对应用多媒体于中学音乐教学的反思     

高重阳 《宁夏教育》2009,(12):38-38

现代教育信息技术的多元化、多样性,具有突破时空局限、扩大容量的特点,它使音乐语言描述的内容由相对单一静态转变为动态的审美对象,并加快美的信息传递速度,加大美的信息容量,使学生更为直观地接受美的熏陶。现在有许多音乐教师注意开发这些课程资源,他们利用现代多媒体技术,根据自身的知识结构、专业特长,充分发挥自身智慧,有效地提高中学音乐课的质量。  相似文献   

Investigation on the factors influencing the thickness distribution of superplastic-formed components   总被引：1，自引：0，他引：1

In the superplastic sheet forming process, the uniformity of the sheet's final thickness distribution is vital for ensuring the good mechanical quality of the formed components. The influences of the component shape and the contact friction on the final thickness distribution were investigated in this work by using finite element method on a series of axisymmetric models. It was concluded that shape optimization and friction elimination are required to get uniform thickness distribution, and eventually to improve the mechanical quality of the formed components. The constitutive equation of the Ti-6Al-4V superplastic material was also determined on the basis of experimental data.  相似文献
