free carbon

The studies of n-alkanes and compound-specific carbon isotopic compositions not only can help us reconstruct the paleo-vegetation and paleo-climatic changes, but also are involved in one of the most spectacular and interesting environment scientific questions in recent years.

与古植被、古气候变化密切相关的正构烷烃分子化石及其单体碳同位素的研究是近年来最为引人注目和关切的环境科学问题之一,这一研究在国际上已取得了一定的成果。
