terpane的音标

The biomarkers of the oil are characterized by the followings: the content of pentacyclic terpane is larger than that of tricyclic terpane, with C_ ( 30) hopane and C_ ( 29) norhopane as the dominant components, and gammacerane as the minor component;

原油生物标志物特征是，五环萜烷含量高于三环萜烷，以C30-藿烷、C29-降藿烷为主，伽马蜡烷含量少；

Crude oil analyses, such as group compositions, carbon isotopes and gas chromatograms of saturated hydrocarbon, as well as characteristics of terpane, sterane and other biomarkers, indicate that crude oil in Yanchang-Yan'an Formations in Ansai-Fuxian area have similar geochemical behaviors and are of low-mature-mature oil.

原油族组成、碳同位素、饱和烃气相色谱及萜烷、甾烷等生物标志化合物特征分析显示，鄂尔多斯盆地安塞-富县地区延长组-延安组原油地球化学特征相近，为低成熟-成熟原油。

This paper uses technology of heavy hydrocarbon concentration of natural gas to detect biological markers of sterane and terpane, and defines gas-source of biodegradation gas with the aid of data of rare gas isotopes Basis is provided for Clarifying exploratory target.

本文利用天然气重烃富集技术，在天然气中检测出了甾萜生物标志物，并借助稀有气体同位素资料，确定了该类气体的气源，为明确勘探目标提供了依据。
