| 1 | Computer Aided Simulation on Precision Cold Forging of Universal Joint Cross显示文摘The 3D FEM numerical simulation on multi-action precision cold forging technology of universal joint cross and differential spider is done in this article using DEFORM Software, a commercial computer aided engineering software specializing in forming and heat treatment simulation technology, and suitable for cold, warm and hot forging process. The material flow properties, the dynamic variation of stress and strain in the process of deformation and the load-stroke curve have also been achieved. A good consistency is exhibited between simulation results and practical data. Based on the DEFORM simulation results, the optimized procedure has been found for forging a universal joint cross. What should be emphasized here is that a better understanding of practical forging characters and the environmental factors can greatly improve the simulation accuracy thus make the simulation results more reliable. | H.

| 2 | Estimation of methane and nitrous oxide emissions from biomass waste in China:A case study in Hebei Province显示文摘Crop residue,animal manure and MSW are selected as representative biomass waste.Greenhouse gas emissions from treatment and disposal process of biomass waste in Hebei province are estimated for the period from 2002 to 2007,using the methodologies recommended by the Intergovernmental Panel on Climate Change.Greenhouse gas emission was about 10 Mt CO2-equivalent annually.About 6% of greenhouse gas emission came from open burning of crop residue,74% from management system of animal manure,and 20% from MSW disposal.Among all the greenhouse gas sources,landfill is the most concentrated one,and has significant potential of emission reduction. | LUO YuXiang1,WANG Wei1,WAN Xiao2,DENG Zhou2 & ZHU CuiPing2 1 Department of Environmental Science and Engineering,Tsinghua University,Beijing 10084,China 2 J&K China Cleaning Energy Technology Company Limited,Beijing 100085,China | 2010 | Science China(Technological Sciences)2010，53，1： | 6 |
| 3 | LABORATORY MEASUREMENTS IN SINE-GENERATED MEANDERING CHANNELS显示文摘The patterns (In flow plan) of rough turbulent steady flows in sine-generated meandering streams are investigated experimentally. The flow cross-section is rectangular, the flow width is uniform, the channel bed is flat; the plan shape is sine-generated. In contrast to previous works, where the computed flow patterns were of the same character, irrespective of the sinuosity of the channel, it is found, on the basis of present experiments, that every different Plan geometry of a meandering flow has its own flow picture. In the case of 'small' sinuosity, the flow convectively accelerates at the inner bank between the crossover-and apexsections; if, however, the sinuosity is 'large', the now convectively decelerates in the same region. The convergence-divergence areas (in flow Plan) of the present flows are in coincidence with the location of erosion-deposition zones in meandering streams, confirming that the convective behaviour of the vertically-averaged flow alone is sufficient to induce the bed and bank deformation. | A.

| 12 | Biogas recovery from microwave heated sludge by anaerobic digestion显示文摘Biogas generated from sewage sludge,livestock waste,and food waste by anaerobic digestion is a valuable renewable energy resource.However,conventional anaerobic digestion is not an efficient process.A long hydraulic retention time and low biogas recovery rate hinder the applications of those resources.An effective pretreatment method to destroy sludge microbial cells has been one of the major concerns regarding improvement of the biogas production.This article focuses on the effects of microwave heating on sludge anaerobic digestion.Volatile suspended solid(VSS) and chemical organic demand solubilization of heated sludge were investigated.Microwave heating was found to be a rapid and efficient process for releasing organic substrates from sludge.The increase of organic dissolution ratio was not obvious when holding time was over 5 min with microwave heating.The effect of the VSS solubilization was primarily dependent on heating temperature.The highest value of VSS dissolving ratio,36.4%,was obtained at 170°C for 30 min.The COD dissolving ratio was about 25% at 170°C.Total organic carbon of treated sludge liquor was 1.98 and 2.73 g/L at 150°C and 170°C for 5 min,respectively.A biochemical methane potential(BMP) test of excess sludge and a mixture of primary and excess sludge demonstrated an increase in biogas production.The total biogas from microwave treated mixture sludge increased by 12.9% to 20.2% over control after 30 days of digestion.Biogas production was 11.1% to 25.9% higher for excess sludge than for untreated sludge.The VS removal ratios of mixture sludge and excess sludge were 12% and 11% higher,respectively,compared to the untreated sludge. | QIAO Wei1,WANG Wei2,ZHU CuiPing3 & ZHANG ZhongZhi1 1 College of Chemical Science and Engineering,China University of Petroleum,Beijing 102249,China 2 Department of Environmental Science and Engineering,Tsinghua University,Beijing 10084,China 3 J & K China Cleaning Energy Technology Co.Ltd.,Beijing 100085,China | 2010 | Science China(Technological Sciences)2010，53，1： | 1 |
