Statistical study of analyses of water from 43 samples from geothermal wells, three groundwater wells, and one sample of local rainwater along with rainwater data from the Global Net- work of Isotopes in Precipitation has been used to identify the origin and evolution of geothermal water in the Niutuozhen （~f=~jg） geothermal field and estimate the renewability rate of its geothermal re- source. The results show that the geothermal waters of the Jixianian Wumishanian dolomite reservoir and the Ordovician limestone reservoir are of CI-Na type, the geothermal water of the Pliocene Minghuazben （H~/~） Formation sandstone reservoir are CI-Na type and HCO3-Na type and the groundwater of the Quaternary aquifer is HCO3-Na and *** type. A linear relationship between silica concentration and temperature indicates that higher temperature probably enhances concentration of silica in Jixianian geothermal water. 81SO shift in Wumishanian geothermal water av- eraged 1.57%o, and was less than 1%o in the other geothermal waters. The minimum and maxi-mum 14C ages of Wumishanian geothermal wa- ter are 17 000 and 33 000 years from north to the south of the Niutuozhen geothermal field. Geo- thermal water and Quaternary groundwater belong to different groundwater systems with no hydraulic connections. Although the geothermal field receives some recharge from the Yanshan and Taihang mountains outside the northern and western boundaries of the geothermal field re- spectively, the renewability rate of geothermal water is on the scale of 10 000 years.

The phylogenetic status of typical Chinese native pigs: analyzed by Asian and European pig mitochondrial genome sequences

引用

Journal of Animal Science and Biotechnology 2013年第2期2013卷 145-151页

作者： Guanghui Yu Hai Xiang Jikun Wang Xingbo Zhao National Engineering Laboratory for Animal Breeding Ministry of Agricultural Key Laboratory of Animal Genetics Breeding and Reproduction State Key Laboratory for Agribiotechnology College of Animal Science and Technology China Agricultural University

China is one of the most diverse countries, which have developed 88 indigenous pig breeds. Several studies showed that pigs were independently domesticated in multiple regions of the world. The purpose of this study was to investigate the origin and evolution of Chinese pigs using complete mitochondrial genomic sequences (mtDNA) from Asian and European domestic pigs and wild boars. Thirty primer pairs were designed to determine the mtDNA sequences of Xiang pig, Large White, Lantang, Jinhua and Pietrain. The phylogenetic status of Chinese native pigs was investigated by comparing the mtDNA sequences of complete coding regions and D-loop regions respectively amongst Asian breeds, European breeds and wild boars. The analyzed results by two cluster methods contributed to the same conclusion that all pigs were classified into two major groups, European clade and Asian clade. It revealed that Chinese pigs were only recently diverged from each other and distinctly different from European pigs. Berkshire was clustered with Asian pigs and Chinese pigs were involved in the development of Berkshire breeding. The Malaysian wild boar had distant genetic relationship with European and Asian pigs. Jinhua and Lanyu pigs had more nucleotide diversity with Chinese pigs although they all belonged to the Asian major clade. Chinese domestic pigs were clustered with wild boars in Yangtze River region and South China.

自公元前1044年始至1926年中国与朝鲜的诗歌交流持续约三千年，参与的诗人数千位，创作了数万首诗歌。中朝的诗歌交流无论从时间上的持续还是空间上的跨越，都是世界历史上绝无仅有的文化文学现象。从纵向来看，可以分为西周至东汉末、魏晋南北朝至宋末、元代至清末、光绪乙巳至民国十五年四大阶段，第一个阶段以咏史诗为主，第二阶段以追和诗为主，第三阶段以使行诗为主，第四个阶段为朝鲜遗民金泽荣在中国的交流诗。从横向来看，诗歌交流包含着十类文献：唱酬、献赠、追和、咏史、题咏、事迹、诗人、诗集、评价、制度背景。从国际上看，相较于东亚的日本、越南、琉球，朝鲜的诗歌交流具有独特的优势与特征。
