希腊美学思想的集大成者亚里士多德创立了延续两千余年而未衰的诗学理论,他承认了文艺的客观真实性,建立了艺术有机整体以及和谐的概念,并肯定了文艺的社会功用。然而其诗学理论随着时间的流逝和社会的发展逐渐显现出其特定的局限性。本文结合韩国著名悲剧电影《假面》,从摹仿说和悲剧论(包括悲剧的定义、悲剧的有机结构、过失说和净化说)两大角度试探讨亚里士多德诗学理论在当代的适应性与局限性。 相似文献

Bulk polymerization of styrene was carried out in the presence of a reversible addition-fragmentation chain transfer (RAFT) of benzyl dithiobenzoate (BDB). The comparison between reaction systems with and without BDB indicates that there is significant retardation in the reaction rate when BDB is used. The molecular weight of styrene polymer prepared with BDB shows linear relationship with the conversion of monomer, polydispersity is as narrow as 1.2, and no gel effects are observed during the polymerization with BDB, which are characteristics of a living radical polymerization. It has been found that the concentrations of BDB and azobis(isobutyronitrile) (AIBN) have opposite effects on the polymerization kinetics, and the AIBN dominates. 相似文献

Like many river basins in China, water resources in the Fudong Pai River are almost fully allocated. This paper seeks to assess and evaluate water resource problems using water evaluation and planning (WEAP) model via its application to Hengshui Basin of Fudong Pai River. This model allows the simulation and analysis of various water allocation scenarios and, above all, scenarios of users' behavior. Water demand management is one of the options discussed in detail. Simulations are proposed for diverse climatic situations from dry years to normal years and results are discussed. Within the limits of data availability, it appears that most water users are not able to meet all their requirements from the river, and that even the ecological reserve will not be fully met during certain years. But the adoption of water demand management procedures offers opportunities for remedying this situation during normal hydrological years. However, it appears that demand management alone will not suffice during dry years. Nevertheless, the ease of use of the model and its user-friendly interfaces make it particularly useful for discussions and dialogue on water resources management among stakeholders. 相似文献

关于大学生心理健康调查的报告 总被引：10，自引：0，他引：10
大学生的心理健康,不仅是大学生当前正常心理生活的必要保证,而且也是他们日后自我完善个性不可或缺的条件,同时它对大学生自身生理健康亦有至关重要的影响。现代医学把人类所患的疾病分成心身病、身心病、神经病和精神病四大类,说明身、心二因素对于一个人的健康与否有着相依共存的联系,这是人们在探讨自身科学过程中对主体认识深化的标志。那么大学生的心理健康状况到底是怎样的呢?由于传统观念和技术手段等诸多原因,我们国家对大学生心理健康问题的研究在很长历史时期内是一片空白。不过令人欣喜的是,最近几年我们国内正有不少高校开始对大学生的心理健康情况进行调查研究,并且开展心理咨询和心理矫治等业务活动。但是,关于师范院校师范专业大学心理健康状况如何?目前还没有见到详实材料的报道。 相似文献

As a raw material,kaolin was modified to prepare a high-performance ammonium ion-exchange material.According to cation-exchange capacity (CEC) measurement,the prepared ammonium ion-exchange material has an ammonium ion-exchange capacity greater than 75mg/g and can be used to remove ammonia nitrogen in water treatment.A pharmaceutical extruder-rounder was used to study the effects of granulation process.Polyethylene glycol6000 (PEG-6000) was used as the pore-forming agent and calcining temperature of 650℃ was used as the optimal condition.NMR data indicate that 27 Al is mainly converted from hexa-coordinated Al to tetra-coordinated Al during the modification.Compared with 29 Si in the original kaolin,29 Si in the modified kaolin does not have an obvious change.A comparison of the data with Langmuir and Freundlich isotherm models shows a good correlation.The Freundlich model describes the process more accurately,and the adsorption process of ammonia nitrogen in water with the ammonium ion-exchange material closely matches the pseudo-second-order reaction. 相似文献
