在烃类天然气中,由于稀有气体的含量很微,所以其同位素组成的检测相对较困难。
The measurement of the noble gas isotopes in hydrocarbon natural gases is relatively difficult because their content is very low.
即不同金管之间气态烃的相对含量和碳同位素组成差异很小。
The proportional and carbon isotopic compositions of hydrocarbon and non-hydrocarbon gases are almost identical among these gold capsules.
