This report based on the results of investigations conducted in June 2007 and July 2008, respectively, on the benthic community structure and characteristic diversity of the Huanghai Sea （Yellow Sea） Cold Water Mass, as well as that in July 1959 during the national oceanic survey. The Naticidae specimens collected from Cold Water Mass in middle and northern Huanghai Sea were studied through morphological classification and the internal anatomy on radula. Three new species of Naticidae, i.e., Cryptonatica purpurfunda sp. nov., Cryptonatica sphaera sp. nov., and Cryptonatica striatica sp. nov. were identified. The morphological characteristics of the new species are described, and the similarties and differences between the new species and similar species are compared and discussed.

The West Mine of the Bayan Obo deposit, located in the northern-central part of Inner Mongolia, China, is enriched in Nb, rare earth elements and iron （Nb-REE-Fe） mineral resources. This paper presents a combined method to explore metallogenic correlation of the Nb-REE-Fe mineralization at the Bayan Obo West Mine. The method integrates factor analysis and Back Propagation （BP） neural network technology into processing and modeling of geological data. In this study, the Nb and REE contents of samples were transformed into discrete values to analyze the correlations among the metallogenic elements. The results show weak mineralization correlations between Nb and REEs. Nb and U are closely related in the geochemical patterns, while Fe is closely related to both Th and Mn. LREEs are an important factor for the mineralization of the Bayan Obo deposit, while Fe and Nb can be considered as the results of passive mineralization. On the basis of a metallogenic correlation analysis, the factors affecting the Fe-REE-Nb mineralization were extracted, and the Nb mineralization model was established by the BP neural network. Based on the BP neural network data computing, the variability of the Nb concentration displays a coupled multi-factor nonlinear relationship, which can be used to reveal the inherent metallogenic elemental regularities and predict the degree of element mineralization enrichment in the mining area.

Yttria stabilized zirconia (YSZ) has widely been used as electrolyte in solid oxide fuel cell (SOFC). The microstructure of YSZ related to the fabrication process was discussed in the paper. With YSZ nano-powders about 40-100 nm as raw material, the YSZ adobe was manufactured by tape calendering process. The named three-step sintering process was performed at 1000 ℃ for 2 h, then raised the temperature with normal rate and as soon as up to 1400 ℃, the furnace was controlled at 1250-1300 ℃ for 10-20 h. The high dense YSZs with the relative density of 96%-99% were obtained; the grain size of YSZ could be reduced to 0.5-3 μm. The above result is benefited to co-fired in the electrode-supported SOFCs.

Based on the AVO theoretical modeling of the coalbed, this paper analyzes the AVO characteristics and influencing factors of the coalbed P-P reflection wave. On the top interface of the coalbed, the P-P reflection wave absolute value of reflective coefficient decreases when the incidence angle increases between 0 and 60 degrees, and then increases gradually. On the bottom interface of the coalbed, the total reflection occurs rather strikingly because the incident wave propagates from low impendence media to high one. And for the soft and fractured coal in particular, such a phenomenon takes place even at an incidence angle less than 15 degrees. So the reflection characteristics of the coalbed bottom interface are not conducive to AVO analysis. AVO response is closely relative to the coal structure, and AVO intercept and gradient of top interface of the coalbed reflection wave increases when the coal structure is destroyed severely. For coalbeds of the same coal structure, AVO intercept and gradient of the coalbed top interface with the sandstone roof is greater than that with the mudstone one. The tuning of coal-bed thickness has adverse influence on coalbed AVO attributes analysis obviously. Those AVO characteristics of coalbed are shown further by modeling from Well 9-10-15 and Well 10-E-3 in Huainan coalfield, China.

Urbanization is an inevitable trend in the modernization of human society. The Chinese government has put forward a goal for urbanization in China in 2014, which focuses on the three tasks, each containing 100 million people. In the next lOyears, China＇s urbanization process will occur at the fastest rate in her his-tory. Earth＇s near surface, which extends from the ground surface to a depth of nearly 100 m, is the most complex, sensitive, and fragile part of the planet. The near surface provides the vast majority of nec-essary materials, along with substantial space for human living. Therefore, China＇s urbanization relies on a ＂healthy＂ and sustainable near surface.
