运用模拟污染物的同位素示踪技术探索了稳定同位素载体对青菜吸收１４１Ｃｅ 的影响， 结果表明，青菜植株及其各部位中１４１Ｃｅ 浓度与载体引入量间均呈线性负相关；青菜各部位中１４１Ｃｅ 浓度的大小顺序是：根＞ 地上部， 而地上部的枯黄叶＞ 老叶＞ 嫩叶⒚ The effects of stable isotope vectors on 141Ce uptake by Chinese cabbage were explored by isotope tracing techniques using simulated contaminants. The results showed that there was a linear negative correlation between 141Ce concentration and the amount of carrier introduced in vegetables. The concentration of 141Ce The size of the order is: root> aboveground, while the ground above the yellow leaves> old leaves> young leaves ⒚
