前言 在过去,有几个研究者已经应用了不同的方法阐明了从格林河油页岩内分离出的干酪根结构。这些方法的基本途径常常是把干酪根基质降解成能够使用常规的实验室仪器分析的比较小的结构成分。干酪根结构的复杂性使得要选择适当的研究干酪根的方法遇到了困难。关于干酪根结构的研究,曾经有人报导了明显不一致的结果,这主要是由于干酪根降解的程度和所利用的分析技术不同 Preface In the past, several researchers have applied different methods to elucidate the kerogen structure isolated from the Green River oil shale. The basic approach to these methods is often to degrade the kerogen matrix into relatively small structural components that can be analyzed using conventional laboratory instruments. The complexity of the kerogen structure has made it difficult to choose the proper method of studying kerogen. There have been reports of noticeable inconsistencies in the study of kerogen structure, mainly due to the different degree of kerogen degradation and the analytical techniques used
