伽莫夫,喬治1904 1968俄國裔的美國核物理學家,因在射線遺傳信息方面的研究和有關普及物理理論的書籍而聞名於世Vanadium is important and valuable in steel - making, electronic production and national defence industry etc. now, the operation pattern of refining vanadium in our nation is based on human experiences, and the automation degree is still at a low level. operation mode based on human experiences is one of the main reasons make the quality of semi - steel and vanadium product unstable. in developed contury such as russian, static model was used to control the process of vanadium refining
我國目前的轉爐提釩為人工操作模式,由操作人員根據經驗和感覺進行操作,自動化水平低,存在著釩渣質量和半鋼質量不穩定的問題;在國外,俄羅斯等一些國家已經在使用靜態模型對提釩過程進行控制,取得了較好的效果,但是這些模型大都是根據復雜的物理化學規律研製的機理模型,要求有非常穩定的生產流程和工藝條件,對于鐵水成分、生產設備等變化的適應性差,不但移植困難,而且模型價格異常昂貴。In the 1960s russian physicist victor veselago noted that in a material where both those quantities are negative, the refractive index will also be negative
