The behavior of the rare-earth dissolved in steel, of the iron-cerium intermetallic compounds and of the rare-earth inclusions in electrolytic separation process was studied by means of radiolabelling method, electron probe and X-ray analysis. 用放射性同位素示踪法、电子探针和X射线分析研究了溶解在钢中的稀土、铈-铁金属间化合物和稀土夹杂物在电解分离过程中的行为。
The Distribution of oxide and oxysulfide inclusions of rare-earth metals in steel melts has been studied by means of radiolabelling method. 用放射性同位素示踪法研究了钢中稀土氧化物和稀土硫氧化物夹杂的分布。
In practice, the complicated procedure with radiolabelling and chromatographic separation of 3_phosphoglycerate and 2_phosphoglycolate was substituted by one_step procedure without radiolabelling and chromatographic separation to decrease the random error. 操作上避免了使用放射性同位素标记以及层析分离3磷酸甘油酸和2磷酸乙醇酸的复杂程序,使测定过程一步完成,极大地减少了随机误差。
