论元代“水浒戏”之李逵形象     

荆清珍 《阿坝师范高等专科学校学报》2007,24(4):100-102

元代之前的李逵形象描写太不突出,只是个符号,元杂剧时代大量的水浒戏诞生,李逵形象迅速丰富起来,成为莽细兼备,粗雅合一的喜剧性绿林英雄,个性多样,甚至相互矛盾。李逵作为人物形象不是线性发展的人物,而是随着时代感而突兀变化的人物形象,是带有时代烙印的角色,元杂剧的李逵是"元代的李逵"。  相似文献   

Mathematical model for electroosmotic dewatering of activated sludge     

于晓艳  张书廷  郑磊  刘勇  徐晖 《天津大学学报(英文版)》2011,17(1):39-44

The mechanical dewatering of activated sludge is difficult due to its high compressibility, which can be improved by electroosmosis. In electroosmosis, direct electric field is applied to sludge cake. Based on the conductivity modes of different sludge beds, a model is presented in which sludge cake consists of two series parts in the circuit: a dewatered bed and an undewatered one. The dewatered bed called solid conductor is mainly made up of immovable water and sludge particles. The undewatered bed includes movable water and solid conductor, which are connected in parallel in the circuit. The model describes the variation of water content with time and electric power consumption as a function of water content in sludge cake, and interprets the reason for the variation of electroosmotic dewatering rate. Comparison with the experimental data for electroosmotic dewatering under constant voltage supports the validity of the model.  相似文献

Natural water purification and water management by artificial groundwater recharge     

Balke KD  Zhu Y 《Journal of Zhejiang University. Science. B》2008,9(3):221-226

Worldwide, several regions suffer from water scarcity and contamination. The infiltration and subsurface storage of rain and fiver water can reduce water stress. Artificial groundwater recharge, possibly combined with bank filtration, plant puri- fication and/or the use of subsurface dams and artificial aquifers, is especially advantageous in areas where layers of gravel and sand exist below the earth's surface. Artificial infiltration of surface water into the uppermost aquifer has qualitative and quanti-tative advantages. The contamination of infiltrated fiver water will be reduced by natural attenuation. Clay minerals, iron hy-droxide and humic matter as well as microorganisms located in the subsurface have high decontamination capacities. By this, a final water treatment, if necessary, becomes much easier and cheaper. The quantitative effect concerns the seasonally changing fiver discharge that influences the possibility of water extraction for drinking water purposes. Such changes can be equalised by seasonally adapted infiltration/extraction of water in/out of the aquifer according to the fiver discharge and the water need. This method enables a continuous water supply over the whole year. Generally, artificially recharged groundwater is better protected against pollution than surface water, and the delimitation of water protection zones makes it even more save.  相似文献

The impact of NiO on microstructure and electrical property of solid oxide fuel cell anode     

Li Y  Luo ZY  Yu CJ  Luo D  Xu ZA  Cen KF 《Journal of Zhejiang University. Science. B》2005,6(11):1124-1129

INTRODUCTION The solid oxide fuel cell (SOFC) has attracted much attention as a promising source of electrical power generation because of its high efficiency in converting chemical energy to electrical power. De- velopment of SOFC with operating temperature of less than 800 °C has been extensively studied. SOFC has the potential to have the cost of its materials, cell fabrication, and corrosion of its stack components dramatically reduced. Gadolinia-doped ceria with the chemical fo…  相似文献
