Based on the modeling method, patterns, ware series, buried characters of the bronzes and the archaeological culture at the lower-reaches of Xiang River,the author comes to a conclusion that the exception of "local" bronzes can reflect the true history more accurately than that of "mixed" bronzes.展开更多

Using the real part of shear modulus, the polymer can be classified into three types： glassy film, glassy-rubbery film and rubbery film, Experimental results show that the attenuation response is in better consistence with the simulation than in Martin＇s theory, but the velocity response does not accord with the calculation exactly. Maybe it is influenced by the experimental methods and environment. In addition, simulations of gas sorption for polymer films are performed. As for glassy film, the SAW sensor response increases with increasing fihn thickness, and the relationship between the sensor response and the concentration of gas is pretty linear, while as for glassy-rubbery flint and rubbery film, the relationship between the sensor sensitivity anti concentration of gas is very complicated. The ultimately calculated results indicate that the relationship between the sensor response and frequency is not always linear due to the viscoelastic prooerties of the polymer.展开更多

The large prestige of this repertoire, in fact, often goes along with a distorted perception of a number of very important features that tend to be underrated, discarded or not taken in the due consideration by the public. Only recently has musicology paid attention to the danger of this stereotyped vision of classical music, regarded as a sort of temple of seriousness, or as a kingdom where an alleged harmony reigns unchallenged. The topic of this article is precisely the other side of classical music, which also turns out to be a world torn by conflict and filled with artistic tension, where things do not always add up. To support this standpoint, a number of very well-known pieces are considered, paying attention to their less reassuring features. Thus, compositions that seemed to be familiar show a complex and disturbing expressive texture. As a result, a widespread listening attitude finds reasonable grounds for being changed： Instead of languidly leaning back into the armchair with closed eyes, the unbiased listener is requested by the music itself to keep its eyes wide open.展开更多
