摘　　要：以往认为完整的碳同位素值正序排列是天然气有机成因的特征,完整的反序排列是天然气无机成因的特征。而费-托合成实验的结果中,两种碳同位素值排列都有存在。通过费-托实验基本条件分析与产物同位素特征分析,论证了天然气甲烷同系物碳同位素值正序或反序排列特征是无机合成的必然结果。Much interest is focused on carbon isotope value sequence of methane and its homologue in products of Fischer-Tropsch synthesis experiment. In the past it is considered that complete positive sequence of carbon isotope is characteristic of organic genesis of natural gas, while complete inverted sequence is inorganic genesis. However, both sequences exist in Fischer-Tropsch synthesis experiment result. Analysis on basic conditions and products isotope of Fischer-Tropsch experiment proves that positive or inverted sequence of carbon isotope of methane and its homologue of natural gas is the consequent of inorganic synthesis.
