Wang Feng is a winner walking on the ideological balance beam. After deconstructing Cui Jian's grand narrative mode and strong critical feature, his works have been endowed with heavy critical color and reflection value by a grassroots band named "Xuriyanggang". Besides, Wang Feng's works have eliminated the distinction between the official and folk feature, elegance and worldly feature, as well as elite and mass. To a large extent, they have defined the rock music in contemporary China, and pushed the Chinese rock to the mainstream market. Consequently, the Chinese rock has been gradually developed into multiple and compound culture modes.展开更多

The images of Elvis Presley, who earned the sobriquet "King of Rock" early in his career, and that of B. B. King, the exemplar extraordinaire of the Blues, are ubiquitous in the city of Memphis, which may be regarded as a metonym for the Blues and Rock 'n Roll. The byline for the city of Memphis is, "Home of the Blues, Birthplace of Rock 'n Roll", and this fact announces itself to the visitor as soon as he/she enters the arrivals concourse of the Memphis International Airport. As one proceeds towards the baggage claims area, the images which saturate the walkway create an aura that is redolent of the city's vibrant Rock 'n Roll era. Drawing on Foucault's notion of heterotopias, as well as Jakobson's work on metonymy, this paper explores the hybrid musical spatiality of the city of Memphis and its environs, as well as its iconic status in the evolution of Rock 'n Roll which was engendered by the Blues.展开更多

Also, the paper through CUI's works tries to inquire the questions of how the ideal of socialism transforms after the fail of the revolution and how the disillusion connects the country's pursuit of the western modernization in music. Moreover, the paper asks how and by which CUI's songs associate themselves to the social transformation and in what way they root in the "socialistic personality" shaped by the socialist revolution since 1950s.展开更多

文摘Our differential and grading toothed roll crusher blends the advantages of a toothed roll crusher and a jaw crusher and possesses characteristics of great crushing,high breaking efficiency,multi-sieving and has,for the moment,made up for the short- comings of the toothed roll crusher.The moving jaw of the crusher is a crank-rocker mechanism.For optimizing the dynamic per- formance and improving the cracking capability of the crusher,a mathematical model was established to optimize the transmission angleγand to minimize the travel characteristic value m of the moving jaw.Genetic algorithm is used to optimize the crusher crank-rocker mechanism for multi-object design and an optimum result is obtained.According to the implementation,it is shown that the performance of the crusher and the cracking capability of the moving jaw have been improved.
