查询词典 uranium dioxide

In this paper, the progresses acquired in the studies of natural analogy are summarized, including a comparison of structural properties, radiation damage and chemical composition between uraninite and UO2, combination and paragenesis of alteration products of uraninite, chemical composition of uraninite and its secondary phases, mobility of analogy elements in the process of uraninite alteration. In addition, the problems in next studies are pointed out, e. g., characterization of micro-structure of secondary uranium minerals, high-resolution analyses of trance elements distributed in original and secondary uranium minerals using laser microprobe analyzer, composition of underground water, simulation experiments.
