This paper introduces a new method which can obtain the extinction value linear to the concentration for the atomic absorption spectrometry (AAS) and atomic resonant fluorescent spectrometry (ARFS).

提出一种使原子吸收与原子共振荧光光谱分析均能得到与被测元素浓度成线性关系的消光值的方法。

The calculation result shows that the maximum of the extinction spectrum depends on the refractive index in a linear way.

结果表明，银纳米粒子的最大消光位置随所处介电环境折射率的增加呈现明显的红移现象，两者之间的关系大体呈线性。
