Their love and care for the people have featured their governance and won extensive acclamation in China and the world. On March 18, the top legislature of China, the National People’s Congress, elected Hu Jintao President of State and Wen Jiabao Premier of the State Council. The new leadership of China was formed in the applause of NPC deputies. Right after the new leadership took its office, a tough challenge confronted them as a series of disasters broke out suddenly. In spring, the severe acute respiratory syndrome (SARS) rapidly swept over half of the country within a month; in summer, an unprecedented flood hit South China; then earthquakes erupted in Inner Mongolia, Xinjiang and Yunnan in succession. In front of these disasters, the new Chinese leaders remained calm and confident, with resolute measures they successfully brought the situation under control and tid-展开更多

These studies disproved Orientalist assumptions of a unique ＂Chinese way of war＂ or a strategic culture that avoided aggressive confrontation. Scholars also challenge the assumption that Confucian immobility led to a clash of civilizations and decisive defeat in the Opium Wars, First Sino-Japanese War, and Boxer War of 1900. In fact, Qing officials were quick and successful in creating a new military regime. New military histories of the warlords, the Sino-Japanese Wars, and the Chinese Civil War show that developing new types of warfare was central in creating the new nation. All these wars split the country into factions that were supported by outside powers： they were internationalized civil wars. The article also asks how the choice of terms, labels, and categories shapes interpretations and political messages.展开更多

However, how modem mass human migration during the CNY holiday affects the urban heat island （UHI） is still un- known. Here, the authors investigate the role of modem human migration for the UHI effects during the CNY holiday for the period of 1992-2006 in Harbin City, Northeast China. The results show that during the CNY week, the UHI effects expressed as daily mean, maxi- mum, and minimum temperature differences between urban and rural stations averaged over the period of 1992-2006 are 0.65℃ （43%）, 0.31℃ （48%）, and 1.14℃ （71%） lower than during the background period （four weeks before and four weeks after the CNY week）, re- spectively. Our findings identify previously unknown impacts of modem mass human migration on the UHI effects based on a case study in Harbin City.展开更多

Firework displays resulted in a burst of SO2, coarse mode, and accumulation mode （100-500 nm） particles. Through single particle mass spectrometry analysis, five different types of particles （fireworks-metal, ash, dust, organic carbon-sulfate （OC-sulfate）, biomass burning） with different size distributions were identified as primary emissions from firework displays. The fireworks-related particles accounted for more than 70% of the total analyzed particles during severe firework detonations. The formation of secondary particulate sulfate and nitrate during firework events was investigated on single particle level. An increase of sulfite peak （80SO3） followed by an increase of sulfate peaks （97HSO7＋96SO7） in the mass spectra during firework displays indicated the aqueous uptake and oxidation of SO2 on particles. High concentration of gaseous SO2, high relative humidity and high particle loading likely promoted SO2 oxidation. Secondary nitrate formed through gas-phase oxidation of NO2 to nitric acid, followed by the condensation into particles as ammonium nitrate. This study shows that under worm, humid conditions, both primary and secondary aerosols contribute to the particulate air pollution during firework displays.展开更多

Although mostly associated with dogs, the rabies virus（RABV） presents genetic diversity and has a significantly wide host range in China. Instead of the dog-and wildlife-associated China ⅠI lineage in the past decades, the China Ⅰ lineage has become the main epidemic group hosted and transmitted by dogs. In this study, four new lineages, including 43 RABVs from FBs, have been classified within the dog-dominated China Ⅰ lineage since 2014. FBRABVs have been previously categorized in the China Ⅱ lineage. Moreover, FB-hosted viruses seem to have become the main independent FB-associated clade in the phylogenetic tree. This claim suggests that the increasing genetic diversity of RABVs in FBs is a result of the selective pressure from coexisting dog rabies. FB transmission has become complicated and serious with the coexistence of dog rabies. Therefore, apart from targeting FB rabies, priority should be provided by the appropriate state agencies to perform mass immunization of dog against rabies.展开更多
