Two polysiloxanes (SR2 and P67) and one polycarbosilane were chosen as preceramic polymers. TG-DTA-MS, FT-IR, XRD,〓Si MAS-NMR, SEM, TEM, SAD, HREM, chemical analysis and density measurement techniques were used to study the cross-linking and pyrolysis mechanisms of the preceramic polymers. The development of chemical composition and structure, density, phase composition and microstructure of the solid pyrolyzed products during pyrolysis process were systematically investigated. While pyrolysis temperature approached 1000℃, ceramization process of the preceramic polymers almost completed, and ceramic yield of the preceramic polymers hardly changed any more.

Produce the BF gas mud 100, OOOt every year. The raw mineral of puddling is the magnetite containing vanadium and titanium. The grade of iron is only 53%. The grade of sinter mineral is only 47-48%. So the percentage composition of iron is relatively low, only 29.70%. The grade of zinc is relatively high, reach 9.92%. And the percentage composition of carbon is relatively high, reach 16. 80%. In the next place, the BF gas mud is the production through sinter in high temperature.

攀钢炼铁的原矿物为钒钛磁铁矿，铁品位仅为53％，烧结矿品位为47％～48％，所以攀钢高炉瓦斯泥的铁品位也相对较低，仅为29.70％，并且含锌量高，达到了9.92％，含碳则高达16.80％；其次高炉瓦斯泥是高炉冶炼过程中的产物，SiO_2、Al_2O_3和铁部分熔融在一起，选矿难度增加。

Based on a quantitative analysis of radiolarian in 80 surface-sediment samples from the northern area of Okinawa Trough, this paper reported the species composition and faunal assemblages characteristic of radiolarian, expounded the distribution pattern of radiolarian abundance and diversity in surface sediments from this area. In this paper, a preliminary study on the relation of the distribution and abundance of radiolarian to environmental factors, such as chemical and physical properties of the overlying masses (sea-surface temperature, salinity, nutrients and primary productivity) and the type and composition of sea-bed sediments was made. The radiolarian data was evaluated using a Q-mode factor analysis to identify different faunal assemblages and their geographic distributions, then the relationship between radiolarian assemblages and distribution of water masses, hydrographic boundaries such as frontal systems was analyzed. A new radiolarian-based transfer function to estimate mean-annual sea surface temperature and seasonal range were examined to test its success in the study area.
