摘　　要：本文从效率示踪源淬灭水平,化学、颜色猝灭成分以及增益选择等方面对效率示踪法作了改进的探讨,适当猝灭且有较高增益会给出更小的校正误差,谱形校正是改进效率示踪法的一个根本途径。The effect of different factors,which are quenching level of efficiency tracing source, chemical and colour quenching content and gain selection, on corrected errors by Efficiency Tracing Technique were studied. Appropriate quenching with higher gain can give lower corrected error. The correction of spectrum shape will be a essential way for overcoming dpm deviation of colour and chemical quenching.
