It is characterized by two centroprezygapophyseal lamina fossae; large, square-shaped concavity formed by centroprezygapophyseal lamina and dorsal margin of the centrum; large infraparapophyseal fossa; three openings present within the large lateral concavity, which occupy 65% length of the centrum; the posterior centroparapophyseal lamina （PCPL） and the anterior centroparapophyseal lamina （ACPL） weakly developed; the posterior centrodiapophyseal lamina （PCDL） separated by an infradiapophyseal fossa into two branches dorsally; parapophyseal and diapophyseal laminae cross to form ＂K＂ configuration. It shares some characters with the Early Cretaceous form-Euhelopus, indicating that it is more closely related to Euhelopus rather than to other titanosauriform sauropods. This means Gannansaurus may have a close phylogenetic relationship with Euhelopus.展开更多

Based on multi-temporal TM and ETM satellite remote sensing data in 1985, 1996, 2000, and 2012, and by using corrected figures of land use status over the same periods, the spatial area of Ganzhou District since 1985 was extracted with statistical methods, and urban spatial expansion was measured by quantitative research methods. The characteristics of spatial expansion of Ganzhou District were analyzed by urban expansion rate, expansion intensity index, compactness, fractal dimension, and the city center shift method. The results showed that the built-up area of Ganzhou District increased by 3.46 times during 1985-2012. The expansion in 1985 1996 was slow, during 1996 2000 it was rapid, and during 2000-2012 it was at a high speed. This city mainly expanded to the northeast and northwest. Government decision making had a decisive influence on urban expansion. Initially the expansion was uniform, but later the local tfansportation, economy, resources, population, and national policies factors had an obvious influence on urban expansion.展开更多

The project is located in Xunwu Industrial Park and it is a new project. Products of the project includes didymium alloy, GdFe alloy, DyFe alloy and HoFe alloy produced by the purchased didymium oxide, gadolinium oxide, dysprosium oxide and holmium oxide or didymium fluoride, gadolinium fluoride, dysprosium fluoride and holmium fluoride through mixing, electrolytic furnace pretreatment, molten salt electrolysis, casting and other processes. The alkaline neutralization precipitated slag and water spray precipitated slag produced in the production process will be dried by electric furnace and crushed by ramon mill for comprehensive reutilization. After the completion of the project, the annual output of rare earth alloys will be 3,000 tons.展开更多

The new taxon differs from other oviraptorids in the weakly downturned rostrum of the lower jaw, much-elongated mandible with a height-to-length ratio being about 20% and the length ratio of radius to humerus of about 0.70. This species not only adds a new member to oviraptorid dinosaurs, but also provides more information about oviraptorid paleogeographical distribution in southern China.展开更多

Rare earth market kept rebounding from Jan. to May. The third round of national stockpiling ended on May 27. Total bidding amount reached over 3,000 tons. China Minmetals, Baogang Group, Chalco, Ganzhou Rare Earths, Rising Nonferrous Metals, Xiamen Tungsten and CNMC participated in the bidding. Prices of mainstream products were higher than the previous round. For instance, bidding price of europium oxide increased from the previous 500,000 yuan/ton to 570,000 yuan/ton this time, up 14%.展开更多
