摘　　要：研究了单火花光谱在不同采样时间段分析灵敏度与窗口的关系，P、S、Al、Ni、Ti、B、Mg、Sb、Pb、As、Bi、Ta、Sn用TRS技术检出限明显降低，而C,Si、Mn、Cr、Mo、V、W、Co、Nb则不显著；合适的采样窗口能提高Sb的分析准确度，Mg则可减少背景波动带来的影响，Cu可扩大分析线性范围；采用TRS技术在诸有效元素中分析灵敏度可提高1．36—5．00倍，能更好地满足品种钢的研究开发与生产检验的需求。It researches the relations between sensitivity and window under the different sampling stages by means of single spark spectrum.For P,S,Ni,Ti,B,Mg,Sb,Pb,As,Bi,Ta, Sn,the test results decrease apparently, but C,Si,Mn, Cr, Mo,V,W, Co,Nb,not so obviously.Suitable sampling window could increase the analyzing accuracy of Sb,Mg could decrease the influence from background fluctuation, Cu could enlarge the analyzing linear scope. TRS technology also could increase the analyzing sensitivity 1.36 - 5.00 times which meets the requirement of steel grades research and production inspection.
