PURPOSE:To accurately refine an extremely low-P Cr steel when a molten Cr steel is refined by adding ferrochrome contg. P as an impurity to a molten steel under dephosphorization, by well dephosphorizing the molten steel until the Cr content reaches <10%. CONSTITUTION:Ferrochrome contg. P ...
containing sulfide iron nodules and gangue. The coal seam is mainly composed of bright coal with a strip like structure, belonging to high volatile matter, extra-low phosphorus, high sulfur, medium to strong cementation, low to medium ash coals, containing SiO2, Al2O3, Fe2S3,...

Taken together, our results indicate that OsPHT1;3 acts as a crucial factor for Pi acquisition, root-to-shoot Pi translocation, and redistribution of phosphorus in plants growing in environments with extremely low Pi levels. 展开 DOI: 10.1104/pp.18.01097 年份: 2018 ...

On the other hand, in applications in which high levels of ionizing radiation and high optical power levels are experienced it may be beneficial to have high phosphorus levels, and a phosphorus rich composition may be desirable. The ... DJ Digiovanni 被引量: 0发表: 1999年 [OSA Integrated Ph...
the Ems-Dollard estuary, and near Norderney and Büsum, Germany (Tillmann et al.2000; Colijn and Cadée2003). Only at the end of the spring bloom, in June, a few hours per day nutrients (silicon, phosphorus and in some cases nitrogen) were found to be limiting (Tillmann et al.2000)...
of rather recently arriving species. On the contrary, surrounding phosphorus-poorer grasslands still contain the ancient species pool whose extraordinary size determines the exceptional species richness of grasslands in the study region. Its maintenance or restoration demands a persistent phosphorus deficiency...
the membrane associated carbon-phosphorus lyase complex PhnG-M that participates in the degradation of phosphonates and a phosphate/phosphonate transporter of the major facilitator superfamily, the phosphorus regulon regulator PhoB and surface layer proteins of unknown function. These genes are associated ...
Further, after pouring the extremely low phosphorus high nickel-containing molten iron into a decarburizing furnace 2, the metallic nickel is charged and the decarburized blowing is started and the nickel oxide is charged at the end stage of blowing.;COPYRIGHT: (C)1996,JPO...
