Idols and B-boys stages are fun, touching, and fantastic. Today, South Korean students are excited and enthusiastic about their colorful dance moves. The study is about creative educational methods that use K-pop music videos to learn the proverbs and old words that our ancestors learned to keep in mind and teach. K-pop lyrics are a rich reflection of the experiences of life and the world in which people are living today. Accordingly, this study can present new teaching and learning method examples that are used in class related to the old language associated with K-pop lyrics and can also introduce interesting class materials.展开更多
以10μm硅胶为基质,异甘草素为配体,采用液相连续反应法及中间体法依次合成了异甘草素键合硅胶固定相ISLSP-Ⅰ和ISLSP-Ⅱ。采用FTIR及SEM对合成的固定相进行表征。将ISLSP-Ⅰ固定相填充于50 mm×10 mm i.d. 1号色谱柱中,将ISLSP-Ⅱ...以10μm硅胶为基质,异甘草素为配体,采用液相连续反应法及中间体法依次合成了异甘草素键合硅胶固定相ISLSP-Ⅰ和ISLSP-Ⅱ。采用FTIR及SEM对合成的固定相进行表征。将ISLSP-Ⅰ固定相填充于50 mm×10 mm i.d. 1号色谱柱中,将ISLSP-Ⅱ固定相填充于30 mm×10 mm i.d. 2号色谱柱中,系统评价了两种方法合成的固定相的色谱性能。结果表明:两根色谱柱的柱效及峰型均较好,大流速下测试组分的保留主要决定于传质阻力。在甲醇-水体系下,2号色谱柱表现出明显的反相色谱分离机制。合成的固定相稳定性良好,使用6个月后,测试组分在两根色谱柱上的保留时间相对偏差不超过0.9%。2号色谱柱对多组分标准样品及中药提取物均具有良好的分离能力。展开更多
