2006年联合国教科文组织首次颁发"孔子教育奖",这表明伟大教育思想家孔子至今仍为世人所敬仰,他那博大精深的教育思想对中国和世界教育的发展都产生了极其深远的影响。要好好地继承这一民族文化瑰宝,就应重温孔子,研读《论语》,观摩孔子的教学场景,感悟其中的教育智慧,增长教书育人的才智。 相似文献

Water is the most abundant compound inherently existing in bio-oils. Thus understanding the role of water within bio-oils upgrading process is essential for future engineering scale-up design. In this study, furfural was chosen as bio-oils model compound, and the catalytic hydrogenation of furfural over commercial 5%, Ru/C catalyst was firstly investigated in a series of gradient variable water/ethanol mixture solvents. Water had a significant effect on the distribution of product yields. The dominant reaction pathways varied with the water contents in the water/ethanol mixture solvents. Typically, when ethanol was used as the solvent, the main products were obtained by the hydrogenation of carbonyl group or furan ring. When pure water was used as the solvent, the rearrangement reaction of furfural to cyclopentanone should be selectively promoted theoretically. However, serious polymerization and resinification were observed herein in catalytic hydrogenation system of pure water. The catalyst surface was modified by the water-insoluble polymers, and consequently, a relative low yield of cyclopentanone was obtained. A plausible multiple competitive reaction mechanism between polymerization reaction and the hydrogenation of furfural was suggested in this study. Characterizations(TG,FT-IR,SEM)were employed to analyze and explain our experiments. 相似文献

高师公共教育学课程资源的现状与开发 总被引：1，自引：0，他引：1
张成武 《太原大学教育学院学报》2007,25(3):26-29
丰富优质的课程资源是实现课程目标的基本条件,目前高等师范院校公共教育学课程资源在教材内容、教学方式和教学时空方面的缺陷都非常明显。开发课程资源要有开放意识、目标意识和责任意识,开发实践中,要紧扣教学大纲,充分利用现代媒体信息和教育技术,为学习者提供丰富的教育场景,并重视个体经验交流。 相似文献
