摘要
通过实验证明了难电离元素Sb(E_i=8.64eV)对交流电弧等离子体中痕量元素的光谱线强度有增强效应,并对增强效应的机理进行了研究。
The enhancement effect of non- easily ionized element Sb, whose ionization potential is 8. 64 eV,on the spectral line intensity of trace elements in an a. c. arc plasma was proved by expariments. The mechanism of this enhancement effect was also investigated.
