technically, it is not ordinary diesel,either: in chemist-speak, it is an isoprenoid rather than a mixture of alkanesand aromatics.
从技术上讲,它并不是普通的柴油,从化学家的角度来讲,它是一种类异戊二烯而不是烷烃和芳香烃的混合物。
aryl isoprenoid compounds in the aromatic fraction of sedimentary organic matter have been regarded as a biomarker that indicates a saline and strongly reducing sedimentary environment.
芳基类异戊二烯化合物被认为是高盐和强还原沉积环境中沉积有机质芳烃馏分中的特征性生物标志物。
the results show that there are n-alkanes, isoprenoid alkenes, terpenes and stericles in the organics.
