引言分子荧光是非地震找油的重要指标之一。通常采用固定波长法测土壤中的发荧光物质，此方法对发荧光物质的定性、定量分析比较困难，而且谱峰重叠严重，难以分辨，采用同步扫描技术可以使光谱简化，谱带变窄，在同时测定多种芳烃时，大大提高了分辨率。由于多环芳烃的斯多克 Introduction Molecular fluorescence is one of the important indicators for non-seismic oil search. Usually the fixed wavelength method is used to measure the fluorescent substances in the soil. This method is difficult to quantify and quantify fluorescent substances, and the spectral peaks overlap very hardly and are difficult to distinguish. Using synchronous scanning technology can simplify the spectrum and narrow the spectrum. In the simultaneous determination of a variety of aromatics, the resolution has been greatly improved. Due to polycyclic aromatic hydrocarbons
