"气韵"是中国传统艺术审美中独特的命题。论文从这一美学范畴显示的人类情感深度具有的意境之美切入,探讨"气韵生动"在民族声乐演唱中的内涵和歌曲处理方法,从而总结出"气韵生动"的演唱之意境美,反映了中国传统文化对全宇宙、生命的关注,要求歌唱要蕴含丰富的宇宙感、人生感,还要努力超越自我,灵动于空。 相似文献

Study on oxidizing cellulose to 2.3-dialdehyde cellulose by sodium periodate (NalO4) was carried out. The effects of reaction conditions such as pH of solution, temperature, oxidant concentration, oxidation time. the particle size of 2,3-dialdehyde cellulose and alkali treatment temperature on the dialdehyde concentration ot cellulose were investigated in detail, The results show that the aldehyde group content was created while reaction temperature and alkali treatment temperature increased. The most principal factors affecting the aldehyde group content of 2,3-dialdehyde cellulose were found out and the best oxidation conditions were as follows: the pH was 2. the reaction temperature was 45℃. the mass ratio of cellulose to NalO4 was 1/2, the reaction time was 4 h, the alkali treatment temperature was 70℃ and smaller particle size was 0.80 mm. 相似文献

为了探究自定量化目标策略在排球教学中的最优效果,采用实验、数理统计等研究方法,通过性别和技术难度2项指标,将自定量化目标策略下的学生成绩分别与其他2组目标策略下的学生成绩进行比较.结果表明:采用自定量化目标策略后,男生成绩好于女生,且学习技术难度越大,男生优势越明显;女生适合采用指定量化目标策略;男女生白定目标的风格不同,男生更勇于挑战. 相似文献
