Chinese renaissance can not only be understood as a catalyst for globalization, but it does also enlarge the global village by opening new economic, political, diplomatic, intellectual, and artistic horizons. Our government pays more attention to publicize and preserve traditional culture. Therefore, it becomes an urgent task about how to do research and mining, preserve fine traditional Chinese culture, and enhance the international cultural communication. Rhymed opera proverb as an important part of Chinese opera culture mirrors the ideology and culture in China. The opera proverb is responsible for both inheriting the tradition and developing the ancient art. The biggest challenge is translation which is carrier of culture. Through good translation, we will gain a better understanding of the quintessence of our tradition and of the living embodiment of China and Chinese culture. This paper is intended to study opera proverb translation from the viewpoint of ＂intertextuality＂. The author believes that translation is a type of transforming activity intertextualized with language, text, and culture. Intertextuality theory is applied to investigate the process of translation. Intertextuality will be of great help to the translation of opera proverbs, which means not only to explore and transfer the literal meaning of the source text, but also to interpret and expound the cultural meaning. Only if a translation is reliable and makes sense of traditional culture can our culture be known and appreciated by the world.展开更多

Kung fu Panda, a blockbuster by Dream works, sets off a new upsurge of the Chinese style. It not only gives a chance for the audiences in western countries to enjoy the traditional Chinese culture, but also for the Chinese to enjoy this visual feast. This article will illustrate the implicit and explicit Chinese elements in Kung fu Panda, in hope of finding out the extensive use of Chinese elements in today＇s Hollywood movies. According to the collection of media data concluded, the film production team undertook detailed investigation and studies in the traditional Chinese culture so that today＇s Hollywood movies can successfully interpret Chinese elements. Thus, the international cultural communications are found hiding behind the widely used of Chinese elements. With the analysis of this article, Chinese reader can know further about how important the diffusion of Chinese traditional culture is. Thereby, it can remind Chinese people of the responsibility to carry on and broadcast the splendid traditional Chinese culture.展开更多

The study has shown that when both AC and DC systems operated in parallel, this system has higher transmission capability than operated separately, thus it satisfies stability criterion after the project put into operation.展开更多
