999–2100, and using the extra wood products tosubstitute for fossil energy would reduce averageemissions by 11 Tg C y^-1, at a cost of 0.54 TgC y^-1. If implemented to the maximum extent, thecombined C offset potential of all four strategieswould be 2–7 times the GHG emission reductionsprojected for the National Action Plan for ClimateChange (NAPCC) initiatives during 2000–2020, and anorder of magnitude larger than the projected increasein C uptake by Canada's agricultural soils due toimproved agricultural practices during 2000–2010.
