图腾文化与“S”形的表意构造——甘肃秦安羊皮鼓舞表演队形的文化含义

秦安羊皮鼓舞是广泛流传于甘肃天水一带,以羊皮鼓为基本道具的一种民间祭礼歌舞活动。由于其特殊的地理位置,因而较为纯粹地保留了原有的形态特征。本文以该活动中舞蹈表演场图所展示的"S"形为研究对象,试图解释其与当地民众的信仰及图腾文化的渊源。

Influence of Different Lubricants on Deformation Behaviour of IN 718 Alloy in Hot Compression Process

The influence of different lubricants on the deformation behaviour of IN 718 alloy was studied. The results show that, with the improvement of lubrication condition, the deformation of the alloy tends to be homogeneous, and the resistance of deformation decreases. Consequently, FR 2 glass lubricant is considered to be an ideal choice when the relationship between stress and strain of IN 718 alloy is measured by means of hot compression experiment.

论汉代建鼓形制与图像配置的汉文化意蕴

在汉画中,建鼓无论在车马出行、乐舞百戏,抑或在神话仙境和鬼怪传奇等图中,无不体现出它所承载的汉代社会生活与审美旨意的密切联系。本文认为:汉画图绘的建鼓形制以及图像配置,均将天、地、人、神、鬼融入同一个场域,勾画出一幅沉雄强悍、诡异升仙的幻想世界,承载着汉代艺术最深刻的文化意蕴、艺术风格和哲学思想。
