MITI projects on recycling

MITI has actively done R&D on industrial technology for waste and reclamation and so there are many research items from small scale to large scale. However, Ecofactory and researches on recycling of metallic materials are introduced here. Ecofactory was proposed by the Mechanical Engineering Laboratory and is now at the stage of the Leading Research, a new research scheme in AISt. Researches on recycling of metallic materials are being done with subsidy. Those researches should contribute to both the preservatin of the global environment and effective recycling of waste materials.Abbreviations AIST Agency of Industrial Science and Technology - MITI Ministry of International Trade and Industry - NEDO New Energy and Industrial Technology Development Organization     

宁夏黄河经济及其非均衡协调发展战略

宁夏黄河经济应是宁夏区域经济,发展宁夏黄河经济必须立足于宁夏黄河资源的开发。广义而言,黄河资源基本上是宁夏全部的国土资源.其开发模式应由过去的单一开发、浅层开发向综合开发、深度开发转换。同时要注重以水利建设为突破口,以水利、农业两大基础产业为重点,煤—电—高耗能系列开发、灌溉—农业—轻工业系列开发、教育—人才—信息系列开发三大主导方向并行。发展宁夏黄河经济,应选择具有优势的部门和地区实行重点开发,使其优先增长,以此辐射带动整个区域的发展。     

抽油机技术经济指标的模糊综合评价

针对我国抽油机评价过于笼统、模糊，缺乏全面性和综合性以及评价方法可操作性差的现状，提出了抽油机技术经济指标模糊综合评价方法。在确定抽油机评价指标的层次体系基础上，建立了抽油机技术经济指标模糊综合评价的数学模型，并以某厂CYJ10－3－53HB型抽油机为实例，对其运动和动力性能作了综合评价。这种模糊综合评价方法全面考虑各种性能指标以及它们对抽油机总体性能影响的不同程度，能得到较合理的评价结果，而且有较强的可操作性。     

Recovery of monomers and fillers from high-temperature-vulcanized silicone rubbers—combined effects of solvent, base and fillers

The depolymerization of high-temperature-vulcanized (HTV) silicone rubbers containing filler silica and alumina into cyclosiloxane monomers and spontaneous recovery of fillers were studied. First, HTV silicone rubber was treated with different types of solvents in the presence of KOH to find that a triad mixture of diethylamine, methanol and hexane was appropriate not only to dissolve the silicone rubber to a suspension but also to separate fillers completely by filtration. The filtrate was distilled to remove solvent first and then give pure cyclosiloxane monomers in 76–84% yields. Second, the rubbers were treated with other types of triad mixture of solvents and bases, e.g. tetramethylammonium hydroxide, hexane and diethylamine. After filtration, residue was again treated with the amine and hexane to recover clean fillers in 83–93% yields. Cyclosiloxane monomers were also obtained from the combined filtrates in 67–78% yields.     

浅析当前环境下国有资产的现状和管理对策

改革开放使中国经济实现了持续高速的发展。然而,随着改革的不断深入,国有资产面临着在新经济环境下的角色转换,在此过程中由于各种原因每年有数百亿元的国有资产流失,所以,国有资产的保值增值成为现阶段乃至将来一段时间我国政府的重大经济课题。本文对国有资产的历史和现状进行了分析并从多角度提出了一些管理方面的看法。
