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

The addition of TATA can lead to the formation ofβ-crystal PP. With the increase in TATA concentration the degree of crystallinity for β-crystal PP increased significantly, and that for a-crystal PP decreased, which indicated that TATA effectively induced the formation of β-crystal PP. WAXD also revealed the existence of β-crystal PP after the introduction of TATA into PP. PP containing TATA crystallized at a temperature range of 5-10℃ higher than that of pure PP, and the half-crystallization time （t1/2） and Avrami exponent （n） of PP at the same cooling rate were decreased by the addition of TATA, indicating that TATA influenced the crystallization rate and crystallization growth mode of PP. The rate constant of crystallization of PP containing TATA （Zc） was larger than that of pure PP, which further indicated that the crystallization of PP was accelerated by the addition of TATA.展开更多
