(Table 4) Pyrolyzate hydrocarbons for various temperature ranges at DSDP Leg ...

These values do not represent the true pyrolysis products, since olefins are not differentiated from napthenes by the mass spectrometer or the Robinson (1971) computer program....

本数据集给出的数值无法代表真实热解产物（pyrolysis products），原因在于质谱仪（mass spectrometer）与罗宾逊（1971）计算机程序均无法区分烯烃（olefins）与环烷烃（naphthenes）。
