For pre treatment of hot metal, both desulphurization and dephosphorization are improved with the increase of CaO in slag, but deteriorated with the increase of CaF 2 in slag. The average desulphurization and dephosphorization rate is 68 83 % and 78 46 %, respectively. For molten steel, the substitution of BaO for CaO in slag has minor effect on simultaneous desulphurization and dephosphorization. The desulphurization and dephosphorization rate is higher than 90 % and 50 % respectively with the lowest final sulfur and phosphorus mass percent being 0 001 2 % and 0 010 %, respectively. The overall effect of simultaneous desulphurization and dephosphorization of molten steel is better than that of hot metal.展开更多

As Karst pointed out, the information society is culturally and institutionally diverse. If in their transformation into social morphology information technology and capital may both end in socialism as well as capitalism, then what is the essential distinction between information capitalism and information socialism?展开更多

However, isolatedmedial rectus palsy due to a tiny infarction lesion was rarely seen.An 80-year-old man with a 10-year history of hypertension and diabetes, presented to the hospital for a sudden onset of diplopia. Neurological examination of cranial nerves revealed left medial rectus palsy when gazing to the right side （Figure 1A）. Other saccadic eye movements, the direct and indirect pupillary light reflex, eyelid activity were normal.展开更多
