图1 GDGTs结构（据参考文献［13］修改） （a）类异戊二烯GDGTs结构和（b）支链GDGTs结构；由于甲基位的异构，支链GDGTs具有5-和6-甲基支链GDGTs异构体

Fig.1 Molecular structures of GDGTs（modified after reference［13］） Molecular structures of iGDGTs（a）and bGDGTs(b); Due to the heterogeneity of the methyl positions，branched GDGTs have 5- and 6-methyl branched GDGTs isomer
