采用果酒工艺制备紫甘薯酒，用还原能力、清除DPPH自由基能力、抑制脂质过氧化能力、金属螯合能力，研究了紫甘薯酒的抗氧化活性。

The efficiency of re-extraction using reused EDTA reached the original level of chelating extraction only for sludge B.

Fe置换螯合铜后之DTPA悬浮液可再利用於萃取A、B或C污泥中之重金属，而Fe置换螯合铜后之EDTA悬浮液则仅可再利用於萃取B污泥中之重金属，这是B污泥中重金属结合型态多为易萃出之可交换态与碳酸盐态所致。

The central 5, 5'-disubstituted bipyridine units of each ligand coordinate theNi or Fe ion, while all the terminal 6-monosubstituted bipyridine units of the ligands keep free of coordination, as the result trinuclear triple-stranded helicate 〓 can not form. This is considered to be caused by the steric hindrance of the methylene substituents α to the chelating nitrogens of the terminal bipyridine units and the strain caused by linkage mode.

配体L〓与Ag作用得到〓，两个配体链相互缠绕着两个Ag离子周围形成双股螺旋结构并以头尾式排列(见图3)，由于配体中位于配位N原子α或β位的末端甲基或次甲基取代基的空间位阻阻碍了头对头式异构体的形成，也正是由于配体头尾式排列而使Ag双股螺旋得以形成，这一结果表明该螺旋体的组装过程中自发地采取了空间阻碍尽可能小的那个构型。
