After 1952, the Central Government gave special support to the preservation and promotion of ethnic languages. Newspapers, magazines and publishing houses mushroomed in Xinjiang, Inner Mongolia, Yunnan, Guangxi, Guizhou, Tibet, Qinghai, Gansu, Yanbian and other places where ethnic groups where living in compact communities. In this situation, journals on Tibetan studies developed in two stages : First Stage: 1950-1980. During this period, all the newspapers and journals in China carried news on economic and social development in Tibet. However, at the provincial level the only newspapers were the Qinqhai Tibetan Paper, Tibet Daily (Tibetan and Chinese editions) and Qinghai Daily, and at the regional level, among the very few newspapers available were the Gannan News, Aba News and Garze News. Magazines published during the period were equally sparse. They included Qinghai Lake, Zamqar, Qinghai Ethnic institute News, Hanhaichao, Snow Lotus, Tibet Science and T6chnology, Tibet Literary and Art, Tibetan Medicine, Tibet Ethnic institute News and Chinese Yaks. Second stage: 1981-1998. This period witnessed dramatic economic and social development. In this encouraging situation, the number of newspapers increased to more than 180 kinds in the Tibetan areas. Tibetan studies expanded in scope, covering politics, history, literature, arts, agriculture, livestock breeding, education, medicine, folklore, tourism, archaeology, finance, science and technology, and geology. The following is a brief introduction to the magazines published after the peaceful liberation of Tibet in 1951.展开更多

[Method] Based on the analysis of particulate matter online observation data and meteorological data during the corresponding period in Chinese environmental science college, Hysplit Back trace model and Numerical weather prediction graphs, and combined with the different analytical methods on meteorological flow fields, a typical process of particles in Beijing during early 2008 Olympic Games was studied. [Result] The results indicated that during the ascent stage of PM2.5 concentration, the PM showed gradually aging phenomena; the process controlled by large scale synoptic system mainly. And the weak wind and the high humidity were not in favor of dispersion; the prolonged southerly air mass to bring the pollutant of Hebei, Taijin and Shandong to Beijing; mixing height and temperature curve took the importance role to the pollution. [Conclusion] The study provided theoretical basis for the discussion on factors influencing the production and elimination of particles in the air pollution process.展开更多
