Not only do they show a tendency toward the weakening of grand narrative and sense of responsibility and the strengthening of individual aspirations, they also show different aesthetic traits in terms of narrative form. Some advocate a realist style, while others pursue modernist techniques or are enamored of fragmentary details. At the same time, each generation projects its own aesthetic ideas. From the viewpoint of cultural anthropology, this kind Of generation gap essentially implies the effect of the latent protocols of different historical-cultural contexts and memories of growing up on the human spirit. Although the generation gap is an expression of a plural cultural scene, the question of how to strengthen intellectual interaction between different generations of writers and effectively overcome the limitations of each generation remains an important aspect of the promotion of the healthy development of modern Chinese literature.展开更多

Many studies are carried out within the instantaneous-exchange approximation, which ignores all but the zero-frequency component of the boson propagator and fermion self-energy function. We extend these studies by taking the retardation effects into consideration. In this paper, we get the explicit frequency n and momentum p dependence of the fermion self-energy function and identify the critical temperature for different fermion flavors in the chiral limit. Also, the phase diagram for spontaneous symmetry breaking in the theory is presented in Tc-Nf space. The results show that the chiral condensate is just one-tenth of the scale of previous results, and the chiral symmetry is restored at a smaller critical temperature.展开更多
