中文摘要：

采用扫描电镜（ SEM）和能谱（ EDS）联用分析技术，研究了铀在植物—微生物共生体系满江红中的分布，结果发现，铀在蕨类植物满江红和微生物满江红鱼腥藻中均有分布，满江红鱼腥藻中铀含量略高于蕨类植物满江红，表明了蕨类植物满江红和微生物满江红鱼腥藻都参与了去除水体中铀的过程。

英文摘要：

The distribution of uranium in the plant_microbe symbiotic system_Azolla imbir_cata was analyzed by scanning electron microscope（ SEM） and energy dispersive spectrom_eter（ EDS ） hyphenated technique. The results showed that uranium distributed in both fern_Azolla imbricata and microbe_Anabena azollae. The content of uranium in Anabena azollae was slightly higher than that in Azolla imbricata. The fern_Azolla imbricata and mi_crobe_Anabena azollae had a synergistic effect on the process of removing uranium from the water.
