So high-sensitivity detection method becomes greatly important to the pesticide residua and their metabolites .

因此，对农药残留物及其有害代谢物的高灵敏度检测就变得异常重要。

In this paper the technology of fluorescence spectroscopy is applied to theoretical and experimental study of pesticide residua detection .

本文利用荧光光谱法对化学农药残留物检测方法进行了理论与实验研究。
