利用化学预处理与气相色谱—同位素质谱相结合的分析手段，在国内首次完成了原油中甾花生物标志化合物的联同位素鉴定。选择我国济阳拗陷八面河油田典型低成熟油作为样品，对其昌萜生物标志化合物的碳同位素的特征进行了初步探讨。
The combination of chemical pretreatment and gas chromatography-mass spectrometry (GC-MS) was used to identify the isotopes of the biomarkers in China. The typical low mature oil from Bamianhe Oilfield in Jiyang Depression of China was selected as a sample to investigate the carbon isotope characteristics of the biomarkers of the terpenoids.
