1·Thus, it is significant to synthesize the organic-inorganic hybrid silver (copper) iodide polymer and investigate the rule of assemble, structure and the relation between structures and properties.

因此，合成一些新型的含银(铜)-碘的有机无机杂化聚合物，研究其反应组装规律、结构规律、性能和构效关系具有十分重要的意义。

2·Conceal disturbing elements like iron, copper, lead with hydrogen fluoride amine-EDTA, add the potassium iodide to separate iodine, and take starch as indicator, titrate with sodium hyposulfite.

试样以王水分解、泡塑富集分离金，硫脲解脱，以硝酸-硫酸破坏硫脲，用氟化氢胺- EDTA掩蔽铁、铜、铅等干扰元素，加碘化钾使之析出碘，以淀粉为指示剂，用硫代硫酸钠进行滴定。
