Abstract : the formation of traditional v extraction from coal stone isreviewed in hunan province . the paper described several currently applied new processes for v extraction from coal stone . suggestions are put forward for further development of v extraction from the coal stone 文摘:回顾了湖南石煤提钒传统工艺的形成过程，介绍了目前已在生产上应用的几种石煤提钒新工艺，对促进石煤提钒的进一步发展提出了建议。
It is used to distinguish reaction process of converter vanadium because presently , a mature and dependable mathematic model is still not in existence , which can control and guild converter vanadium process how to operate . according to test data from laboratory before distilling vanadium , the model in practice is used to predict how to control operation for ensuring effect of distilling vanadium and quality of middle - stage - steeling . after adopting the model , the goal of " distilling vanadium and simultaneously reserve carbon " is realized successfully 针对目前国内外还没有一种成熟可靠的数学模型来对转炉提钒过程如何操作进行控制和指导，用该算法辨识转炉提钒的反应过程；并且在实际生产运行中，根据提钒前的检验数据来预测提钒时应该怎样进行操作才能保证良好的提钒效果和半钢质量，从而达到工艺生产目标的实现。
Lithium vanadium oxides display high capacity and low price as cathode materials for lithium ion batteries . lithium vanadium oxides , however , are hard to be synthesized because of the various valences of vanadium . if the factors of price and comprehensive electrochemical properties a re considered , the cathode materials of ( lithium ) vanadium oxides should be recognized as the most potential cathode materials for lithium ion batteries (锂)钒氧化物类正极材料容量大、价格低，但由于钒的多价态导致(锂)钒氧化物类正极材料制备困难，如果考虑价格和综合电性能等因素， (锂)钒氧化物类正极材料更具有实际使用价值，所以(锂)钒氧化物类正极材料被越来越多的研究者认同为是新一代最具发展潜力的锂离子电池正极材料。
In this paper , high concentration vanadium electrolyte has been prepared by electrolysis , graphite and graphite felt electrode also have been made , moreover , the electeodes have been activated , and based it , a lab - level vanadium battery has been manufactured . cyclic voltammetry , current step and invariable current charge / discharge method have been used to study the reactive mechanism of electrolysis , of vanadium electrode reaction and of electrode activation , also to investigate maiden charge process and electricity performance of vanadium battery . the influence of electrode activation and trace stibium ion , indium ion added into vanadium electrolyte has been discussed 利用循环伏安法、恒电流阶跃法、恒电流充放电循环等电化学方法，探讨了电解法制备钒液流电解质的反应机理，考察了钒的电极反应、电极表面活化处理对钒的电极反应的影响，结合电极反应分析了活化的机理；还考察了钒电池初次充电活化过程及恒流充/放电循环的电性能；并且考察了添加锑离子、铟离子对钒电池电性能特别是析氢行为的影响。
This paper introduced the improves of roasting - sodium processing and such pollution - free processing as acid leaching - extration , roasting in air - acid leaching - extration , liming roasting - alkali leaching on extraction of v2o5 from stone coal , the total recovery rate obtains enhances , the industrial application prospect is good 摘要介绍了石煤提钒传统工艺的改进以及酸法萃取、无盐焙烧酸浸萃取、氧化焙烧碱浸等几种从石煤无污染提取五氧化二钒的工艺流程，上述工艺不但生产过程无环境污染，钒的回收率还大有提高，是很有前途的清洁生产工艺。
