| 摘 要： | 本文提出一种新的思想:不用分光器件的原子吸收测定。其方法是必须对直流供电的光源所发射的光谱线进行共振吸收调制,而光电检测器只测量被调制过的光谱信号。光强差理论分析表明,这样不但可省去分光镜,而且由于同时测定多条谱线,测定灵敏度和准确度也显著地提高。

| Abstract: | A new idea:The determination of atom absorption but not apply the spectroscope.The method is that must make resonance absorption modulation of spectrum lineemited by the light source in direct current,and the photoelectrometer determine only the spectral signal was modulated.The intensity difference theory analysis show that not only can omit the spectroscope,and also the sensitivity and accuracy of determine is being raised strikingly becasue of the multi-spectrum line was determined simultaneously. |
