The results show that photocatalyst TiO2 improves the removal rate of toluene in not only the nitrogen plasma field (NTP-P-O2/N2) eradiating ultraviolet light but also the argon plasma field eradiating visible light. This supports the idea that both the UV light and the high-energy electron in the plasma field can activate TiO2. Furthermore, the toluene removal rate in NTP-P-Ar system is 5% higher than that in NTP-P-O2/N2 system, confirming that high-energy electron has greater effect on the degradation performance of toluene, as compared with UV light.

结果表明：在发射紫外光的氮等离子体场(NTP-P-O2/N2)中和发射可见光的氩等离子体场中，TiO2：均能提高体系的甲苯去除率，说明等离子体场中产生的紫外光和高能电子均能激活光催化剂TiO2；NTP-P-Ar体系中的甲苯去除率较NTP-P-O2/N2：体系中的约提高5%，说明等离子体场中高能粒子对甲苯降解性能的影响要强于紫外光的影响。

By injecting commercially pure argon to make pressure in furnace up to 66.66 kPa and controlling refining temperature between 1 450 ℃ to 1 500 ℃, adding Mg-Ca alloy 50 kg/t and fluxed additions CaF\-2 11 kg/t, after refining the phosphorus content in steel 00Cr18Ni10 further decreased to (50～60)×10 -6, and oxygen and sulphur content in steel decreased to (4～6)×10 -6 and 15×10 -6 respectively.

采用CaC2 CaF2 法脱磷容易增碳，使后期冶炼工艺复杂，因此最好在吹氧前使用；CaC2 CaF2 也可用作喷吹SiCa粉脱磷时的覆盖渣，可起到保持还原气氛的作用。SiCa CaF2 法是唯一在工业规模上有少量应用的还原脱磷法，而且氧化脱除增加的硅比较容易。
