It is suggestedthat the α--C_(7) Sterane ββ/ (αα+ββ) and α-C_(9) Sterane 0S/ (0R+0S)are the main indices of crude oil maturity, while the relative abundance ofrearranged Sterane, -methylsterane and Tm/Ts are of secondary importance.

α-C_(7)甾烷的ββ/(αα+ββ)和α-C_(9)甾烷的0S/(0R+0S)是反映原油成熟度的主要指标,重排甾烷相对丰度、-甲基甾烷相对丰度和Tm/Ts是原油成熟度的辅助指标。
