论“中国美学”的学科特质

狭义的“中国美学”是指中国古代美学思想及其在当代的研究和继承发展。它是中国人数千年来审美实践和思想概括的产物。中国古代只是没有“美学”这一学科名称,但是早已有了丰富的美学思想。中国美学不仅包含在美学思想中,更感性地存留在体现审美意识的器物和历代文学艺术作品中。审美意识是中国美学的源头活水。中国美学元范畴围绕一个核心不断衍生,形成了独特的以意象为中心的范畴系统。佛学思想的融入有力地开拓了中国美学的发展。中国美学重体验、重视主体的直觉思维等特点,将自然规律与社会法则贯通起来,体现了生命意识。中国古代美学思想中有着潜在的体系,需要我们借鉴西方,面向当代的审美实践进行理论建构,以彰显中国美学的独特性。中国美学通过与西方美学的对话融合,走向现代,走向世界,最终成为多元一体的世界美学的有机组成部分。

Chinese Journal of Chemical Engineering 2010年第6期18卷 905-909页

作者： LIU Jingming SUN Dongdong LIU Hui NIE Yingbin zhu zhirong School of Chemical Engineering Northeast Dianli University Jilin 132012 China Department of Chemistry Tongji University Shanghai 200092 China Department of Chemical Engineering Jilin Vocational College of Industry and Technology Jilin 132013 China

Biodegradation parameters and kinetic characteristics for pre-treating waste strains of Klebsiella pneu-moniae were studied in laboratory scale with an insulated reactor by an innovative technique,autothermal thermo-philic aerobic digestion(ATAD) . Based on an Arrhenius-type equation,an empirical model was developed to corre-late the removal of total suspended solid(TSS) with the initial TSS concentration,influent reaction temperature,aeration rate and stirring rate. The reaction temperatures of the ATAD system could be raised from the ambient temperatures of 25 °C to a maximum temperature of 65 °C. The exponentials for the initial TSS concentration,aeration rate and stirring rate were 1.579,-0.8175 and-0.6549,respectively,and the apparent activation energy was 6.8774 kJ·mol-1. The correlation coefficient for the pre-exponential factor was 0.9223. The TSS removal effi-ciency predicted by the model was validated with an actual test,showing a maximum relative deviation of 10.79%. The new model has a good practicability.
