论美声唱法的"靠前"与"靠后"     

严露 《贵阳师范高等专科学校学报》2005,(3):71-73

美声唱法分为“靠前”与“靠后”两大学派。“靠前唱法”强调声音的明亮、靠前、打在硬口盖上．集中于面孔前部（鼻腔、面罩）部位；“靠后唱法”则强调声音的厚度、力度、喉腔开度大，音的立体柱状感及音的落点感受较深。它们有机结和点在于声音的明亮集中、圆润、丰满，两派是互补的辩证统一的。  相似文献   

Direct and indirect measures of writing for nonlearning disabled and learning disabled college students     

Mary Morris-Friehe  Janice Leuenberger 《Reading and writing》1992,4(3):281-296

Direct and indirect measures were used to compare the written language abilities of three groups of college students: two with learning disabilities and one without learning disabilities. Main effects were found for group, but not gender. Differences between nonlearning disabled students (NLD) and those with learning disabilities (LD) in writing were evident on both types of measures. Performance by LD students with disabilities in an area other than writing differed depending on the type of measure and often was no different from either of the other two groups. The combined use of direct and indirect measures appeared most effective for examining the complexities of writing produced by all groups.  相似文献   

Facile and efficient one-pot synthesis of 2-arylbenzoxazoles using hydrogen tetrachloroaurate as catalyst under oxygen atmosphere     

Yun-kui Liu  Da-jie Mao  Shao-jie Lou  Jian-qiang Qian  Zhen-yuan Xu 《Journal of Zhejiang University. Science. B》2009,10(6):472-478

In this paper, we presented a novel method for the facile and efficient one-pot synthesis of 2-arylbenzoxazoles, which oxygen atmosphere with anhydrous tetrahydrofuran (THF) as solvent or in solvent-free condition. The results show that this method could bring excellent yields as high as 96%. THF was proven to be the best choice among several solvents screened and the reaction was tolerated with a variety of aromatic aldehydes possessing electron-donating or withdrawing groups. The advantages of the present method lie in catalytic process using economic and environmentally benign dioxygen as oxidant.  相似文献
