Reevaluation of the density dependence of nucleon radius and mass in the global color symmetry model of QCD

With the global color symmetry model (GCM) at finite chemical potential, the density dependence of the bag constant, the total energy and the radius of a nucleon in nuclear matter is investigated. A relation between the nuclear matter density and the chemical potential with the action of QCD being taken into account is obtained. A maximal nuclear matter density for the existence of the bag with three quarks confined within is given. The calculated results indicate that, before the maximal density is reached, the bag constant and the total energy of a nucleon decrease, and the radius of a nucleon increases slowly, with the increasing of the nuclear matter density. As the maximal nuclear matter density is reached, the mass of the nucleon vanishes and the radius becomes infinite suddenly. It manifests that a phase transition from nucleons to quarks takes place.Comment: 18 pages, 3 figure

On Translation of Advertisements from the Perspective of Culture

Each language contains elements which are derived from its culture, such as idioms, proverbs, and other fixed expressions. Translation is not only an inter-lingual transfer, but also a cross-cultural communication. Along with the development of the economy and science, globalization is a more increasingly obvious phenomenon. There is is closer and closer relationship between countries. So the intercultural advertisements are becoming common. The inter-cultural advertisements transmission is to communicate with the consumers from different regions, different nations, different countries and different societies. And the politics, economy and cultural situations in these areas are different from those in their own nations. And in all of these differences, the difference between cultures is the one that has the greatest and the most direct influence on the transmission of advertisements. If one wants to do well in advertisements translation, one must have a good knowledge about the culture whose language is his target language. And in the transmission of advertisements, knowing what one should do is as important as knowing what one should not do. In this paper, the author takes into consideration the cultural factors that affect the translation of the intercultural advertisements and then offer some suggested strategies when doing the translation.Key words: culture difference; intercultural advertisements; translation strategie

The Exploration and Analysis on the Reform of Classroom Teaching Mode for Translation Subject

Regardless of certain learning effects, the mechanical practice mode in traditional translation teaching is, to some extent, stimulated by behaviorism, and widely divergent from our learner-oriented as well as interaction-focused teaching ideal. To train well-rounded translation professionals with the spirit of innovation and exploration as well, it is necessary for us to establish both interactive and collaborative learning atmosphere, encourage self-examination in translation theory and translation skill practice also, and achieve the initial effects in real teaching practice by relying on associated theories of education, psychology, and linguistics, etc, combining the features of translation subject, and truly implementing the student-oriented, task-featured, and modern educational technology-based principle.
