1带交-直装置的自励异步发电机稳态分析显示文摘一、前言本文论述自励异步发电机(SEIG)的稳态分析。对一台作为独立电源的SEIG的运行,电机的端电压及频率取决负载及原动机的转速。可采用交-直-交变换方案控制SEIG的电压及频率。这种交-直-交线路使用一只固定电容器及可变换向电容器。固定电容器与电机永久联接,以维持额定转速、空载时电机的端电压;可变电容器则是当负载在一定范围内波动时,不断切换。S.Singh M.Jain 杨宝龙 文晟忠 1992中小型电机1992,19,3:1
2Development of creative problem solvingbased framework for site planning in hill areas显示文摘The growing urbanization of hill towns results in an increasing demand for infrastructural facilities.Infrastructural facilities are generally planned without considering the effects of the surroundings as well as their effects on the sensitive ecosystem of hill areas.Site planning decisions are taken on the basis of judgment and experience of planners in the absence of a rational and quantitative framework for ensuring the sustainable development of hill areas.This scenario generates the need for an efficient site planning framework.Site planning is a creative problem solving(CPS)process.Hence,in the current study,the CPSbased framework is developed as follows.First,existing CPS-based frameworks for planning and designing are reviewed.Second,the framework is developed for site planning in hill areas.Third,the developed framework is validated through planning infrastructural facilities of an institutional campus on a site located in hill areas.The major strength of the developed framework includes three cycles,namely,understand,process,and implement.Site planning decisions are taken through the generation of alternate scenarios and their subsequent evaluation on the basis of impact on the sensitive ecosystem of hill areas.N.Kapoor V.K.Bansal M.Jain 2020Frontiers of Architectural Research2020,9,2:0
3间接液化的生物工艺显示文摘0 引言由来自煤的煤气和甲醇生物合成液体燃料的方法对于发展高选择性、高效率的煤液化工艺具有很大的潜力。大量的诸如一氧化碳、氢气、二氧化碳和甲醇之类的碳一原料能够从煤或天然气等矿物燃料中得到。这种间接液化技术的焦点集中在两个阶段的厌氧生物转化上。第一阶段是通过适应于一氧化碳的甲基营养的丁酸杆菌(Butyribacterium methylotro--phicum)把合成气体(CO,H_2/CO_2)转化成为挥发性脂肪酸。第二阶段是通过乙酰丁基型梭状芽孢杆菌(Clostridium acetobutylicum)把脂肪酸生物转化成为可燃的丙酮、丁醇和乙醇溶剂。酸性基因细菌能将一氧化碳或甲醇直接转化成为乙酸酯(acetate)和丁酸酯(butyrate)而不消耗合成气中的氢。所需要的氢来自于水而无须进行转换反应。R.Datta M.Jain 赵玉兰 1989煤炭综合利用译丛1989,,4:0
