摘　　要：报道了连续氢化物发生-电加热石英管-原子吸收光谱法实验系统.并以铅烷(PbH_4)发生为代表对氢化物发生器构型、残留液体积、原子化温度、石英管电加热区域长度、载气流速、测量波长选择、泵速、进样管长度等诸多影响因素作了试验.An experimental system of continuous hydride generation-quartz tube atomization-atomic ab-sorption spectrometry is reported. A test for the practice of the system is made taking the generation of PbH, as an example. The influence of the structure of hydride generator, heating length of the quartz tube, atomization tem-perature, flow rate of carrier gas, analytical line selection, flow rate of the reactants are discussed.
