摘　　要：W元素的添加可以改善电触头材料的抗熔焊性。为准确测定合金触头中的W含量,本文提出了富氧空气-乙炔火焰原子吸收光谱法,并研究了仪器工作条件,优化了实验步骤。该方法操作简便,实用性强。The addition of tungsten could improve the welding resistance of cotact materials. To measure the content of tungsten in silver alloy contacts, this paper points out a new method, which is named oxygen enriched air-acetylene flame atomic absorption spectrometry. The work condition of instrument is also studied, and the test process is optimized. Results show that the new method with high practicability is easier to operate.
