【摘要】 用国产铅合金标准样品在光源的激发下建立各元素的工作曲线,将待测样品经过车床车制后,用建立的工作曲线测定其合金中的主要元素 Sb、Sn 及杂质元素 Cu、Zn、Fe、As、Bi 等的含量,与精确化学分析法得出的分析结果进行对比,结果令人满意。更多还原

【Abstract】 The working curve of every element in the standard samples of thehomemade lead alloy was set up under the excitation of source. After lathing samples, the main elements, Sb and Sn, and impurities, Cu, Zn, Fe, As, Bi etc., were determined by the built working curves. The result which was compared with the analytic results obtained from the method of accurate chemical analysis was satisfying.更多还原
