碳同位素分馏 meaning in English
carbonisotope fractionation
Examples
- Carbon isotope discrimination and water use efficiency in different soybean and wheat genotypes
大豆和小麦不同基因型的碳同位素分馏作用及水分利用效率 - The comparison of stomatal parameters in leaf cuticles between two fossil angiosperms from the pliocene in west yunnan and their nearest living equivalent species indicates a little higher atmospheric co2 level at that time than the present , while carbon isotopic composition of fossil cuticles demonstrates much higher carbon isotopic discrimination and slight lower water use efficiency , showing a warmer and wetter climate than today
摘要对滇西腾冲新近纪两种被子植物叶片及其现存对应种的气孔参数和碳同位素组成的综合分析表明：当时的大气co2浓度略高于现在水平；化石种的碳同位素分馏值高于现存对应种，但水分利用效率低于现存对应种；这证明当时的气候条件比当前更为温暖湿润。
