1980年11月,日本外宾新日铁公司基础研究所分析研究中心田口勇先生来我国访问,先后在北京和上海作了他所研究的非水溶剂选择性恒电位电解浸蚀法(SPEED)的报告。这是一种钢铁中的相分析快速法新技术。按国内常规,用水溶液电解液恒电流电解法作一次相分析,电解时间约需2小时,从溶解、萃取、分离到鉴定约需要十天的时间,而用SPEED法,电解时间只需十秒钟,即使加上其他辅助工作时间,工效也可提高数百倍。但是一年多来,SPEED法在国内尚末充分开展,这与对这种方法不够熟悉有关。现安排整理成文,希望这一方法有助于加快相分析的速度,为祖国的四化建设作出贡献。
In November 1980, Mr. Taguchi Yong, Director of the Analytical and Research Center of the Nippon Steel Corporation’s Nippon Steel Research Institute, visited our country and made his SPEEP report in Beijing and Shanghai successively. . This is a rapid phase analysis of steel in the new technology. Accordance with the domestic routine, the use of aqueous solution of constant current electrolysis electrolysis for a phase analysis, electrolysis time of about 2 hours, from dissolution, extraction, identification of the separation takes about ten days time, and SPEED method, electrolysis time only 10 seconds Bell, even with other auxiliary working hours, ergonomics can be increased hundreds of times. However, for more than a year, the SPEED method has not been fully implemented domestically, which is not so familiar with this method. Arrangements are now arranged and written, I hope this method will help speed up the phase analysis, to contribute to the motherland’s four modernizations.
